I do not know how to fix this bug. I'm looking forward to your help. My code:
我不知道如何修复这个错误。我期待着你的帮助。我的代码：
@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();
}
This class works fine. When I type in browser: http://127.0.0.1:8080/Application/student/getStudent/100500it shows me student in xml
My test class:
这个类工作正常。当我在浏览器中输入时：http://127.0.0.1:8080/Application/student/getStudent/100500它以 xml 格式显示我的学生我的测试类：
<dependency>
<groupId>com.sun.jersey.jersey-test-framework</groupId>
<artifactId>jersey-test-framework-http</artifactId>
<version>1.2</version>
</dependency>
}
}
I'm using this dependency:
我正在使用此依赖项：
@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);
}
Student class marked as @XmlRootElement. Problem is in test class. Any ideas? Thanks for you answers
学生类标记为@XmlRootElement。问题出在测试课上。有任何想法吗？谢谢你的回答

You're deploying your application to contextcontext-path but then you're assuming (by overriding getBaseURI()method) that the application is deployed on Applicationcontext-path. Try to remove the overriding getBaseURI()method and change the test method to following:
您将应用程序部署到context上下文路径，但随后您假设（通过覆盖getBaseURI()方法）应用程序部署在Application上下文路径上。尝试删除覆盖getBaseURI()方法并将测试方法更改为以下内容：
Also check for HTTP response status (should be 200) and response media-type (should be application/xmlin this case - if you request application/xmland get application/octet-streamsomething is clearly wrong).
还要检查 HTTP 响应状态（应该是200）和响应媒体类型（application/xml在这种情况下应该是- 如果您请求application/xml并得到application/octet-stream某些东西显然是错误的）。

using below annortation @XmlRootElement and change library of jersey AND server log clean after publish the project
发布项目后使用以下注释@XmlRootElement 并更改球衣库和服务器日志清理
