Java自定義異常、全局捕獲異常、攔截器 實現動態控制登錄超時

參考文章：https://blog.csdn.net/psp0001060/article/details/53380160

自定義異常類

package com.jeeplus.common.customException;  2 
/**
 * 登陸超時自定義異常  5  */
public class LoginTimeOutException extends Exception {  7 
    private String message;  9 
    public LoginTimeOutException() { 11  } 12 
    public LoginTimeOutException(String message) { 14         super(message); 15         this.message = message; 16  } 17 
 @Override 19     public String getMessage() { 20         return message; 21  } 22 
    public void setMessage(String message) { 24         this.message = message; 25  } 26 }

 全局捕獲異常

import org.springframework.web.servlet.HandlerExceptionResolver;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * 全局異常處理器
 */
public class OverallExceptionResolver implements HandlerExceptionResolver {
    @Override
    public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object o, Exception e) {
        //handler為當前處理器適配器執行的對象
        String message = null;
        //判斷是否為系統自定義異常。
        if(e instanceof LoginTimeOutException) {
            message = ((LoginTimeOutException) e).getMessage();
            ModelAndView modelAndView = new ModelAndView();
            //跳轉到相應的處理頁面
            modelAndView.setViewName("modules/sys/sysLogin");
            return modelAndView;
        }
        else {
            e.printStackTrace();
            return null;
        }
    }
}

 在springmvc.xml文件中配置

<!--全局異常捕獲-->
    <bean id="exceptionResolver" class="com.jeeplus.common.customException.OverallExceptionResolver"></bean>

 

監聽器

public class TimeOutInterceptor extends BaseService implements HandlerInterceptor {

    @Autowired
    IdentityAuthenticationTimeService identityTimeService;
    
    /**
     * 判斷是否登陸超時
     * @param request
     * @param response
     * @param o
     * @return
     * @throws Exception
     */
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object o) throws Exception {
        Principal principal = UserUtils.getPrincipal();
        if (principal != null){
            HttpSession sessionStart = request.getSession();
            Long time = (Long) sessionStart.getAttribute("accessTime");

            if (time != null){
                Long timeSection = System.currentTimeMillis() - time;
                Long ts = timeSection/1000/60;
                Integer a = identityTimeService.getIdentityTime();
                logger.info("當前重鑒別時間：" + a + "分鍾");
                logger.info("距離上次操作：" + ts + "分鍾");
                if (ts >= a){
                    logger.info("登錄超過：" + a + "分鍾，返回登錄頁！");
                    UserUtils.getSubject().logout();
                    throw new LoginTimeOutException("登錄超時！");
                }
            }
            sessionStart.setAttribute("accessTime",System.currentTimeMillis());
        }
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {

    }

    @Override
    public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {

    }
}

在springmvc.xml文件中配置監聽器
