泽西2注射源为multipart formdata [英] Jersey 2 injection source for multipart formdata
问题描述
我有一个方法:
@POST
@Consumes("multipart/form-data")
@Produces( {"text/xml"})
public Response processForm(
@FormDataParam("myparam") InputStream is,
@FormDataParam("myparam") FormDataContentDisposition detail)
与泽西岛1.x一起罚款。
which worked fine with Jersey 1.x.
我升级到2.0 m11。
I'm upgrading to 2.0 m11.
现在我收到以下错误:
12/01/2013 11:15:04 AM org.glassfish.jersey.server.ApplicationHandler initialize
INFO: Initiating Jersey application, version Jersey: 2.0-m11 2012-12-21 12:34:15...

SEVERE: The following errors and warnings have been detected:
WARNING: No injection source found for a parameter of type public javax.ws.rs.core.Response com.plutext.FileUpload.processForm(java.io.InputStream,org.glassfish
.jersey.media.multipart.FormDataContentDisposition) at index 0.
我发现 http://java.net/jira/browse/JERSEY-1413 并提交 http://java.net/projects/jersey/lists/commits/archive/2012-09/message/126 这似乎是相关的,但对我来说,解决问题的方法并不明显。
I found http://java.net/jira/browse/JERSEY-1413 and commit http://java.net/projects/jersey/lists/commits/archive/2012-09/message/126 which seems relevant, but its not obvious to me what to do to fix the problem.
更新
我创建了一个servlet,它在org.glassfish.jersey.server.ApplicationHandler初始化之前在Tomcat中运行:
I made a servlet, which runs in Tomcat before org.glassfish.jersey.server.ApplicationHandler initialize:
public class Jersey2Init extends HttpServlet {
private static final Logger jul = Logger.getLogger(Jersey2Init.class
.getName());
static {
System.out.println("\n\nrunning Jersey2Init\n\n");
final ResourceConfig resourceConfig1 = new ResourceConfig(XFormService.class);
resourceConfig1.registerInstances(new LoggingFilter(jul, true));
resourceConfig1.register(MultiPartFeature.class);
final ResourceConfig resourceConfig2 = new ResourceConfig(AssembleService.class);
resourceConfig2.registerInstances(new LoggingFilter(jul, true));
resourceConfig2.register(MultiPartFeature.class);
}
}
它绝对是第一次运行:
INFO: Deploying web application archive C:\Java\apache-tomcat-7.0.29\webapps\Foo-Services.war
running Jersey2Init
18/01/2013 9:09:51 PM org.glassfish.jersey.server.ApplicationHandler initialize

SEVERE: The following errors and warnings have been detected:
但我仍然保持不变错误。
But I still get the same error.
推荐答案
您需要在应用程序上启用MultiPart功能。启用此功能会为Jersey 2应用程序注入必要的邮件正文读取器和编写器。以下是注册方式:
You need to enable MultiPart feature on your application. Enabling this feature injects necessary message body readers, writers to your Jersey 2 application. Here is how you register them:
final ResourceConfig resourceConfig = new ResourceConfig(MultiPartResource.class);
resourceConfig.register(MultiPartFeature.class);
在服务器端(servlet部署):
On the server-side (servlet deployment):
import org.glassfish.jersey.filter.LoggingFilter;
import org.glassfish.jersey.media.multipart.MultiPartFeature;
import javax.ws.rs.core.Application;
import java.util.HashSet;
import java.util.Set;
public class MyApplication extends Application {
@Override
public Set<Class<?>> getClasses() {
final Set<Class<?>> classes = new HashSet<Class<?>>();
// register resources and features
classes.add(MultiPartFeature.class);
classes.add(MultiPartResource.class);
classes.add(LoggingFilter.class);
return classes;
}
}

在客户端:
On the client-side:
final ClientConfig clientConfig = new ClientConfig();
clientConfig.register(MultiPartFeature.class);
Client client = ClientFactory.newClient(clientConfig);
我在Github中整理了一个端到端的Jersey 2 MultiPart示例这里。
I put together an end-to-end Jersey 2 MultiPart sample in Github here.
