Question

我在JBoss上运行以下REST服务：

@POST
@Path("/postTest")
@Consumes(MediaType.APPLICATION_JSON)
@Produces({ MediaType.APPLICATION_JSON })
public Response PostTest(MyOwnUserData user)
{
    return Response.ok(user, MediaType.APPLICATION_JSON).build();
}

在另一个程序中，我试图使用以下代码调用此方法：

import org.springframework.http.HttpHeaders;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.web.client.RestTemplate;
import org.springframework.http.HttpEntity;
import java.util.Arrays;

public static void main(String[] args) 
{
    String mainUrl = "http://localhost:8080/services/users/test/posTest";

    ResponseEntity<MyOwnUserData > n2 = null;
    RestTemplate n = new RestTemplate();

    MyOwnUserData u = new MyOwnUserData ();

    HttpHeaders headers = new HttpHeaders();
    // This is needed to set the content-type header as application/json. The web service will throw a 415 Media Type unsupported if you dont set this.
    headers.setContentType(MediaType.APPLICATION_JSON);

    HttpEntity<MyOwnUserData> entity = new HttpEntity(u,headers);

    n2 = n.postForEntity(mainUrl,u, MyOwnUserData .class);

}

当我执行第二个程序时，它总是给出BAD_REQUEST。

错误：

Exception in thread "main" org.springframework.web.client.HttpClientErrorException: 415 Unsupported Media Type

JBOSS执行时记录错误：

Answer 1

尝试替换

ResponseEntity<MyOwnUserData> n2 = null;
n2 = n.postForEntity(mainUrl,u, MyOwnUserData.class);

带

file_content = File.read('path to file with extension');
MyModel.create(text: file_content);

Answer 2

可以使用

 UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl("http://localhost:8080/test/postTest");

 n.postForEntity(builder.build().encode().toUri(), u, MyOwnUserData.class)

Answer 3

你需要做这样的事情：

// Set the message converter so as to enable marshalling/demarshalling for json
restTemplate.setMessageConverters(Arrays.asList(new MappingJackson2HttpMessageConverter()));

HttpHeaders headers = new HttpHeaders();
// This is needed to set the content-type header as application/json. The web service will throw a 415 Media Type unsupported if you dont set this.
headers.setContentType(MediaType.APPLICATION_JSON);

HttpEntity<MyOwnUserData> entity = new HttpEntity<MyOwnUserData>(u,headers);
Response response = restTemplate.postForObject(mainUrl, entity, Response.class);

使用Java代码来使用Restful Web服务
