测试的main方法

测试的main方法
    public static void main(String[] args) {
        RestTemplate restTemplate = new RestTemplate();
        // 用HTTP GET方法去请求，并且返回一个对象
//        ResponseEntity<String> response = restTemplate.getForEntity(
//                "http://localhost:8080/users/1", String.class);
//        System.out.println(response.getBody());

        String forObject = restTemplate.getForObject(
                "http://localhost:8080/users/1",
                String.class
        );
        System.out.println(forObject);
    }

百思不得其解，还请老师看看
