java - RestTemplate post值无法传递

Question

用restTemplate调用接口(interface)，接口(interface)无法接受数据，代码如下`

    Map<String,Object> map = new HashMap<String,Object>();
    map.put("name", "xiaohong");

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    HttpEntity<Map<String,Object>> httpEntity = new HttpEntity<Map<String,Object>>(map,headers);

    List<HttpMessageConverter<?>> coverterList = new ArrayList<HttpMessageConverter<?>>();
    coverterList.add(new MappingJackson2HttpMessageConverter());
    coverterList.add(new StringHttpMessageConverter());
    coverterList.add(new FormHttpMessageConverter());


    String url = "http://127.0.0.1:8099/test/tput/xiaoming";
    RestTemplate restTemplate = new RestTemplate();
    restTemplate.setMessageConverters(coverterList);
    ResponseEntity<Object> result = restTemplate.postForEntity(url, httpEntity, Object.class);








@ResponseBody
@RequestMapping(value="/tput/{age}", method = RequestMethod.POST)
public Object testput(HttpServletRequest request,@PathVariable("age") String age){

    // name is null
    String name = request.getParameter("name");
    System.out.println(name);


    Map<String,Object> map = new HashMap<String,Object>();
    map.put("name", name);
    map.put("age", age);
    return map;

`无法获取“名称”的值打印结果:null

Answer 1

restTemplate表单提交需要设置默认的HttpHeaders，`

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("name", "yyyyyyy");
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

HttpEntity<MultiValueMap<String, String>> httpEntity = new HttpEntity<MultiValueMap<String,String>>(map,headers);

` 该请求可能会得到

`String name = request.getParameter("name");`
