新建包com.example.interceptor;
创建login拦截类
package com.example.interceptor;import org.springframework.web.servlet.HandlerInterceptor;import org.springframework.web.servlet.ModelAndView;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import javax.servlet.http.HttpSession;public class LoginInterceptor implements HandlerInterceptor { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { //请求进入这个拦截器 HttpSession session = request.getSession(); if(session.getAttribute("user") == null){ //判断session中有没有user信息// System.out.println("进入拦截器"); if("XMLHttpRequest".equalsIgnoreCase(request.getHeader("X-Requested-With"))){ response.sendError(401); } response.sendRedirect("/"); //没有user信息的话进行路由重定向 return false; } return true; //有的话就继续操作 } @Override public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception { } @Override public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception { } }
在com.example包中添加拦截控制器
package com.example;import com.example.interceptor.LoginInterceptor;import com.example.interceptor.RightsInterceptor;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.*;@Configuration //使用注解 实现拦截public class WebAppConfigurer implements WebMvcConfigurer { @Autowired RightsInterceptor rightsInterceptor; @Override public void addInterceptors(InterceptorRegistry registry) { //登录拦截的管理器 InterceptorRegistration registration = registry.addInterceptor(new LoginInterceptor()); //拦截的对象会进入这个类中进行判断 registration.addPathPatterns("/**"); //所有路径都被拦截 registration.excludePathPatterns("/","/login","/error","/static/**","/logout"); //添加不拦截路径 } }
在WebAppConfigurer.java中增加内容
package com.example;import com.example.interceptor.LoginInterceptor;import com.example.interceptor.RightsInterceptor;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.*;@Configuration //使用注解 实现拦截public class WebAppConfigurer implements WebMvcConfigurer { @Autowired RightsInterceptor rightsInterceptor; @Override public void addInterceptors(InterceptorRegistry registry) { //登录拦截的管理器 InterceptorRegistration registration = registry.addInterceptor(new LoginInterceptor()); //拦截的对象会进入这个类中进行判断 registration.addPathPatterns("/**"); //所有路径都被拦截 registration.excludePathPatterns("/","/login","/error","/static/**","/logout"); //添加不拦截路径// super.addInterceptors(registry); //权限拦截的管理器 InterceptorRegistration registration1 = registry.addInterceptor(rightsInterceptor); registration1.addPathPatterns("/**"); //所有路径都被拦截 registration1.excludePathPatterns("/","/login","/error","/static/**","/logout"); //添加不拦截路径 } }
