Spring Security（三）
SpringSecurity整合SpringBoot集中式版本
技术选型
- SpringBoot 2.1.3
- SpringSecurity
- MySQL 5.7
- Mybatis
- JSP
初步整合认证第一版
创建工程并导入jar包
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.3.RELEASE</version>
<relativePath/>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
编写控制器
package com.weiwei.xu.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
@RequestMapping(value = "/product")
public class ProductController {
@RequestMapping(value = "/findAll")
@ResponseBody
public String findAll(){
return "success";
}
}
编写启动类
package com.weiwei.xu;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringBootSecurityApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootSecurityApplication.class, args);
}
}
测试
- 输入： http://localhost :8080/product/findAll。
加入SpringSecurity的jar包
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
重启测试
- SpringBoot已经为SpringSecurity提供了默认配置，默认所有的资源都必须认证通过之后才能访问。
- SpringBoot已经提供了默认的用户名user，密码在项目启动的时候随机生成，如下图所示：
- 认证通过之后就可以继续访问处理器资源：

初步整合认证第二版
说明
- SpringBoot官方是不推荐在SpringBoot中使用JSP的，但是SpringBoot是可以使用JSP作为模板引擎的，本项目采用JSP作为前端展示页面。
导入SpringBoot的tomcat启动插件jar包
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
加入JSP页面等静态资源
- 如果在src/main目录下没有webapp目录，那么就创建webapp目录，并且手动将Java工程改为web工程。
- 如果webapp目录，和下图的类似，就可以用了。
- 导入静态资源，注意WEB-INF就不用了。
提供SpringSecurity的配置类
package com.weiwei.xu.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
/**

@Configuration
@EnableWebSecurity
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {
/**
* 认证用户的来源[内存或数据库]
*
* @param auth
* @throws Exception
*/
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().withUser("user").password("{noop}123456").roles("USER");
}
/**
* SpringSecurity相关信息
*
* @param http
* @throws Exception
*/
@Override
protected void configure(HttpSecurity http) throws Exception {
//释放静态资源，指定资源拦截规则，指定自定义认证页面，指定退出认证配置，csrf配置
http.authorizeRequests().antMatchers("/login.jsp","/failer.jsp","/css/**","/img/**","/pages/**").permitAll()
.antMatchers("/**").access("hasAnyRole('USER','ADMIN')")
.anyRequest()
.authenticated()
.and()
.formLogin().loginPage("/login.jsp").loginProcessingUrl("/login").successForwardUrl("/index.jsp").failureForwardUrl("/failer.jsp").permitAll()
.and()
.logout().logoutUrl("/logout").logoutSuccessUrl("/login.jsp")
.invalidateHttpSession(true) //清空session
.permitAll();
}
}
修改启动类
package com.weiwei.xu;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
/**

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class})
public class SpringBootSecurityApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(SpringBootSecurityApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SpringBootSecurityApplication.class);
}
}

.and()
.logout().logoutUrl("/logout").logoutSuccessUrl("/login.jsp")
.invalidateHttpSession(true) //清空session

}
}
- 在启动类上开启方法级的授权注解：

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;

@MapperScan("com.weiwei.xu.mapper")
@SpringBootApplication
@EnableGlobalMethodSecurity(securedEnabled = true)
public class SpringBootSecurityApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(SpringBootSecurityApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SpringBootSecurityApplication.class);
}
}
- 在产品处理器上添加注解：
package com.weiwei.xu.controller;
import org.springframework.security.access.annotation.Secured;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping(value = "/product")
public class ProductController {
@RequestMapping(value = "/findAll")
@Secured({"ROLE_PRODUCT","ROLE_ADMIN"})
public String findAll(){
return "product-list";
}
}
处理403异常和其它异常
package com.weiwei.xu.exception;
import org.springframework.security.acls.model.NotFoundException;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import java.nio.file.AccessDeniedException;
@ControllerAdvice
public class SecurityExceptionHandler {
@ExceptionHandler(value = AccessDeniedException.class)
public String handle403Exception(){
return "redirect:403";
}
@ExceptionHandler(value = RuntimeException.class)
public String handle500Exception(){
return "redirect:500";
}
@ExceptionHandler(value = NotFoundException.class)
public String handle404Exception(){
return "redirect:404";
}
}

- 初步整合认证第三版
SpringSecurity整合SpringBoot分布式版本
分布式认证概念说明
- 分布式认证，即我们常说的单点登录，简称SSO，指的是在多应用系统的项目中，用户只需要登录一次，就可以访问所有互相信任的应用系统。
分布式认证流程图
- 在分布式项目中，每台服务器都有各自独立的session，而这些session之间是无法直接共享资源的，所以，session通常不能作为单点登录的解决方案。
- 最合理的单点登录方案流程如下图所示：
-
总结，单点登录要实现的两大环节：
- ①用户认证：用户向认证服务器发起认证请求，认证服务器给用户返回一个成功的令牌token，主要在认证服务器中完成，认证服务器只有一个。
- ②身份校验：用户携带token去访问其他服务器时，在其他服务器中药对token的真伪进行校验，主要在资源服务器中完成，资源服务器可以有多个。
JWT介绍
概念说明
- 从分布式认证流程中，我不难发现，这中间起最关键作用的就是token，token的安全与否，直接关系到系统的健壮性，这里我们选择使用jwt来实现token的生成和校验。
- jwt，全程JSON Web Token， 官网地址 ，是一款出色的分布式身份校验方案。可以生成token，也可以解析校验token。
-
JWT生成的token由以下三部分组成：
- 头部：主要设置一些规范信息，签名部分的编码格式就在头部中声明。
- 载荷：token中存放有效信息的部分，比如用户名、用户角色、过期时间等，但是不要放密码，会泄露！
- 签名：将头部和载荷分别采用base64编码后，用“.”相连，再加入盐，最后使用头部声明的编码类型进行编码，就得到了签名。
JWT生成的token的安全性分析
- 从JWT生成的token组成上来看，要想避免token被伪造，主要就看签名部分了，而签名部分又有三部分组成，其中头部和载荷的base编码，几乎是透明的，毫无安全性可言，那么最终守护token安全的重担就落在了加入盐上面了。
- 如果生成token所用的盐和解析token所加入的盐是一样的，那后果将不堪设想，大家都可以使用这个盐来解析token，用来伪造token。
- 这时，就需要对盐采用非对称加密的方式进行加密，以达到生成token和校验token时所用的盐不一致的安全效果。
非对称机密RSA介绍
-
基本原理：同时生成两把密钥：私钥和公钥，私钥隐藏保存，公钥可以发给信任客户端。
- 私钥加密，持有私钥或公钥才可以解密。
- 公钥加密，持有私钥才可以解密。
- 优点：安全，难以破解。
- 缺点：算法比较耗时，为了安全，可以接受。
- 历史：三位数学家Rivest、Shamir和Adleman设计了一种算法，可以实现非对称加密。这种算法用他们三个人的名字缩写：RSA。
SpringSecurity+JWT+RSA分布式认证思路分析
SpringSecurity主要是通过过滤器来实现功能的，所以我们需要找到SpringSecurity实现认证和校验身份的过滤器。
回顾集中式认证流程
-
用户认证：
- 使用UsernamePasswordAuthenticationFilter过滤器中的attemptAuthentication方法实现认证功能，该过滤器父类中的successfulAuthentication方法实现认证成功后的操作。
-
身份校验：
- 使用BasicAuthenticationFilter过滤器中的doFilterInternal方法验证是否登录，以决定能否进入后续过滤器。
分布式认证流程
-
用户认证：
- 由于，分布式项目，多数是前后端分离的架构设计，我们要满足可以接受异步POST的认证请求参数，需要修改UsernamePasswordAuthenticationFilter过滤器中的attemptAuthentication方法，让其能够接受请求体。另外，默认的successfulAuthentication方法在认证通过后，是把用户信息直接放入到session中就完事了，现在我们需要修改这个方法，在认证通过后生成token并返回给用户。
-
身份认证：
- 原来BasicAuthenticationFilter过滤器中的doFilterInternal方法校验用户是否登录，就是看session中是否有用户信息，我们需要修改为，验证用户携带的token是否合法，并解析出用户信息，交给SpringSecurity，以便后续的授权功能可以正常使用。
