com.sun.jersey.api.client.ClientHandlerException

我在我的REST應用程序中使用了Jersey。我需要用junit來測試它。但我得到了一個com.sun.jersey.api.client.ClientHandlerException。 Stacktrace：com.sun.jersey.api.client.ClientHandlerException

我不知道如何解決這個錯誤。我期待着您的幫助。我的代碼：

@Path("/student") 
@Component 
public class StudentResourse { 
@Autowired 
private StrudentService service; 

@Path("/getStudent/{id}") 
@GET 
@Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON }) 
public Student getStudent(@PathParam("id") long id) { 
    return service.get(id); 
} 
}

此課程正常工作。當我在瀏覽器中鍵入：http://127.0.0.1:8080/Application/student/getStudent/100500它讓我看到學生XML 我的測試類：

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = "classpath:configuration.xml") 
@TestExecutionListeners({ DbUnitTestExecutionListener.class, 
    DependencyInjectionTestExecutionListener.class, 
    DirtiesContextTestExecutionListener.class, 
    TransactionalTestExecutionListener.class }) 
public class StudentResourseTest extends JerseyTest { 

@Override 
protected AppDescriptor configure() { 
    return new WebAppDescriptor.Builder("com.example.servlet") 
      .contextPath("context").build(); 
} 

@Override 
protected TestContainerFactory getTestContainerFactory() { 
    return new HTTPContainerFactory(); 
} 

@Test 
@DatabaseSetup("dataset.xml") 
public void test() throws UnsupportedEncodingException { 
     ClientConfig config = new DefaultClientConfig(); 
     Client client = Client.create(config); 
     WebResource service = client.resource(getBaseURI()); 
     ClientResponse response = service.path("getStudent").path("100500") 
       .accept(MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON) 
       .get(ClientResponse.class); 
     Student student = (Student) response.getEntity(Student.class); 
     System.out.println(student); 
} 

@Override 
public URI getBaseURI() { 
    return UriBuilder.fromUri("http://127.0.0.1:8080/Application/student/") 
      .build(); 
}

}

我使用這種依賴關係：

<dependency> 
    <groupId>com.sun.jersey.jersey-test-framework</groupId> 
    <artifactId>jersey-test-framework-http</artifactId> 
    <version>1.2</version> 
</dependency>

Student類標記爲@XmlRootElement 。問題在測試課上。有任何想法嗎？感謝您的解答

你在1.2版本中使用，甚至新澤西后？你需要使用這樣一箇舊版本，或者你可以切換到最新的1.17.1版本嗎？接收到的響應的HTTP狀態是什麼？ –

它返回404 Not Found。我不知道爲什麼，因爲它在瀏覽器中工作 –

您正在將應用程序部署到context上下文路徑，但是您假定（通過重寫getBaseURI()方法）應用程序部署在Application上下文路徑中。嘗試刪除壓倒一切的getBaseURI()方法並更改測試方法如下：

@Test 
@DatabaseSetup("dataset.xml") 
public void test() throws UnsupportedEncodingException { 
    ClientResponse response = resource() 
     .path("students").path("getStudent").path("100500") 
     .accept(MediaType.APPLICATION_XML) 
     .get(ClientResponse.class); 

    Student student = (Student) response.getEntity(Student.class); 
    System.out.println(student); 
}

同時檢查HTTP響應狀態（應該是200）和響應媒體類型（應該是在這種情況下application/xml - 如果你要求application/xml並得到application/octet-stream東西顯然是錯的）。使用

請檢查A message body writer for Java type, class myPackage.B, and MIME media type, application/octet-stream, was not found

& this link解決您的issue.I希望這是足以解決你的問題。
