spring设置拦截器代码实例
人气:0拦截器(拦截都是控制层的地址。 filter: )
创建一个类 实现接口 HandlerInterceptor
package com.zhiyou100.wyf.interceptor; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.HandlerInterceptor; import org.springframework.web.servlet.ModelAndView; public class MyInterceptor implements HandlerInterceptor{ @Override public void afterCompletion(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, Exception arg3) throws Exception { System.out.println("结束"); } @Override public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, ModelAndView arg3) throws Exception { System.out.println("预备"); } @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object arg2) throws Exception { Object name = request.getSession().getAttribute("name"); if(name!=null) { return true; }else { response.sendRedirect("../denglu.jsp"); return false; } } }
重写接口的中方法
把创建的类配置到springmvc文件中。
<!-- 配置拦截器 --> <mvc:interceptors> <mvc:interceptor> <mvc:mapping path="/user/**"/> <mvc:exclude-mapping path="/user/login"/> <mvc:exclude-mapping path="/user/register"/> <mvc:exclude-mapping path="/user/stu1"/> <bean class="com.zhiyou100.wyf.interceptor.MyInterceptor"></bean> </mvc:interceptor> </mvc:interceptors>
