java Jersey JUnit测试框架错误状态500

Question

我想用jersey test framework测试我的jersey 1-应用程序

我想测试一下：

@Path("fieldgen")
public class VRApi {

@Path("/testCon")
@GET
@Produces(MediaType.APPLICATION_JSON)
public String testCon() {

    return "testcon";
}

@Path("/getTestObj")
@GET
@Produces(MediaType.APPLICATION_JSON)
public TestObj getField() {

    TestObj tobj= new TestObj ("str1", "str2", "str3");
    return tobj;
}

这是我的测试课：

public class TestMB extends JerseyTest{

private WebResource webResource = resource();

public TestMB() throws Exception {
    super("...api...");
}

@Test
public void testCon() {

    String responseMsg = webResource.path("/fieldgen/testCon").get(String.class);
    assertEquals("testcon", responseMsg);       
}


@Test
public void getTestObj()  {

    WebResource.Builder mbRes = webResource.path("/fieldgen/getTestObj").accept(MediaType.APPLICATION_JSON);
    TestObj vr = mbRes.get(TestObj.class);

    assertEquals(vr, new TestObj("str1", "str2", "str3"));
}   

第一次测试没问题。 第二次测试失败：

  A message body writer for Java class modelVR.TestObj, and Java type class 
  modelVR.TestObj, and MIME media type application/json was not found

我也试着使用ClientResponse。 警察局副局长：

有什么问题吗？谢谢

检查是否已按照jersey docs here中的说明在客户端注册Pojo映射功能。下面给出了相关片段

 ClientConfig clientConfig = new DefaultClientConfig();
 clientConfig.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);
 Client client = Client.create(clientConfig)
