泽西 2 注入源的多部分表单数据

multipartform-data java jax-rs jersey tomcat7

2022-09-01 11:21:37

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)

这与泽西岛1.x一起工作得很好。

我正在升级到 2.0 m11。

现在我得到以下错误：

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...
12/01/2013 11:15:04 AM org.glassfish.jersey.internal.Errors processErrors
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 这似乎很重要，但对我来说，如何解决问题并不明显。

更新

我做了一个servlet，它在org.glassfish.jersey.server.ApplicationHandler初始化之前在Tomcat中运行：

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);       
    }
}

它肯定是首先运行的：

INFO: Deploying web application archive C:\Java\apache-tomcat-7.0.29\webapps\Foo-Services.war


running Jersey2Init

但我仍然得到同样的错误。

您需要在应用程序上启用多部分功能。启用此功能会将必要的消息正文读取器、写入器注入到您的 Jersey 2 应用程序中。以下是注册它们的方法：

在服务器端（http-server）：

final ResourceConfig resourceConfig = new ResourceConfig(MultiPartResource.class);
resourceConfig.register(MultiPartFeature.class);

在服务器端（servlet 部署）：

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;
    }
}

        <init-param>
            <param-name>javax.ws.rs.Application</param-name>
            <param-value>com.aruld.jersey.multipart.MyApplication</param-value>
        </init-param>

    </servlet>
    <servlet-mapping>
        <servlet-name>Jersey Servlet</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
</web-app>

在客户端：

final ClientConfig clientConfig = new ClientConfig();
clientConfig.register(MultiPartFeature.class);
Client client = ClientFactory.newClient(clientConfig);

我在这里在Github中整理了一个端到端的Jersey 2 MultiPart示例。

答案 2

我试图使用泽西岛2进行文件上传。我想避免创建自定义应用程序或资源配置类来启用 MultiPart。它没有很好的文档记录，但是如果你想添加多部分功能，你所要做的就是将其添加到Web中的Jersey servlet配置中.xml：

<init-param>
    <param-name>jersey.config.server.provider.classnames</param-name>
    <param-value>org.glassfish.jersey.filter.LoggingFilter;org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
</init-param>

如您所见，我还添加了一个日志记录过滤器。
