spring boot 配置拦截器

话不多说上代码

package com.admin.demo.controller; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpSession; import org.springframework.web.servlet.HandlerInterceptor; import org.springframework.web.servlet.ModelAndView; public class Interceptor1 implements HandlerInterceptor { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response,Object handler) throws Exception{ HttpSession session=request.getSession(); Object ob=session.getAttribute("name"); if (ob!=null) { return true; } session.setAttribute("preurl",request.getRequestURI()); StringBuffer url = request.getRequestURL(); String tempContextUrl = url.delete(url.length() - request.getRequestURI().length(), url.length()).append(request.getServletContext().getContextPath()).append("/").toString(); response.sendRedirect("/user/login"); //response.sendRedirect(tempContextUrl); return false; } @Override public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,ModelAndView model) throws Exception{ } @Override public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler,Exception ex) throws Exception{ } } // 要调用WebMvcConfigurer接口 @Override public void addInterceptors(InterceptorRegistry registry){ InterceptorRegistration ir=registry.addInterceptor(new Interceptor1()); ir.addPathPatterns("/**"); // ir.excludePathPatterns("/stu/save","/stu/getClassGid","/stu/pageList","/stu/getClassAll","/index/index","/index/right","/stu/news","/stu/pageList","/stu/indexData","/stu/getEditData","/stu/getClass","/stu/del","/stu/edit","/stu/login","/stu/index","/stu/add","/js/**","/html/**","/images/**","/css/**"); ir.excludePathPatterns("/user/login","/user/dologin","/user/yzm","/js/**","/html/**","/images/**","/css/**"); // 需要放行的路径 }
