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();
}
}生成日志时出现异常：

我认为在这种情况下，错误的要求是正确的答案。在使用postman的测试中，您通过了请求主体：
当您的应用程序日志显示您正在发送请求正文时：
除非您尝试使用的服务具有足够的通用性，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postman的请求主体作为参数传递给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，这并不是一个你需要对imo过于担心的问题，因为有框架级的功能和库来解决这个问题。用jsonarray和jsonobject构建它过于冗长，而且容易出现人为错误。
