在 JerseyTest 中找不到媒体类型 =multipart/form-data 的 MessageBodyWriter
MessageBodyWriter not found for media type=multipart/form-data in JerseyTest
我正在尝试为 Jersey 程序中资源 class 中的 POST 方法创建测试。
这是资源的 POST 方法：
@POST @Path("/new")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response HTTPPostMethod(@FormDataParam("file") InputStream fileIS,
@FormDataParam("file") FormDataContentDisposition contentDispositionHeader) {
// ... some code that handles the InputStream
}
我的 ResourceConfig 是通过以下方式创建的：
public class MyApp extends ResourceConfig {
public MyApp(String param) {
register(createMoxyJsonResolver());
register(MultiPartFeature.class);
register(MyResource.class);
}
private static ContextResolver<MoxyJsonConfig> createMoxyJsonResolver() {
final MoxyJsonConfig moxyJsonConfig = new MoxyJsonConfig();
Map<String, String> nsPrefixManager = new HashMap<String, String>(1);
nsPrefixManager.put("http://www.w3.org/2001/XMLSchema-instance", "xsi");
moxyJsonConfig.setNamespacePrefixMapper(nsPrefixManager).setNamespaceSeparator(':');
return moxyJsonConfig.resolver();
}
/**
* Start the Grizzly HTTP Server
*
*/
public final void startHttpServer(int port) {
try {
final String url = "http://localhost:" + port + "/myapp";
final HttpServer server =
GrizzlyHttpServerFactory
.createHttpServer(URI.create(url), this);
Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {
public void run() {
server.shutdown();
}
}));
Thread.currentThread().join();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
try {
final MyApp app = new MyApp(args[1]);
int port = Integer.parseInt(args[0]);
app.startHttpServer(port);
} catch(NumberFormatException e) {
e.printStackTrace();
}
}
}
我的球衣测试设置：
public class TestBase extends JerseyTest {
protected Application app;
protected static final String param = "myparam";
@Override
protected Application configure() {
// The MultiPartFeature is registered.
this.app = new MyApp(param);
return app;
}
}
最后，导致问题的测试：
public class MyResourceTest extends TestBase {
// ...
@Test
public void testHTTPPost() {
try {
FileDataBodyPart filePart = new FileDataBodyPart("file", new File("path/to/a/file/i/know/exists"));
FormDataMultiPart formDataMultipart = new FormDataMultiPart();
FormDataMultiPart multipart = (FormDataMultiPart)formDataMultipart.bodyPart(filePart);
Response result = target("/myResource/new").request().post(Entity.entity(multipart, multipart.getMediaType()));
formDataMultipart.close();
multipart.close();
assertEquals(Response.Status.OK.getStatusCode(), result.getStatus());
} catch (IOException e) {
e.printStackTrace();
}
}
// ...
}
我总是收到错误消息：

我在 TestBase 中尝试了以下代码，但没有成功：
@Override
protected Application configure() {
ResourceConfig app = new ResourceConfig();
app.register(MultiPartFeature.class);
app.register(MyResource.class);
this.app = app;
return app;
}
同样的错误。我在这里做错了什么？
MultiPartFeature 注册所需的 MessageBodyWriter/MessageBodyReader 来处理多部分。您已经在服务器上注册了它（它将使用 reader 来反序列化入站请求实体），但是您还需要在客户端上注册它（它使用编写器来序列化出站请求实体）。
实际上有几个地方可以注册。一对是同WebTarget还是同Client。如果你想用客户端注册它，你可以覆盖 JerseyTest
中的 configureClient(ClientConfig)
@Override
public void configureClient(ClientConfig config) {
config.register(MultiPartFeature.class);
}
或者，使用 WebTarget，您可以简单地执行
target(...).register(MultiPartFeature.class)..
我正在尝试为 Jersey 程序中资源 class 中的 POST 方法创建测试。
这是资源的 POST 方法：
@POST @Path("/new")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response HTTPPostMethod(@FormDataParam("file") InputStream fileIS,
@FormDataParam("file") FormDataContentDisposition contentDispositionHeader) {
// ... some code that handles the InputStream
}
我的 ResourceConfig 是通过以下方式创建的：
public class MyApp extends ResourceConfig {
public MyApp(String param) {
register(createMoxyJsonResolver());
register(MultiPartFeature.class);
register(MyResource.class);
}
private static ContextResolver<MoxyJsonConfig> createMoxyJsonResolver() {
final MoxyJsonConfig moxyJsonConfig = new MoxyJsonConfig();
Map<String, String> nsPrefixManager = new HashMap<String, String>(1);
nsPrefixManager.put("http://www.w3.org/2001/XMLSchema-instance", "xsi");
moxyJsonConfig.setNamespacePrefixMapper(nsPrefixManager).setNamespaceSeparator(':');
return moxyJsonConfig.resolver();
}
