IDEA之Maven搭建Spring4 SpringMVC4 Mybatis3

首先打开Mysql的图形界面工具进行建库建表,当然也可以使用cmd黑窗口命令形式进行建库建表。

create database kaoshi;
use kaoshi;

create table k_dept(
   id int(11) auto_increment primary key,
   name varchar(30),
   age int(11),
   birdate date);

INSERT INTO `k_dept` VALUES ('1', '张三', '56', '2017-08-07');
INSERT INTO `k_dept` VALUES ('2', '李四', '47', '2017-09-04');
INSERT INTO `k_dept` VALUES ('3', '王五', '36', '2017-09-05');
IDEA之Maven搭建Spring4 SpringMVC4 Mybatis3

打开IDEA,创建Maven项目。

先把配置文件整理好。 db.properties。位置在resources目录下。

initialPoolSize=100
acquireIncrement=5
maxPoolSize=500

日志记录配置文件,log4j.properties。

log4j.appender.E.MaxFileSize = 50MB

spring-mvc.xml 。位置在resources目录下。

<?xml version="1.0" encoding="UTF-8"?>

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

而后是 spring-mybatis.xml。位置同上。

        <property name="mapperLocations">
            <list>
                <value>classpath*:com/zhenqi/dao/*.xml</value>
            </list>
        </property>
    </bean>

    <!-- Mapper接口所在包名,Spring会自动查找其下的Mapper -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"

        <aop:advisor advice-ref="txAdvice" pointcut-ref="allManagerMethod" />
    </aop:config>

</beans>

然后在 web.xml 文件配置。

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

    </context-param>

        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

        <servlet-name>springmvc-dispatcherservlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

配置文件整理好了,接下来就可以编写Java代码了。

1、Entity实体对象Dept.java

package com.zhenqi.entity;

import java.util.Date;

/**
 * Created by wuming on 2017/9/8.
 */
public class Dept {
    private Integer id;
    private String name;
    private Integer age;
    private Date birDate;

    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
    public Date getBirDate() {
        return birDate;
    }
    public void setBirDate(Date birDate) {
        this.birDate = birDate;
    }
}
2、Dao层

而后是Dao接口与Mapper xml文件。

DeptDao.java

package com.zhenqi.dao;
import com.zhenqi.entity.Dept;
import java.util.List;
/**
 * Created by wuming on 2017/9/8.
 */
public interface DeptDao {
    //查找所有内容
    public List<Dept> findAll();
}

Dept.xml 其位置 com/zhenqi/dao目录下。

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.zhenqi.dao.DeptDao">

    <resultMap id="deptAll" type="com.zhenqi.entity.Dept" >
        <id property="id" column="IID" />
        <result property="name" column="name" />
        <result property="age" column="age" />
        <result property="birDate" column="birdate" />
    </resultMap>
    <!-- 查找 -->
    <select id="findAll"  resultMap="deptAll">
        select * from k_dept
    </select>
</mapper>

3.Service层,也就是处理业务相关的。DeptService.java接口文件如下:

package com.zhenqi.service;
import com.zhenqi.entity.Dept;
import java.util.List;
/**
 * Created by wuming on 2017/9/8.
 */
public interface DeptService {
    //查找所有内容
    public List<Dept> findall();
}

实现类 DeptServiceImpl.java 如下:

package com.zhenqi.service.impl;

import com.zhenqi.dao.DeptDao;
import com.zhenqi.entity.Dept;
import com.zhenqi.service.DeptService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * Created by wuming on 2017/9/8.
 */

@Service("deptService")
public class DeptServiceImpl implements DeptService {
    //注入dao对象
    @Autowired
    private DeptDao deptDao;

    public List<Dept> findall() {
        return deptDao.findAll();
    }
}

4、Controller层,也就是所谓的控制层。DeptController.java文件如下:

package com.zhenqi.controller;

import com.zhenqi.entity.Dept;
import com.zhenqi.service.DeptService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
import java.util.List;

/**
 * Created by wuming on 2017/9/8.
 */
@Controller
@RequestMapping("/dept")
public class DeptController {

    @Autowired
    private DeptService deptService;

    @RequestMapping("/find")
    public String find(ModelMap model, HttpServletRequest request){
        List<Dept> deptList=deptService.findall();
        //将获取到的数据存入ModelMap中,以便页面取出
        model.addAttribute("depts", deptList);
        return "dept";
    }
}

5、view层,就是jsp或html。dept.jsp文件如下,其位置在 WEB-INF/views/ 目录下。

<%@ page language="java" contentType="text/html; charset=UTF-8"
         pageEncoding="UTF-8"%>
<%@ page  isELIgnored="false"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Dept</title>
</head>
<body>
<table>
    <tr>
        <th>ID</th>
        <th>姓名</th>
        <th>年龄</th>
        <th>生日</th>
    </tr>
    <c:forEach var="dept" items="${depts}">
        <tr>
            <td><c:out value="${dept.id}"/></td>
            <td><c:out value="${dept.name}"/></td>
            <td><c:out value="${dept.age}"/></td>
            <td><c:out value="${dept.birDate}"/></td>
        </tr>
    </c:forEach>
</table>
</body>
</html>

启动Tomcat容器,如果不知怎么在IDEA中部署maven项目到Tomcat上的朋友,可参考文章: IDEA运行Maven项目部署tomcat
