    //一个方法处理一个请求，不能一个请求对应两个方法
    @RequestMapping("/handle01")
    public String handle01() {
        System.out.println("RequestMappingTestController............handle01被调用");
        return "success";

    }


   @RequestMapping(value = "/handle02", method = RequestMethod.POST)
    public String handle02() {
        System.out.println("RequestMappingTestController............handle01被调用");
        return "success";
    }

    @RequestMapping(value = "/handle03", params={"username!=123","pwd","!age"})
    public String handle03() {
        System.out.println("RequestMappingTestController............handle01被调用");
        return "success";
    }
