无法使用Jax-RS上传文件

Question

我想用泽西框架.我在Java EE7上使用ant应用程序运行Web服务.我的应用服务器是Glassfish

我的方法看起来像这样:

 package mypackage.service;
        ...
         import org.glassfish.jersey.media.multipart.FormDataContentDisposition;
        import org.glassfish.jersey.media.multipart.FormDataParam;

        @POST
        @Path("createSomething")
        @Consumes(MULTIPART_FORM_DATA)
        @Produces(APPLICATION_XML)
        public Response createSomething(@FormDataParam("upload") InputStream is, @FormDataParam("upload") FormDataContentDisposition formData, @QueryParam("some") String some,  @Context HttpServletRequest request) {

            String fileLocation = "C:\\UploadFile\\" + formData.getFileName();

        //more things, do not matter

            try {
                ctrl.saveFile(is, fileLocation);
                String result = "Successfully File Uploaded on the path " + fileLocation;
                return Response.status(Response.Status.OK).entity(result).build();
            } catch (IOException e) {
                e.printStackTrace();
                return Response.status(Response.Status.INTERNAL_SERVER_ERROR).build();

            }

我也有一个应用程序配置:

package mypackage.service;

import java.util.HashSet;
import java.util.Set;
import javax.ws.rs.core.Application;
import org.glassfish.jersey.media.multipart.MultiPartFeature;

@javax.ws.rs.ApplicationPath("")
public class ApplicationConfig extends Application {

    @Override
    public Set<Class<?>> getClasses() {
        final Set<Class<?>> resources = new HashSet<>();
        addRestResourceClasses(resources);
        resources.add(MultiPartFeature.class);

        return resources;

    }

    /**
     * Do not modify addRestResourceClasses() method. It is automatically
     * populated with all resources defined in the project. If required, comment
     * out calling this method in getClasses().
     */
    private void addRestResourceClasses(Set<Class<?>> resources) {
        resources.add(mypackage.service.MYSERVICE.class);


    }

}

在myweb.xml上我有:

<servlet>
    <servlet-name>ServletAdaptor</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>mypackage.service.ApplicationConfig</param-value>
    </init-param>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>mypackage.service</param-value>
    </init-param>
    <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>

    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>ServletAdaptor</servlet-name>
    <url-pattern>/createSomething/*</url-pattern>
</servlet-mapping>

我仍然得到同样的信息:

引起:org.apache.catalina.LifecycleException:org.glassfish.jersey.server.model.ModelValidationException:应用程序初始化期间应用程序资源模型的验证失败.[[FATAL]找不到类型为public javax.ws.rs.core.Response的参数的注入源

我做错了什么？

Answer 1

这对我来说可以。尽管我会完全摆脱应用程序子类。这是不需要的，并且可能会导致冲突/混乱。你的 xml 已经足够配置了，只需去掉javax.ws.rs.Application <init-param>. 我还会考虑将多部分 jar 设为编译时 jar（意味着不内置到战争中 - 它们可能与 Glassfish 的版本冲突）。我很少使用 Ant，所以我不确定如何做到这一点，但我知道这是可能的。
