Java org.springframework.web.client.HttpClientErrorException:RestTemplate中存在400个错误请求

我使用Rest模板发布数据json，当我测试o Postmen时，它运行success并返回200

这是我的json格式：

{
"senderUser": "user@gmail.com",
"data": [
{
  "actionType": "update-contact",
  "data": {
  "name": "luong van",
  "lastname": "khanh",
  "type": 0,
  "title": "",
  "passport": "",
  "gender": 1,
  "bgInfo": "",
  "dateOfBirth": "",
  "emails": [{"value": "user@gmail.com"}],
  "phones": [{"value": "0902032618"}],
  "addresses": [{"street": "10", "city":"Osaka", "state": "Osake", "country":       
    {"code":"JP", "name":"Japan"}}],
  "tag": ""
 }
 }
]
}

这是我的消息来源：

public static void main(String []args) {

    RestTemplate restTemplate = new RestTemplate();
    
    MappingJackson2HttpMessageConverter jsonHttpMessageConverter = new MappingJackson2HttpMessageConverter();
    jsonHttpMessageConverter.getObjectMapper().configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
    
    restTemplate.getMessageConverters().add(jsonHttpMessageConverter);

    String url = "https://myservice.com/listeners/60011cbd4a674458d3b26025/90336429462601e7f3326641898fabd9948b349d";

    try {
        System.out.println("hi there");

        JSONArray json = new JSONArray();
        JSONObject obj = new JSONObject();

        obj.put("name", "khanh");
        obj.put("lastname", "luong van");
        obj.put("type", "0");
        obj.put("dateOfBirth", "");
        obj.put("emails", "user@gmail.com");
        obj.put("phones", "0902032618");
        obj.put("addresses", "Osaka");

        json.put(obj);
        HttpHeaders headers = new HttpHeaders();
        headers.add("Accept", MediaType.APPLICATION_JSON.toString());
        headers.add("Content-Type", MediaType.APPLICATION_JSON.toString());

        HttpEntity<String> entity = new HttpEntity<String>(obj.toString(), headers);         
        String result = restTemplate.postForObject(url, entity, String.class);          
        System.out.println(result);
    }
    catch(Exception e) {
        e.printStackTrace();
    }
}

我尝试了很多方法，但仍然发生同样的错误，我如何解决这个问题？非常感谢

在这种情况下，我认为错误的请求是正确的答案。 在使用Postman的测试中，您通过了请求正文：

除非您尝试使用的服务足够通用，可以接受太多不同的请求主体，否则它将触发错误的请求响应

我建议您将邮递员的请求正文作为参数传递给HTTPEntity构造函数作为测试：

使用与JSON模式和Jacksonmapper或类似工具匹配的POJO来节省时间。POJO到JSON，反之亦然，这并不是一个您需要对IMO过多担心的问题，因为有框架级的功能和库可以解决这个问题。使用JSONArray和JSONObject构建它过于冗长，而且容易出现人为错误。

你能给我详细的回答吗？@luongkhanh我两次粘贴同一请求正文时出错了。我已经改正了。我的建议是让一个测试通过与你通过邮递员完全相同的身体。你可以考虑看一下KaTik PV的建议。使用POJO和类似Jackson或Gson的序列化库可以节省您的时间，并且不太容易出错。您能给我详细的答案吗？@luongkhanh我两次粘贴相同的请求正文时出错了。我已经改正了。我的建议是让一个测试通过与你通过邮递员完全相同的身体。你可以考虑看一下KaTik PV的建议。使用POJO和类似Jackson或Gson的序列化库可以节省时间，并且不太容易出错。
