简单的学科竞赛管理系统
前端用的thymeleaf，
后端是ssm+springboot
登录拦截器
package com.competition.interceptor;
import org.springframework.web.servlet.HandlerInterceptor;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
- @Des 定义登录拦截器
*/
public class LoginHandlerInterceptor implements HandlerInterceptor {
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
Object usr = request.getSession().getAttribute("loginUser");
if (usr!=null){
return true;
}
//没有登录
request.setAttribute("msg","请先登录");
//转发到 拦截器的index.html
request.getRequestDispatcher("/index.html").forward(request,response);
return false;
}
}
