可以在请求中传递自定义对象，并在post中以“*/*”(Mediatype.all_value)的形式接收响应

Question

我试图使用RESTTEMPLATE触发restApi.request接受json（我已经为它创建了一个自定义对象）并以“/”mediatype的形式发送响应。

预期请求：

{
"domainObject" :{
    "amount" : "1230798F",
    "business" : "n/a",
    "productGroup" : "n/a",
    "productType" : "n/a",
    "balanceType" : "n/a", 
    "balanceSubType" : "n/a"       
},
   "uniqueId" : "test1",
    "userId" : "user1"
}

@Entity
@AllArgsConstructor
class DomainObject(){
   private Float amount;
   private String business;
   private String productGroup;
   private String productType;
   private String balanceType;
   private String balanceSubType;

}

@Entity
@AllArgsConstructor
class PayloadObject(){

   @Autowired
   private DomainObject domainObject;

   private String uniqueId;
   private String userId;
}

public void testRestTemplate(){
PayloadObject obj = new PayloadObject(domainObject, "test-1", "abc");
RestTemplate restTemplate = new RestTemplate();
String url = "https://dev-test";

}

//make the object
NewObject obj = new NewObject();
obj.setStuff("stuff");

//set your headers
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);

//set your entity to send
HttpEntity entity = new HttpEntity(obj,headers);

// send it!
ResponseEntity<String> out = restTemplate.exchange("url", HttpMethod.POST, entity
    , String.class);`

Edit2:我尝试添加messageConverter，如下所示：

List<HttpMessageConverter<?>> msgConverter = new ArrayList<HttpMessageConverter<?>>
MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
converter.setSupportMediaType(Collections.singletonList(MediaType.ALL));
msgConverter.add(converter);
restTemplate.setMessageConverters(msgConverter);

但它仍然给出了同样的错误。我想知道我是否需要编写自定义消息转换器？有人能帮我明白我是否走在正确的道路上吗？

retune类型应该是PayloadObject而不是String类型。

ResponseEntity<PayloadObject> out = restTemplate.exchange("url", HttpMethod.POST, entity
, PayloadObject.class);
