    新建一个包Interceptor

    新建一个过滤器

    package net.Interceptor;
    
    import java.io.PrintWriter;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    
    import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
    
    public class AuthInterceptor extends HandlerInterceptorAdapter {
    	public boolean preHandle(HttpServletRequest request,
    		 	HttpServletResponse response, Object handler) throws Exception {
    		String servlet = request.getServletPath();
    		PrintWriter out = response.getWriter();
    		out.append(servlet);
    		out.close();
    		return true;
    	}
    }
