 其它代码照旧 
 
+
+<!------------- tab:SpringSecurity ------------->
+
+（结合上部分，同时做到集成 Redis + 前后端分离）
+
+1、`pom.xml` 引入依赖 
+``` xml
+<!-- HttpSession 存储到 Redis -->
+<dependency>
+	<groupId>org.springframework.session</groupId>
+	<artifactId>spring-session-data-redis</artifactId>
+</dependency>
+<dependency>
+	<groupId>org.springframework.boot</groupId>
+	<artifactId>spring-boot-starter-data-redis</artifactId>
+</dependency>
+```
+
+2、`yml` 增加配置
+``` yml
+spring:
+    session:
+        store-type: redis
+        timeout: 8H
+        redis:
+            namespace: spring:session
+
+    data:
+        # redis配置
+        redis:
+            # Redis数据库索引（默认为0）
+            database: 3
+            # Redis服务器地址
+            host: 127.0.0.1
+            # Redis服务器连接端口
+            port: 6379
+            # Redis服务器连接密码（默认为空）
+            password:
+            # 连接超时时间
+            timeout: 10s
+            lettuce:
+                pool:
+                    # 连接池最大连接数
+                    max-active: 200
+                    # 连接池最大阻塞等待时间（使用负值表示没有限制）
+                    max-wait: -1ms
+                    # 连接池中的最大空闲连接
+                    max-idle: 10
+                    # 连接池中的最小空闲连接
+                    min-idle: 0
+```
+
+3、在 `CustomAccessDeniedHandler` 自定义认证异常处理类中，返回 `json` 格式数据
+
+``` java
+@Component
+public class CustomAccessDeniedHandler implements AccessDeniedHandler, AuthenticationEntryPoint, Serializable {
+
+    // 未登录异常
+    @Override
+    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws IOException {
+        //验证为未登陆状态会进入此方法，认证错误
+        response.setStatus(401);
+        response.setCharacterEncoding("UTF-8");
+        response.setContentType("application/json; charset=utf-8");
+        PrintWriter printWriter = response.getWriter();
+        String body = new ObjectMapper().writeValueAsString(AjaxJson.get(401, "请先进行登录"));
+        printWriter.write(body);
+        printWriter.flush();
+    }
+
+    // 权限不足
+    @Override
+    public void handle(HttpServletRequest request, HttpServletResponse response, AccessDeniedException accessDeniedException) throws IOException {
+        // 登陆状态下，权限不足执行该方法
+        response.setStatus(200);
+        response.setCharacterEncoding("UTF-8");
+        response.setContentType("application/json; charset=utf-8");
+        PrintWriter printWriter = response.getWriter();
+        String body = new ObjectMapper().writeValueAsString(AjaxJson.get(403, "权限不足"));
+        printWriter.write(body);
+        printWriter.flush();
+    }
+    
+}
+```
+
+4、别忘了注入到 `SecurityFilterChain` 过滤器链 
+``` java
+ // 异常处理
+httpSecurity.exceptionHandling(httpSecurityExceptionHandlingConfigurer -> {
+	// 权限不足处理方案
+	httpSecurityExceptionHandlingConfigurer.accessDeniedHandler(accessDeniedHandler);
+	// 未登录 处理逻辑
+	httpSecurityExceptionHandlingConfigurer.authenticationEntryPoint(accessDeniedHandler);
+});
+```
+
+5、在登录时，返回对应 token 信息
+``` java
+// 测试登录 
+@RequestMapping("doLogin")
+public AjaxJson doLogin(String username, String password, HttpServletRequest request) {
+	try {
+		// 验证账号密码
+		UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = new UsernamePasswordAuthenticationToken(username, password);
+		usernamePasswordAuthenticationToken.setDetails(sysUserDao.findByUsername(username));
+		Authentication authentication = authenticationManager.authenticate(usernamePasswordAuthenticationToken);
+		// 存入上下文
+		SecurityContextHolder.getContext().setAuthentication(authentication);
+		request.getSession().setAttribute(HttpSessionSecurityContextRepository.SPRING_SECURITY_CONTEXT_KEY, SecurityContextHolder.getContext());
+		// 返回
+		String token = request.getSession().getId();
+		return AjaxJson.getSuccess("登录成功!").set("token", token);
+	} catch (Exception e) {
+		e.printStackTrace();
+		return AjaxJson.getError(e.getMessage());
+	}
+}
+```
+
+6、前端改造
+- 1、在登录请求时，将返回的 token 保存到本地 `localStorage.setItem('token', res.token)`。
+- 2、在后续每次请求中，读取本地保存的 token 塞到请求 header 中
+
+``` js
+const header = {};
+if(localStorage.token) {
+	header.token = localStorage.token;
+}
+// 后续提交请求...
+```
+
+7、新建 `HttpSessionConfigure` 配置重写 `HttpSessionId` 读取策略，改为从 `header` 头读取 `token` 参数作为 `SessionId`
+``` java
+@Configuration
+public class HttpSessionConfigure {
+    // HttpSession 读取策略，从 header 头读取 token 参数作为 session id
+    @Bean
+    public HeaderHttpSessionIdResolver httpSessionStrategy() {
+        System.out.println("----------------- 自定义 HttpSession Id 读取方式");
+        return new HeaderHttpSessionIdResolver("token");
+    }
+}
+```
+
