}
}
]
}
This is my class:这是我的 class:
public class InComingAPI {
private static Logger logger = LoggerFactory.getLogger(InComingAPI.class);
public static void main(String []args) {
RestTemplate restTemplate = new RestTemplate();
String url = "https://myservice/90336429462601e7f3326641898fabd9948b349d";
try {
logger.info("hi there");
// RestTemplate restTemplate = new RestTemplate();
// String url = "http://localhost:8181/xyz/updateAdmin";
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, json, String.class);
System.out.println(result);
}
catch(Exception e) {
e.printStackTrace();
}
}
}
and it happens an exception following as:它发生以下异常:
2021-01-22 17:50:17,280 INFO [com.outincoming.InComingAPI] hi there
org.springframework.web.client.RestClientException: Could not write request: no suitable HttpMessageConverter found for request type [org.json.JSONArray]

How I can fix the problem?我该如何解决这个问题? many thank
多谢
Actually, the exception thrown is totally misleading.实际上,抛出的异常完全是误导性的。 Turned out the problem is not that the MappingJackson2HttpMessageConverter didn't know how to marshall my object -which sounded strange, being JSON-, but a configuration of the underlying ObjectMapper.
原来问题不在于 MappingJackson2HttpMessageConverter 不知道如何编组我的 object——听起来很奇怪,是 JSON——,而是底层 ObjectMapper 的配置。
What I did is to disable the property SerializationFeature.FAIL_ON_EMPTY_BEANS like that我所做的是像那样禁用属性 SerializationFeature.FAIL_ON_EMPTY_BEANS
public class InComingAPI {
private static Logger logger = LoggerFactory.getLogger(InComingAPI.class);
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/90336429462601e7f3326641898fabd9948b349d";
try {
logger.info("hi there");
// RestTemplate restTemplate = new RestTemplate();
// String url = "http://localhost:8181/xyz/updateAdmin";
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, json, String.class);
System.out.println(result);
}
catch(Exception e) {
e.printStackTrace();
}
}
