本文主要是介绍Security之会话篇,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
1、功能实现
1.session 超时失效
2.session 并发失效
3.手动清除孤立 session
4.整合redis实现session共享(集群)
2、security06 子工程

3、自定义会话无效策略、会话过期策略
package com.yzm.security06.config;import lombok.extern.slf4j.Slf4j;
import org.springframework.security.web.session.InvalidSessionStrategy;import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;/*** 默认session超时失效*/
@Slf4j
public class SecSessionInvalidStrategy implements InvalidSessionStrategy {private final boolean createNewSession;public SecSessionInvalidStrategy() {this.createNewSession = true;}public SecSessionInvalidStrategy(boolean createNewSession) {this.createNewSession = createNewSession;}@Overridepublic void onInvalidSessionDetected(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {log.info("Session 超时失效");if (this.createNewSession) {request.getSession();}response.sendRedirect(request.getContextPath() + "/auth/login?invalid");}}
package com.yzm.security06.config;import lombok.extern.slf4j.Slf4j;
import org.springframework.security.web.session.SessionInformationExpiredEvent;
import org.springframework.security.web.session.SessionInformationExpiredStrategy;import java.io.IOException;/*** 并发登录导致session失效*/
@Slf4j
public class SecSessionExpiredStrategy implements SessionInformationExpiredStrategy {@Overridepublic void onExpiredSessionDetected(SessionInformationExpiredEvent event) throws IOException {log.info("session 并发失效");// 跳转html页面event.getResponse().sendRedirect(event.getRequest().getContextPath() + "/auth/login?expired");}}
4、SecurityConfig 配置类
package com.yzm.security06.config;import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
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;
import org.springframework.security.core.session.SessionRegistry;
import org.springframework.security.core.session.SessionRegistryImpl;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.access.expression.DefaultWebSecurityExpressionHandler;import javax.sql.DataSource;@Slf4j
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {private final UserDetailsService userDetailsService;private final SecPermissionEvaluator permissionEvaluator;public SecurityConfig(@Qualifier("secUserDetailsServiceImpl") UserDetailsService userDetailsService, SecPermissionEvaluator permissionEvaluator) {this.userDetailsService = userDetailsService;this.permissionEvaluator = permissionEvaluator;}/*** 密码编码器* passwordEncoder.encode是用来加密的,passwordEncoder.matches是用来解密的*/@Beanpublic PasswordEncoder passwordEncoder() {return new BCryptPasswordEncoder();}/*** 注入自定义PermissionEvaluator*/@Beanpublic DefaultWebSecurityExpressionHandler webSecurityExpressionHandler() {DefaultWebSecurityExpressionHandler handler = new DefaultWebSecurityExpressionHandler();handler.setPermissionEvaluator(permissionEvaluator);return handler;}/*** session 管理*/@Beanpublic SessionRegistry sessionRegistry() {return new SessionRegistryImpl();}/*** 配置用户* 指定默认从哪里获取认证用户的信息,即指定一个UserDetailsService接口的实现类*/@Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {// 从数据库读取用户、并使用密码编码器解密auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());}//配置资源权限规则@Overrideprotected void configure(HttpSecurity http) throws Exception {http// 关闭CSRF跨域.csrf().disable()// 登录.formLogin().loginPage("/auth/login") //指定登录页的路径,默认/login.loginProcessingUrl("/login") //指定自定义form表单请求的路径(必须跟login.html中的form action=“url”一致).defaultSuccessUrl("/home", true) // 登录成功后的跳转url地址.failureUrl("/auth/login?error") // 登录失败后的跳转url地址.permitAll().and()// 记住我.rememberMe().tokenValiditySeconds(120) // 有效时间,单位秒,默认30分钟.and().exceptionHandling().accessDeniedPage("/401") // 拒接访问跳转页面.and()// 退出登录.logout().permitAll().and()// 访问路径URL的授权策略,如注册、登录免登录认证等.authorizeRequests().antMatchers("/", "/home", "/register", "/auth/login").permitAll() //指定url放行.anyRequest().authenticated() //其他任何请求都需要身份认证.and()// session 管理.sessionManagement()// 1.session 超时,默认60秒,即60秒内无操作就会过期// 通过在yml里面设置 server.servlet.session.timeout=60//.invalidSessionUrl("/invalid").invalidSessionStrategy(new SecSessionInvalidStrategy())// 2.session 并发控制:控制一个账号同一时刻最多能登录多少个.maximumSessions(1) // 限制最大登陆数// 当达到最大值时,是否阻止用户登录,false表示不阻止,那么新的会覆盖旧的,旧的被迫下载.maxSessionsPreventsLogin(false)//.expiredUrl("/invalid").expiredSessionStrategy(new SecSessionExpiredStrategy()) // 当达到最大值时,旧用户被踢出后的操作// 3.手动使Session立即失效.sessionRegistry(sessionRegistry());}
}
login.thml
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org">
<head><meta charset="UTF-8"><title>登录页</title>
</head>
<body>
<h1 th:if="${param.logout}">You have been logged out.</h1>
<h1 th:if="${param.error}">You username or password is wrong.</h1>
<h1 th:if="${param.invalid}">Session invalid.</h1>
<h1 th:if="${param.expired}">Session expired.</h1><h2>用户名密码登录</h2>
<form action="/login" method="post"><p><label for="username">Username</label><input type="text" id="username" name="username" placeholder="Username"></p><p><label for="password">Password</label><input type="password" id="password" name="password" placeholder="Password"></p><p><label><input type="checkbox" name="remember-me"></label> Remember me on this computer.</p><button type="submit">Sign in</button>
</form>
<script type="text/javascript">function kickOut() {const href = location.href;if (href.indexOf("expired") > 0) {alert("您的账号在另一台设备上登录,如非本人操作,请立即修改密码!");}}window.onload = kickOut();
</script>
</body>
</html>
5、超时失效测试
默认超时时间60秒
server:servlet:session:timeout: 60
登录yzm,停留时间超过一分钟,刷新一下
6、并发失效
需要2个浏览器,先用谷歌登录yzm,再用其他浏览器登录yzm后,刷新谷歌浏览器
7、测试手动清除session
在SecurityConfig注入
/*** 会话注册表*/@Beanpublic SessionRegistry sessionRegistry() {return new SessionRegistryImpl();}// session 管理.sessionManagement()...// 3.手动使Session立即失效.sessionRegistry(sessionRegistry())
在HomeController中添加接口
...@Controller
public class HomeController {private final UserService userService;private final PasswordEncoder passwordEncoder;private final SessionRegistry sessionRegistry;public HomeController(UserService userService, PasswordEncoder passwordEncoder,SessionRegistry sessionRegistry) {this.userService = userService;this.passwordEncoder = passwordEncoder;this.sessionRegistry = sessionRegistry;}...@GetMapping("/kick")@ResponseBodypublic String removeUserSessionByUsername(@RequestParam String username) {int count = 0;// 获取session中所有的用户信息List<Object> users = sessionRegistry.getAllPrincipals(); // 获取所有 principal 信息for (Object principal : users) {if (principal instanceof UserDetails) {String principalName = ((UserDetails) principal).getUsername();if (principalName.equals(username)) {// 参数二:是否包含过期的SessionList<SessionInformation> sessionsInfo = sessionRegistry.getAllSessions(principal, false);if (null != sessionsInfo && sessionsInfo.size() > 0) {for (SessionInformation sessionInformation : sessionsInfo) {// 使 session 过期sessionInformation.expireNow();count++;}}}}}return "操作成功,清理session共" + count + "个";}
}
谷歌登录yzm 再用其他浏览器登录admin管理员
访问/kick?username=yzm,yzm被踢下线
8、session共享(集群)
引入依赖
<!-- session-redis --><dependency><groupId>org.springframework.session</groupId><artifactId>spring-session-data-redis</artifactId></dependency><!-- redis支持 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency>
配置redis
spring:datasource:driver-class-name: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://127.0.0.1:3306/test04?useUnicode=true&characterEncoding=utf8&useSSL=false&allowMultiQueries=true&zeroDateTimeBehavior=convertToNull&serverTimezone=Asia/Shanghaiusername: rootpassword: rootmain:allow-bean-definition-overriding: trueredis:host: 127.0.0.1port: 6379password: 1234database: 0
在SecurityConfig 启用 redis 管理 session
配置了maxInactiveIntervalInSeconds = 200之后,这个server.servlet.session.timeout=60就无效了
@Slf4j
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
@EnableRedisHttpSession(redisNamespace = "spring:session:yzm", maxInactiveIntervalInSeconds = 200, flushMode = FlushMode.ON_SAVE)
public class SecurityConfig extends WebSecurityConfigurerAdapter {...}
注释session注册表,手动清除session功能不可用
/*** 会话注册表*/
// @Bean
// public SessionRegistry sessionRegistry() {
// return new SessionRegistryImpl();
// }/*** 是spring session为Spring Security提供的,* 用于在集群环境下控制会话并发的会话注册表实现*/@Autowired@Lazyprivate FindByIndexNameSessionRepository<? extends Session> sessionRepository;@Beanpublic SpringSessionBackedSessionRegistry sessionRegistry(){return new SpringSessionBackedSessionRegistry<>(sessionRepository);}
启动端口8080、8090;火狐8080登录yzm,谷歌8090再次登录yzm,刷新火狐yzm
