java - 使用 Jersey2.0 访问 JerseyTest 中的 springbean

Question

我有 Spring 的 Jersey 项目。现在我的测试是从 JerseyTest 派生的。当我尝试做时

@AutoWired 
RestTemplate restTemplate;

看起来 Spring 在 Jersey 测试中不起作用。我做了一些研究，发现了一些链接，例如 spring_jersey但它不起作用，因为我使用的是 jersey2.0。

我的代码看起来像

 //AbstractTest 
    package com.test;


            import javax.ws.rs.client.WebTarget;
            import javax.ws.rs.core.Application;

        import org.glassfish.jersey.client.ClientConfig;
        import org.glassfish.jersey.filter.LoggingFilter;
        import org.glassfish.jersey.jackson.JacksonFeature;
        import org.glassfish.jersey.server.ResourceConfig;
        import org.glassfish.jersey.test.JerseyTest;
        import org.glassfish.jersey.server.ServerProperties;
        import org.glassfish.jersey.server.validation.ValidationFeature;

        public abstract class AbstractTest extends JerseyTest
        {
            protected WebTarget getRootTarget(final String rootResource)
            {
                return client().target(getBaseUri()).path(rootResource);
            }

            @Override
            protected final Application configure()
            {
                final ResourceConfig application = configureApplication();

                // needed for json serialization
                application.register(JacksonFeature.class);

                // bean validation
                application.register(ValidationFeature.class);

                // configure spring context
                application.property("contextConfigLocation", "classpath:/META-INF/applicationContext.xml");

                // disable bean validation for tests
                application.property(ServerProperties.BV_FEATURE_DISABLE, "true");

                return application;
            }

            protected abstract ResourceConfig configureApplication();

            @Override
            protected void configureClient(final ClientConfig config)
            {
                // needed for json serialization
                config.register(JacksonFeature.class);

                config.register(new LoggingFilter(java.util.logging.Logger.getLogger(AbstractResourceTest.class.getName()), false));

                super.configureClient(config);
            }
        }



    package com.test;

    import static org.springframework.test.web.client.match.MockRestRequestMatchers.content;
    import static org.springframework.test.web.client.match.MockRestRequestMatchers.method;
    import static org.springframework.test.web.client.response.MockRestResponseCreators.withSuccess;

    //MyTest
        import java.io.FileNotFoundException;
        import java.io.FileReader;
        import java.io.IOException;

    import javax.ws.rs.client.WebTarget;

    import org.springframework.test.web.client.MockRestServiceServer;
    import org.springframework.test.web.client.match.MockRestRequestMatchers;
    import org.springframework.web.client.RestTemplate;

    import junit.framework.Assert;

    public final class MyTest extends AbstractTest
        {

        private static final String ROOT_RESOURCE_PATH = "/testUrl";

        @AutoWired
private RestTemplate restTemplate;
        private MockRestServiceServer mockServer;


        @Before
        public void setup(){
            this.restTemplate = new RestTemplate();
            this.mockServer = MockRestServiceServer.createServer(restTemplate);
        }

        @Test
        public void testPostWithString() {

            WebTarget target = getRootTarget(ROOT_RESOURCE_PATH).path("");
            String entityBody = new String();
            entityBody = " My test data";


            final javax.ws.rs.client.Entity<String> entity = javax.ws.rs.client.Entity.entity(entityBody, "text/plain");


            mockServer.expect(MockRestRequestMatchers.requestTo(ROOT_RESOURCE_PATH)).andExpect(method(HttpMethod.POST)).andExpect(content().string(entityBody))
                    .andRespond(withSuccess("resultSuccess", MediaType.TEXT_PLAIN));


            final Response response = target.request().post(entity);
            Assert.assertNotNull("Response must not be null", response.getEntity());
            Assert.assertEquals("Response does not have expected response code", 200, response.getStatus());

            System.out.println("Response = " + response.getEntity());

            String data = response.readEntity(String.class);

            System.out.println("Response = " + data);
            if(response.ok() != null)
            {
                System.out.println("Ok");
            }
        }
    }

更新:

public class SimpleJerseyTest extends ApplicationContextAwareJerseyTest {
    private static final String ROOT_RESOURCE_PATH = "/test";

    @Override
    public void configureApplication(ResourceConfig config) {
        config.register(MyApp.class);
        config.register(new LoggingFilter(Logger.getAnonymousLogger(), true));
    }

    @Before
    public void setUp() {
        try{
            ((ConfigurableApplicationContext)this.applicationContext).refresh();
            super.setUp();
        }catch(Exception e){

        }
    this.mockServer = MockRestServiceServer.createServer(restTemplate);
    }

    @Autowired
    private RestTemplate restTemplate;

    private MockRestServiceServer mockServer;

    @Test
    public void doitOnce() {
        WebTarget target = target(ROOT_RESOURCE_PATH);

        String entityBody = new String();

        final javax.ws.rs.client.Entity<String> entity = javax.ws.rs.client.Entity.entity(entityBody, "text/plain");


        mockServer.expect(MockRestRequestMatchers.requestTo(ROOT_RESOURCE_PATH)).andExpect(method(HttpMethod.POST)).andExpect(content().string(entityBody))
                .andRespond(withSuccess("resultSuccess", MediaType.TEXT_PLAIN));


        final Response response = target.request().post(entity);


        System.out.println("Response = " + response.getEntity());

        String data = response.readEntity(String.class);

        System.out.println("Response = " + data);
        if(response.ok() != null)
        {
            System.out.println("Ok");
        }
    }
}

我已经添加了bean

src/test/resources/META-INF/applicationContext.xml

<!-- Our REST Web Service client -->
<bean id="restTemplate" class="org.springframework.web.client.RestTemplate"/>

我添加了相同的bean

src/main/resources/META-INF/applicationContext.xml

!-- Our REST Web Service client -->
<bean id="restTemplate" class="org.springframework.web.client.RestTemplate"/>

Answer 1

而不是像这样配置Spring

application.property("contextConfigLocation", "classpath:/META-INF/applicationContext.xml");

您可以使用

application.property("contextConfig", <ApplicationContext>);

这样您就可以拥有 ApplicationContext 的实例，您可以在其中获取 AutowireCapableBeanFactory 。这样，您只需调用 acbf.autowireBean(this) 即可注入(inject)测试类。

这就是我的意思。我测试了它，它适用于简单的情况。但是，如果您尝试注入(inject)的 Bean 不是单例，则效果不会很好，因为将为测试以及您尝试在应用程序代码中注入(inject)的其他位置创建新的单例。

public abstract class ApplicationContextAwareJerseyTest extends JerseyTest {

    protected ApplicationContext applicationContext;

    @Override
    protected final ResourceConfig configure() {
        final ResourceConfig config = new ResourceConfig();
        configureApplication(config);

        this.applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
        config.property("contextConfig", this.applicationContext);
        final AutowireCapableBeanFactory bf = this.applicationContext.getAutowireCapableBeanFactory();
        bf.autowireBean(this);
        return config;
    }

    public final ApplicationContext getApplicationContext() {
        return this.applicationContext;
    }

    protected void configureApplication(ResourceConfig resourceConfig) {};
}

我不确定的一件事是重置将如何进行。我尝试添加

@Before
public void setUp() throws Exception {
    ((ConfigurableApplicationContext)this.applicationContext).refresh();
    super.setUp();
}

进入抽象类，但这似乎没有按预期工作。我使用的测试如下

public class SimpleJerseyTest extends ApplicationContextAwareJerseyTest {


    @Path("test")
    public static class SimpleResource {
        @Autowired
        private MessageService service;

        @GET
        public String getMessage() {
            return this.service.getMessage();
        }
    }

    @Override
    public void configureApplication(ResourceConfig config) {
        config.register(SimpleResource.class);
        config.register(new LoggingFilter(Logger.getAnonymousLogger(), true));
    }

    @Before
    public void before() {
        assertEquals("Hello World", messageService.getMessage());
    }

    @Autowired
    private MessageService messageService;

    @Test
    public void doitOnce() {
        messageService.setMessage("BOOYAH");
        final Response response = target("test").request().get();
        assertEquals("BOOYAH", response.readEntity(String.class));
    }

    @Test
    public void doitTwice() {
        messageService.setMessage("BOOYAH");
        final Response response = target("test").request().get();
        assertEquals("BOOYAH", response.readEntity(String.class));
    }
}

第二个测试得到的结果是，服务消息的值是默认消息“Hello World”，即使我将消息设置为“BOOYAH”。这告诉我应用程序中存在陈旧的服务，该服务与注入(inject)测试中的服务不同。不过，第一个测试效果很好。如果不重置，第二个测试也可以正常工作，但是每个测试中都会留下修改后的服务，这使得测试不是独立的。
