Question

我正在使用RESTEasy和WildFly 9.0.2开发一组REST服务。

其中一个允许我上传文件。

@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response upload(MultipartFormDataInput input);

我成功设法调用REST服务并将文件上传到服务器，因此我开始实施集成测试。

为此，我使用了嵌入式Grizzly HTTP服务器：

@Before
public void setUp() throws Exception {
    // Weld and container initialization
    weld = new Weld();
    weld.initialize();
    ResourceConfig resourceConfig = new ResourceConfig().packages("...");
    server = GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI), resourceConfig);
}

当我尝试测试新创建的服务时出现了问题：

@Test
public void hubbleMapServiceUploadMapTest() throws FileNotFoundException, IOException {
    Client client = null;
    WebTarget webTarget = null;
    Builder builder = null;
    Response response = null;

    try {
        client = ClientBuilder.newBuilder().build();

        webTarget = client.target(BASE_URI).path("/service/upload");
        builder = webTarget.request(MediaType.APPLICATION_JSON, MediaType.TEXT_PLAIN, MediaType.WILDCARD);

        response = builder.post(Entity.entity(getEntityAsMultipart(), MediaType.MULTIPART_FORM_DATA));

    } catch (Exception ex) {
        ex.printStackTrace();
    } finally {
        if (response != null) {
            response.close();
        }

        if (client != null) {
            client.close();
        }
    }

    assertNotNull(response);
    assertThat(response.getStatus(), is(Status.OK.getStatusCode()));
}

private GenericEntity<MultipartFormDataOutput> getEntityAsMultipart() {
    String resource = "my.file";
    MultipartFormDataOutput mfdo = new MultipartFormDataOutput();

    try {
        mfdo.addFormData("file",
                new FileInputStream(new File(getClass().getClassLoader().getResource(resource).getFile())),
                MediaType.APPLICATION_OCTET_STREAM_TYPE, resource);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }

    GenericEntity<MultipartFormDataOutput> entity = new GenericEntity<MultipartFormDataOutput>(mfdo) {
    };

    return entity;
}

响应代码始终为 415 Unsupported Media Type 。

所有剩余的集成测试都能正常运行。

我做错了什么？我是否需要以某种方式启用Grizzly的 Multipart 功能？

按照@peeskillet的建议，我切换到Sun JDK HTTP Server嵌入式服务器，并提供CDI认知。

要实现这一目标，需要执行以下操作：

添加RESTEasy和WELD必需的Maven依赖项：

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jdk-http</artifactId>
    <version>3.0.17.Final</version>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-cdi</artifactId>
    <version>3.0.17.Final</version>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>org.jboss.weld.se</groupId>
    <artifactId>weld-se</artifactId>
    <version>2.3.4.Final</version>
    <scope>test</scope>
</dependency>

配置要在Sun JDK HTTP Server的部署配置中使用的WELD和RESTEasy CDI扩展：

private Weld weld;
private SunHttpJaxrsServer server;

@Before
public void setUp() throws Exception {
    // Weld initialization
    weld = new Weld();
    weld.initialize();

    // RESTEasy CDI extension configuration
    ResteasyCdiExtension cdiExtension = CDI.current().select(ResteasyCdiExtension.class).get();
    ResteasyDeployment deployment = new ResteasyDeployment();
    deployment.setActualResourceClasses(cdiExtension.getResources());
    deployment.setInjectorFactoryClass(CdiInjectorFactory.class.getName());
    deployment.getActualProviderClasses().addAll(cdiExtension.getProviders());

    // Container initialization
    server = new SunHttpJaxrsServer();
    server.setDeployment(deployment);
    server.setPort(8787);
    server.setRootResourcePath("/some-context-root/rest");
    server.getDeployment().getActualResourceClasses().add(MyService.class);
    server.start();
}

为了了解如何配置RESTEasy的CDI扩展程序，我依赖于@John Ament的NettyTest示例。
