    import java.util.Enumeration;
    
    @RestController

    {
        @RequestMapping(value = "/test1")
        public void test1(HttpServletRequest request)
        {
            System.out.println(request.getMethod());   //获取请求方式；
    
            System.out.println(request.getContextPath());  //获取虚拟目录
    
            System.out.println(request.getServletPath());  //获取servlet路径
    
            System.out.println(request.getQueryString());   //获取请求参数
    
            System.out.println(request.getRequestURI());   //获取请求URI，部分
    
            System.out.println(request.getRequestURL());   //获取请求URI，全部
    
    
    
        }
    }
