解决问题

前言

本篇文章是《一步一步学SpringBoot(二)》教学视频的简单课件,内容不是很详细,想了解全部内容,可以到上面的视频地址观看学习。

Spring Boot拦截器Interceptor

1)Spring boot拦截器默认

  • HandlerInterceptorAdapter
  • AbstractHandlerMapping
  • UserRoleAuthorizationInterceptor
  • LocaleChangeInterceptor
  • ThemeChangeInterceptor

preHandle****:**预处理回调方法,实现处理器的预处理(如登录检查),第三个参数为响应的处理器(如我们上一章的Controller实现);

返回值:true表示继续流程(如调用下一个拦截器或处理器);

​ false表示流程中断(如登录检查失败),不会继续调用其他的拦截器或处理器,此时我们需要通过response来产生响应;

postHandle****:**后处理回调方法,实现处理器的后处理(但在渲染视图之前),此时我们可以通过modelAndView(模型和视图对象)对模型数据进行处理或对视图进行处理,modelAndView也可能为null。

afterCompletion****: 整个请求处理完毕回调方法,即在视图渲染完毕时回调,如性能监控中我们可以在此记录结束时间并输出消耗时间,还可以进行一些资源清理,类似于try-catch-finally中的finally,但仅调用处理器执行链中preHandle返回true的拦截器的afterCompletion

2)配置spring mvc的拦截器WebMvcConfigurerAdapter

public class WebAppConfig extends WebMvcConfigurerAdapter  

具体类如下:

package com.example.interceptor.test;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

/**
 * Created by Ay on 2017/8/23.
 */
@Configuration
public class InterceptorConfig extends WebMvcConfigurerAdapter {


    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new UserSecurityInterceptor()).addPathPatterns("/springdata/*");
    }


}

3)实现添加拦截器方法

public void addInterceptors(InterceptorRegistry registry){  
}

registry.addInterceptor可以通过此方法添加拦截器, 可以是spring提供的或者自己添加的

具体类如下:

package com.example.interceptor.test;

import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Created by Ay on 2017/8/23.
 */
public class UserSecurityInterceptor implements HandlerInterceptor {

    @Override
    public boolean preHandle(HttpServletRequest request,HttpServletResponse response, Object handler) throws Exception {
        //业务处理
        System.out.println("preHandle");
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request,HttpServletResponse response, Object handler,
                           ModelAndView modelAndView) throws Exception {
        //业务处理
        System.out.println("postHandle");
    }

    @Override
    public void afterCompletion(HttpServletRequest request,HttpServletResponse response, Object handler, Exception ex)throws Exception {
        //业务处理
        System.out.println("afterCompletion");
    }

}

4)定义控制层进行测试

具体类如下:

package com.example.interceptor.test;

import io.swagger.annotations.ApiOperation;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author Ay
 * @date   2017/1/24.
 */
@RestController
@RequestMapping(value="/springdata")
@EnableAutoConfiguration
@EnableScheduling
public class AyInterceptorsTestController {

    @RequestMapping("/ay")
    @ApiOperation(value = "ay",httpMethod ="GET", response = String.class,notes = "index")
    public String index(){
        return "Hello Ay...";
    }

    @RequestMapping("/test")
    @ApiOperation(value = "test",httpMethod ="GET", response = String.class,notes = "index")
    public String test(){
        return "Hello Ay...";
    }
}

Spring Boot集成MongoDB

假如你已经安装好了mongoDB数据库,并新建了一个test数据库。那么开始吧

1)pom文件添加依赖

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

2)创建实体

package com.example.mongodb.test;

import org.springframework.data.mongodb.core.mapping.Document;
import javax.persistence.Id;

/**
 * 描述:
 * @author Ay
 * @date   2017/08/22
 */
@Document
public class AyTest {

    @Id
    private String id;
    private String name;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

3)服务层

package com.example.mongodb.test;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.stereotype.Component;
import java.util.List;

/**
 * Created by Ay on 2017/8/23.
 */
@Component
public class UserDaoImpl {

    @Autowired
    private MongoTemplate mongoTemplate;

    public void save(){
        AyTest ayTest = new AyTest();
        ayTest.setId("2");
        ayTest.setName("al");
        mongoTemplate.save(ayTest);
    }

}

4)application.properties添加配置

###mongodb
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=test

5)测试

package com.example.mongodb.test;
import com.example.intellij.test.AyTest;
import com.example.intellij.test.AyTestService;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by Ay on 2017/1/24.
 */
@RestController
@RequestMapping("/mongo")
public class MongoDBTestController {

    @Autowired
    private UserDaoImpl userDaoImpl;

    @RequestMapping("/al")
    public String index2(){
        userDaoImpl.save();
        return "Hello Ay...";
    }
}

Spring Boot多环境配置

一. 多环境配置的好处:

1.不同环境配置可以配置不同的参数~

2.便于部署,提高效率,减少出错~

二. properties多环境配置

  1. 配置激活选项

spring.profiles.active=dev ### 代表使用开发环境

2.添加其他配置文件

SpringBoot之整合其它热门技术详细总结

application.properties:

#激活哪一个环境的配置文件
spring.profiles.active=dev

Spring Boot集成Log4J

1)添加依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <exclusions>
                <!-- 排查默认日志包 -->
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
<!-- 引入log4j2依赖  start-->
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>
<!-- 引入log4j2依赖  end-->

2)application.properties添加

logging.config=classpath:log4j2.xml

3)resources文件夹下添加文件 log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />
        </Console>
    </Appenders>
    <Loggers>
        <Root level="debug">
            <AppenderRef ref="Console" />
        </Root>
    </Loggers>
</Configuration>

4)测试下

package com.example.log4j2.test;
import com.example.intellij.test.AyTestService;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by Ay on 2017/1/24.
 */
@RestController
@RequestMapping("/log4j2")
public class Log4JTestController {
    @Autowired
    private AyTestService ayTestService;
    Logger logger = LogManager.getLogger(this.getClass());

    @RequestMapping("/al")

    public String index2(){
        logger.info("method start");
        logger.equals("method start");
        return "Hello Ay...";
    }
}

Spring Boot事务控制

在Spring Boot中,当我们使用了spring-boot-starter-jdbc或spring-boot-starter-data-jpa依赖的时候,框 架会自动默认分别注入DataSourceTransactionManager或JpaTransactionManager。所以我们不需要任何额外 配置就可以用@Transactional注解进行事务的使用。

1)主要是@Transactional这个注解的使用

package com.example.transaction.test;
import com.example.intellij.test.AyTest;
import com.example.intellij.test.AyTestService;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.transaction.annotation.Isolation;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by Ay on 2017/1/24.
 */
@RestController
@RequestMapping("/transaction")

public class TransactionTestController {


    @Autowired
    private AyTestService ayTestService;


    @RequestMapping("/ay")
    @Transactional
    public String index() {
        AyTest ayTest = new AyTest();
        ayTest.setId("1");
        ayTest.setName("ay");

        AyTest ayTest2 = new AyTest();
        ayTest2.setId("2");
        ayTest2.setName("al & ay");

        AyTest ayTest3 = new AyTest();
        ayTest3.setId("3");
        ayTest3.setName("al");

        ayTestService.insert(ayTest);
        ayTestService.insert(ayTest2);
        //这边出现异常
        String s = null;
        s.split(",");

        ayTestService.insert(ayTest3);
        return "Hello Ay...";
    }
}

Spring Boot自定义错误页面

1)在resources/static文件夹下新建3个文件:401.html,404.html,500.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

我是一个漂亮的401

</body>
</html>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

我是一个漂亮的404

</body>
</html>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

我是一个漂亮的500

</body>
</html>

2)开发配置类

package com.example.errorpage.test;

import org.springframework.boot.context.embedded.ConfigurableEmbeddedServletContainer;
import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;
import org.springframework.boot.web.servlet.ErrorPage;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpStatus;

/**
 * Created by Ay on 2017/8/23.
 */
@Configuration
public class ErrorPageConfig {


    @Bean
    public EmbeddedServletContainerCustomizer containerCustomizer() {

        return new EmbeddedServletContainerCustomizer() {
            @Override
            public void customize(ConfigurableEmbeddedServletContainer container) {
                ErrorPage error401Page = new ErrorPage(HttpStatus.UNAUTHORIZED, "/401.html");
                ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, "/404.html");
                ErrorPage error500Page = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/500.html");
                container.addErrorPages(error401Page, error404Page, error500Page);
            }
        };
    }

}

Spring Boot运用打包发布

略,可看我录制的《一步一步学SpringBoot(二)》教学视频

Spring Boot使用Druid

Druid是Java语言中最好的数据库连接池,并且能够提供强大的监控和扩展功能。

第一步:添加依赖

<!-- druid start -->
<dependency>
   <groupId>com.alibaba</groupId>
   <artifactId>druid</artifactId>
   <version>1.0.18</version>
</dependency>

<!-- druid end -->

第二步:配置数据源相关信息

#mysql配置信息
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/test2
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
# 下面为连接池的补充设置,应用到上面所有数据源中
# 初始化大小,最小,最大
spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=20
# 配置获取连接等待超时的时间
spring.datasource.maxWait=60000
# 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒
spring.datasource.timeBetweenEvictionRunsMillis=60000
# 配置一个连接在池中最小生存的时间,单位是毫秒
spring.datasource.minEvictableIdleTimeMillis=300000
spring.datasource.validationQuery=SELECT 1 FROM DUAL
spring.datasource.testWhileIdle=true
spring.datasource.testOnBorrow=false
spring.datasource.testOnReturn=false
# 打开PSCache,并且指定每个连接上PSCache的大小
spring.datasource.poolPreparedStatements=true
spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
# 配置监控统计拦截的filters,去掉后监控界面sql无法统计,'wall'用于防火墙
spring.datasource.filters=stat,wall,log4j
# 通过connectProperties属性来打开mergeSql功能;慢SQL记录
spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
# 合并多个DruidDataSource的监控数据
#spring.datasource.useGlobalDataSourceStat=true

第三步:配置监控统计功能

package com.example.druid.test;

import com.alibaba.druid.support.http.WebStatFilter;

import javax.servlet.annotation.WebFilter;
import javax.servlet.annotation.WebInitParam;

/**
 * druid过滤器.
 * @author Administrator
 *
 */
@WebFilter(filterName="druidWebStatFilter",urlPatterns="/*",
        initParams={
                @WebInitParam(name="exclusions",value="*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*")// 忽略资源
        }
)
public class DruidStatFilter extends WebStatFilter {

}
package com.example.druid.test;

import com.alibaba.druid.support.http.StatViewServlet;

import javax.servlet.annotation.WebInitParam;
import javax.servlet.annotation.WebServlet;

/**
 * druid数据源状态监控.
 * @author Administrator
 *
 */

@WebServlet(urlPatterns="/druid/*",
        initParams={
                @WebInitParam(name="allow",value="192.168.1.72,127.0.0.1"),// IP白名单 (没有配置或者为空,则允许所有访问)
                @WebInitParam(name="deny",value="192.168.1.73"),// IP黑名单 (存在共同时,deny优先于allow)
                @WebInitParam(name="loginUsername",value="admin"),// 用户名
                @WebInitParam(name="loginPassword",value="123456"),// 密码
                @WebInitParam(name="resetEnable",value="false")// 禁用HTML页面上的“Reset All”功能
        }
)
public class DruidStatViewServlet extends StatViewServlet {
    private static final long serialVersionUID = 1L;

}

Spring Boot 使用Retry重试

1)引入pom文件

<!-- spring-retry start -->
<dependency>
   <groupId>org.springframework.retry</groupId>
   <artifactId>spring-retry</artifactId>
</dependency>
<dependency>
   <groupId>org.aspectj</groupId>
   <artifactId>aspectjweaver</artifactId>
</dependency>
<!-- spring-retry start -->

2)自定义一个简单异常

package com.example.retry.test;

/**
 * Created by Ay on 2017/8/22.
 */
public class BusinessException extends Exception{
}

3)服务类

package com.example.retry.test;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.retry.annotation.Backoff;
import org.springframework.retry.annotation.Recover;
import org.springframework.retry.annotation.Retryable;
import org.springframework.stereotype.Component;

@Component("remoteService")
public class RemoteService {

    private static final Logger logger = LoggerFactory.getLogger(RemoteService.class);

    @Retryable(value= {BusinessException.class},maxAttempts = 5,backoff = @Backoff(delay = 5000,multiplier = 2))
    public void call() throws Exception {
        logger.info("do something...");
        throw new BusinessException();
    }

    @Recover
    public void recover(BusinessException e) {
        //具体的业务逻辑
        logger.info(" ---------------------------  ");
        logger.info(e.getMessage());
    }
}

4)测试类

package com.example.retry.test;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/retry")
public class TestController {

    private static final Logger logger = LoggerFactory.getLogger(TestController.class);

    @Autowired
    private RemoteService remoteService;

    @RequestMapping("/test")
    public String login() throws Exception {
        remoteService.call();
        return String.valueOf("11");
    }
}

Spring Boot 整合 Spring Data

1)添加依赖

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

2)新建model和数据库表

package com.example.springdata.test;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

/**
 * 描述:
 * @author Ay
 * @date   2017/08/22
 */
@Entity
public class AyTest {

    @Id
    private String id;
    private String name;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

3)新建UserRepository

package com.example.springdata.test;

import org.springframework.data.repository.CrudRepository;

import java.util.List;

/**
 * @author  Ay
 * @date    2017/08/22
 */
public interface UserRepository extends CrudRepository<AyTest, String> {


    List<AyTest> findByIdAndName(String id, String name);

}

4)测试类

package com.example.springdata.test;

import com.example.intellij.test.Ay;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;
import java.util.UUID;

/**
 * Created by Ay on 2017/1/24.
 */
@RestController
@RequestMapping("/springdata")
public class SpringDataController {

    @Autowired
    private UserRepository userRepository;


    @RequestMapping("/test")
    public String index() {
        AyTest ayTest = new AyTest();
        ayTest.setId("60");
        ayTest.setName("ay and al");
        //select * from ay_test where id = '60' and name = "al"
        List<AyTest> ayTestList =  userRepository.findByIdAndName("60","ay and al");
        return "Hello Ay...";
    }


}

Spring Boot整合Websocket

【1】 http://www.cnblogs.com/bianzy/p/5822426.html

第一步:引入pom文件

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-websocket</artifactId>
   <version>1.3.5.RELEASE</version>
</dependency>

第二步:使用@ServerEndpoint创立websocket endpoint

首先要注入ServerEndpointExporter,这个bean会自动注册使用了@ServerEndpoint注解声明的Websocket endpoint。要注意,如果使用独立的servlet容器,而不是直接使用springboot的内置容器,就不要注入ServerEndpointExporter,因为它将由容器自己提供和管理

@Configuration
public class WebSocketConfig {
    @Bean
    public ServerEndpointExporter serverEndpointExporter() {
        return new ServerEndpointExporter();
    }

}

第三步:

@ServerEndpoint(value = "/websocket")
@Component
public class MyWebSocket {
    //静态变量,用来记录当前在线连接数。应该把它设计成线程安全的。
    private static int onlineCount = 0;

    //concurrent包的线程安全Set,用来存放每个客户端对应的MyWebSocket对象。
    private static CopyOnWriteArraySet<MyWebSocket> webSocketSet = new CopyOnWriteArraySet<MyWebSocket>();

    //与某个客户端的连接会话,需要通过它来给客户端发送数据
    private Session session;

    /**
     * 连接建立成功调用的方法*/
    @OnOpen
    public void onOpen(Session session) {
        this.session = session;
        webSocketSet.add(this);     //加入set中
        addOnlineCount();           //在线数加1
        System.out.println("有新连接加入!当前在线人数为" + getOnlineCount());
        try {
            sendMessage(CommonConstant.CURRENT_WANGING_NUMBER.toString());
        } catch (IOException e) {
            System.out.println("IO异常");
        }
    }

    /**
     * 连接关闭调用的方法
     */
    @OnClose
    public void onClose() {
        webSocketSet.remove(this);  //从set中删除
        subOnlineCount();           //在线数减1
        System.out.println("有一连接关闭!当前在线人数为" + getOnlineCount());
    }

    /**
     * 收到客户端消息后调用的方法
     *
     * @param message 客户端发送过来的消息*/
    @OnMessage
    public void onMessage(String message, Session session) {
        System.out.println("来自客户端的消息:" + message);

        //群发消息
        for (MyWebSocket item : webSocketSet) {
            try {
                item.sendMessage(message);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

    /**
     * 发生错误时调用
    @OnError
    public void onError(Session session, Throwable error) {
        System.out.println("发生错误");
        error.printStackTrace();
    }


    public void sendMessage(String message) throws IOException {
        this.session.getBasicRemote().sendText(message);
        //this.session.getAsyncRemote().sendText(message);
    }


    /**
     * 群发自定义消息
     * */
    public static void sendInfo(String message) throws IOException {
        for (MyWebSocket item : webSocketSet) {
            try {
                item.sendMessage(message);
            } catch (IOException e) {
                continue;
            }
        }
    }

    public static synchronized int getOnlineCount() {
        return onlineCount;
    }

    public static synchronized void addOnlineCount() {
        MyWebSocket.onlineCount++;
    }

    public static synchronized void subOnlineCount() {
        MyWebSocket.onlineCount--;
    }
}

第四步:

<!DOCTYPE HTML>
<html>
<head>
    <title>My WebSocket</title>
</head>

<body>
Welcome<br/>
<input id="text" type="text" /><button onclick="send()">Send</button>    <button onclick="closeWebSocket()">Close</button>
<div id="message">
</div>
</body>

<script type="text/javascript">
    var websocket = null;

    //判断当前浏览器是否支持WebSocket
    if('WebSocket' in window){
        websocket = new WebSocket("ws://localhost:8084/websocket");
    }
    else{
        alert('Not support websocket')
    }

    //连接发生错误的回调方法
    websocket.onerror = function(){
        setMessageInnerHTML("error");
    };

    //连接成功建立的回调方法
    websocket.onopen = function(event){
        setMessageInnerHTML("open");
    }

    //接收到消息的回调方法
    websocket.onmessage = function(event){
        setMessageInnerHTML(event.data);
    }

    //连接关闭的回调方法
    websocket.onclose = function(){
        setMessageInnerHTML("close");
    }

    //监听窗口关闭事件,当窗口关闭时,主动去关闭websocket连接,防止连接还没断开就关闭窗口,server端会抛异常。
    window.onbeforeunload = function(){
        websocket.close();
    }

    //将消息显示在网页上
    function setMessageInnerHTML(innerHTML){
        document.getElementById('message').innerHTML += innerHTML + '<br/>';
    }

    //关闭连接
    function closeWebSocket(){
        websocket.close();
    }

    //发送消息
    function send(){
        var message = document.getElementById('text').value;
        websocket.send(message);
    }
</script>
</html>

  • 这种距离不是要打架就是要接吻。
  • 美丽的地方,都有故事。

经典故事

有个老人在河边钓鱼,一个小孩走过去看他钓鱼,老人技巧纯熟,所以没多久就钓上了满篓的鱼,老人见小孩很可爱,要把整篓的鱼送给他,小孩摇摇头,老人惊异的问道:「你为何不要?」小孩回答:「我想要你手中的钓竿。」老人问:「你要钓竿做什么?」小孩说:「这篓鱼没多久就吃完了,要是我有钓竿,我就可以自己钓,一辈子也吃不完。」

我想你一定会说:好聪明的小孩。错了,他如果只要钓竿,那他一条鱼也吃不到。因为,他不懂钓鱼的技巧,光有鱼竿是没用的,因为钓鱼重要的不在“钓竿”,而在“钓技”。

[有太多人认为自己拥有了人生道上的钓竿,再也无惧于路上的风雨,如此,难免会跌倒于泥泞地上。就如小孩看老人,以为只要有钓竿就有吃不完的鱼,像职员看老板,以为只要坐在办公室,就有滚进的财源。]
