如何设置restTemplate参数类型？

Question

这是我的代码

RestTemplate restTemplate = new RestTemplate(); 

    MultiValueMap<String, Object> vars = new LinkedMultiValueMap<String, Object>(); 
    vars.add("name", fileName); 
    vars.add("parent", "43"); 
    vars.add("size_s3", size_s3); 
    vars.add("size_ssg", size_ssg); 
    vars.add("size", size); 

    HttpHeaders headers = new HttpHeaders(); 
    headers.set("Authorization","token "+user.getToken()); 
    headers.setContentType(MediaType.APPLICATION_JSON); 

    HttpEntity<?> entity = new HttpEntity<MultiValueMap<String, Object>>(vars, headers); 
    result = restTemplate.exchange(RestInfo.restURL+"/files", HttpMethod.POST, entity, String.class).getBody(); 

的httpClientErrorException是400 BAD REQUEST

{ “size_s3”：[ “输入一个整数。”]， “父”：[“不正确的类型预期pK值，收到名单。“]，”大小“：[”输入一个整数。“]}

我认为prameter类型的问题。所以我试图改变我的代码，像这样

vars.add（“size_s3”，Integer.parseInt（size_s3））;

，但结果是一样的...

RestTemplate restTemplate = new RestTemplate(); 

MultiValueMap<String, Object> vars = new LinkedMultiValueMap<String, Object>(); 
vars.add("name", fileName); 
vars.add("parent", 43); 
vars.add("size_s3", size_s3); 
vars.add("size_ssg", size_ssg); 
vars.add("size", size); 

HttpHeaders headers = new HttpHeaders(); 
headers.set("Authorization","token "+user.getToken()); 
headers.setContentType(MediaType.APPLICATION_JSON); 

HttpEntity<?> entity = new HttpEntity<Object>(vars, headers); 
result = restTemplate.exchange(RestInfo.restURL+"/files", HttpMethod.POST, entity, String.class).getBody(); 

我会在你的代码的一些变化试试
