通过shiro框架记录用户登录，登出及浏览器关闭日志-编程知识

背景：

公司项目之前使用websocket记录用户登录登出日志及浏览器关闭记录用户登出日志，测试发现仍然存在问题，

问题一：当浏览器每次刷新时websocket其实是会断开重新连接的，因此刷新一下就触发记录登出的日志，其实用户并没有真正退出，

问题二：websocket需要配置，如果线上可能要使用wss等相关nginx都需要运维维护，不熟悉的运维还搞不定，

因此领导要求不要用websocket直接使用shiro不用任何配置，下面是改造后的代码逻辑

第一步：添加创建自定义退出过滤器并发布退出事件

public class CustomLogoutFilter extends LogoutFilter{
   private static final Logger log = LoggerFactory.getLogger(CustomLogoutFilter.class);
   private ApplicationEventPublisher eventPublisher;
   public CustomLogoutFilter(ApplicationEventPublisher eventPublisher) {
   this.eventPublisher = eventPublisher;
   }
@Override
public boolean preHandle(ServletRequest request, ServletResponse response) throws Exception {
eventPublisher.publishEvent(new LogoutEvent(this, request, response));
return super.preHandle(request, response);
}
}

第二步：创建退出监听事件

注”使用监听事件主要是想让代码做到分离，由于项目代码结构的原因，结构简单的可以直接在过滤器中记录日志也没有任何问题

public class LogoutEvent extends ApplicationEvent{
private static final long serialVersionUID = -8347909954763768519L;
private ServletRequest request;
private ServletResponse response;

public LogoutEvent(Object source, ServletRequest request, ServletResponse response) {
super(source);
this.request = request;
this.response = response;
}

#set,get 省略
}

第三步：将过滤器注入到shiro的配置中

这样当用户退出时就会执行自定义退出过滤器中的方法。

@Configuration
public class ShiroCommonConfig{
static final Logger logger=LoggerFactory.getLogger(ShiroCommonConfig.class);

@Bean
ShiroSessionFactory sessionFactory() {
return new ShiroSessionFactory();
}

//过滤器退出路径配置
@Bean
CustomLogoutFilter logoutFilter(ApplicationEventPublisher eventPublisher) {
String adminPath = Global.getConfig(KeyConsts.ADMIN_PATH) == null ? DefaultValueConsts.DEFAULT_ADMIN_PATH : Global.getConfig(KeyConsts.ADMIN_PATH);
CustomLogoutFilter logoutFilter = new CustomLogoutFilter(eventPublisher);
//重定向到登录页
logoutFilter.setRedirectUrl(adminPath + "/login");
return logoutFilter;
}

}

第四步：创建退出事件监听器记录退出日志

/***
* @author wxy
* @ desc修复之前使用aop时AllModulesAspect切入不到退出的方法从而记录不到用户退出日志
* @date 20230731
*/
@Component
public class LogoutEventListener implements ApplicationListener<LogoutEvent>{

   @Override
   public void onApplicationEvent(LogoutEvent event) {
       Subject subject=SecurityUtils.getSubject();
       Session loginSession = subject.getSession();
       ServletRequest servletRequest =event.getRequest();
       HttpServletRequest httpServletRequest = (HttpServletRequest) servletRequest;
   String username=(String)loginSession.getAttribute("username_");
       String staffName=(String)loginSession.getAttribute("staffName_");
       String userKind=(String)loginSession.getAttribute("systemUser_");
       String userId=(String)loginSession.getAttribute("userid_");
       String path =servletRequest.getServletContext().getContextPath();
       String ip =httpServletRequest.getRemoteAddr();
       String loginType = Constants.LOGOUTMODEL;
   String loginTitle = Constants.LOGINDESIGNERTITLE;
   String sessionId =loginSession.getId().toString();
   Map<String,String> params = new HashMap<String,String>();
   params.put("userId", userId);
   params.put("username", username);
   params.put("staffName", staffName);
   params.put("ip", ip);
   params.put("loginType", loginType);
   params.put("sessionId", sessionId);
   params.put("loginTitle", loginTitle);

       if(StringUtils.isNoneEmpty(path) && path.contains(Constants.CONTEXT_DESIGNER_NAME)) {
           //处理存储存数据库的代码逻辑
           CommonLogUtils.saveLog(params);
           //处理存es的代码逻辑
           handlerLogSaveEs(username,staffName,userKind,userId,httpServletRequest);
       }
   }
}

第五步：创建登录监听事件

public class LoginSuccessEvent extends ApplicationEvent{
private static final long serialVersionUID = 3055102020280674571L;
private ServletRequest request;
private ServletResponse response;

public LoginSuccessEvent(Object source, ServletRequest request, ServletResponse response) {
super(source);
this.request = request;
this.response = response;
}
}

第六步：创建自定义过滤器并登录成功时发布事件

@Component
public class FormAuthenticationFilter extends org.apache.shiro.web.filter.authc.FormAuthenticationFilter {
   @Autowired
   private ApplicationEventPublisher eventPublisher;

   protected boolean onLoginSuccess(AuthenticationToken token, Subject subject,
ServletRequest request, ServletResponse response) throws Exception {
       eventPublisher.publishEvent(new LoginSuccessEvent(this, request, response));
           issueSuccessRedirect(request, response);
           return false;
}
}

第七步：创建登录成功的监听器记录登录日志

@Component
public class LogSuccessEventListener implements ApplicationListener<LoginSuccessEvent>{

   @Override
   public void onApplicationEvent(LoginSuccessEvent event) {
       Subject subject=SecurityUtils.getSubject();
       Session loginSession = subject.getSession();
       ServletRequest servletRequest =event.getRequest();
       String sessionId =loginSession.getId().toString();
       HttpServletRequest httpServletRequest = (HttpServletRequest) servletRequest;
       String username =(String)loginSession.getAttribute("username_");
   String userId =(String)loginSession.getAttribute("userid_");
   String staffName_ =(String)loginSession.getAttribute("staffName_");
       String path =servletRequest.getServletContext().getContextPath();
       String ip =httpServletRequest.getRemoteAddr();
       String loginType = Constants.LOGINMODEL;
   String loginTitle = Constants.LOGINDESIGNERTITLE;
   Map<String,String> params = new HashMap<String,String>();
   params.put("userId", userId);
   params.put("username", username);
   params.put("staffName", staffName_);
   params.put("ip", ip);
   params.put("loginType", loginType);
   params.put("sessionId", sessionId);
   params.put("loginTitle", loginTitle);
   //登录成功后在session对象中放入ip及contextPath名称处理无请求时会话过期
   loginSession.setAttribute("ip", ip);
   loginSession.setAttribute("contextPath", path);
   loginSession.setAttribute("successFlag", "true");
   //保存到数据库
       if(StringUtils.isNoneEmpty(path) && path.contains(Constants.CONTEXT_DESIGNER_NAME)) {
           CommonLogUtils.saveLog(params); ##调用自己的登录接口逻辑
       }
   }

}

第八步：创建会话过期监听记录浏览器关闭时，回话过期记录退出日志

import org.apache.shiro.session.Session;
import org.apache.shiro.session.SessionListener;

public class SessionExpireClearListener implements SessionListener {
   private Logger Logger = LoggerFactory.getLogger(SessionExpireClearListener.class);

@SuppressWarnings("unchecked")
   @Override
   public void onStart(Session session) {
       Logger.debug("session创建:id为 {}", session.getId());
   }

   @Override
   public void onStop(Session session) {
       Logger.info("session停止:id为 {}", session.getId());
       removeInvalidUser(session);
   }

   @Override
   public void onExpiration(Session session) {
       Logger.debug("session过期:id为 {}", session.getId());
       saveExpireLog(session); ###记录用户会话过期日志逻辑
       removeInvalidUser(session);
   }

   @SuppressWarnings("unchecked")
   private void removeInvalidUser(Session session) { }
   }
