相比springmvc，springboot中攔截器不需要在xml中配置，只需定義攔截器類?implements HandlerInterceptor

和攔截器攔截路徑的配置類extends WebMvcConfigurerAdapter

1.SessionInterceptor

package com.example.demo;import org.springframework.web.servlet.HandlerInterceptor; import org.springframework.web.servlet.ModelAndView;import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;/*** Created by 20160216 on 2018/2/8.*/ public class SessionInterceptor implements HandlerInterceptor {@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object o) throws Exception {System.out.println("uri="+request.getRequestURI());//登錄不做攔截if(request.getRequestURI().equals("/userbg/login") || request.getRequestURI().equals("/user/login_view")){return true;}//驗證session是否存在Object obj = request.getSession().getAttribute("_session_user");if(obj == null){response.sendRedirect("/user/login_view");return false;}return true;}@Overridepublic void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {}@Overridepublic void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {} }

2.SessionConfiguration

package com.example.demo;import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.InterceptorRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;/*** Created by 20160216 on 2018/2/8.*/ @Configuration public class SessionConfiguration extends WebMvcConfigurerAdapter {@Overridepublic void addInterceptors(InterceptorRegistry registry) {registry.addInterceptor(new SessionInterceptor()).addPathPatterns("/**");} }
