RestTemplate调用接口总结

1.

这是接口信息

    @PostMapping("/testm")
    public ReturnResult show11(@RequestParam("id") String id,
                               @RequestParam("name") String name) {
        System.out.println(id);
        UserInfo userInfo = userInfoMapper.selectByUserName(name);

        return ReturnResult.create(userInfo);
    }

这是restTemplate调用 

    //Post,@RequestParam---postForEntity
    @Test
    public void sho11() {
        String url = "http://127.0.0.1:8099/user/testm";
        MultiValueMap<String, String> request = new LinkedMultiValueMap<>();
        request.add("id", "12324");
        request.add("name", "nanc");

        ResponseEntity<ReturnResult> resp = restTemplate.postForEntity(url, request, ReturnResult.class);
        ReturnResult body = resp.getBody();
        UserInfo data = body.getData();
        System.err.println(data.getUserId());
        System.out.println(data);


    }

2.

接口

    @GetMapping("/testp")
    public ReturnResult show22(@RequestParam String name,
                               @RequestParam Integer age,
                               @RequestParam String clazz) {
        System.out.println(name + "-" + age + "-" + clazz);
        UserInfo userInfo = userInfoMapper.selectByUserName(name);
        return ReturnResult.create(userInfo);
    }

 resttemplate

    //Get ,@RequestParam-----getForObject
    @Test
    public void sho12() {
        String url = "http://127.0.0.1:8099/rest/testp?name={name}&age={age}&clazz={clazz}";
        Map<String, Object> map = new HashMap<>();
        map.put("name", "nanc");
        map.put("age", 34);
        map.put("clazz", "12");
        ReturnResult forObject = restTemplate.getForObject(url, ReturnResult.class, map);
        UserInfo data = forObject.getData();
        System.out.println(data);
    }
