使用 Jersey 通过 RESTfull 服务上传文件和资源配置不可修改? [英] Uploading file using Jersey over RESTfull service and The resource configuration is not modifiable?

问题描述

@Path("file.upload")
public class UploadFileService {
@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
        @FormDataParam("file") InputStream uploadedInputStream,
        @FormDataParam("file") FormDataContentDisposition fileDetail) {

    System.out.println("-----------------UploadFileService------------------1.");
    // Should we use a disk or DB? Decided to use DISK
    // Path should be read from properties-files
    String uploadedFileLocation = "//uploaded/" + fileDetail.getFileName();

    // save it
    writeToFile(uploadedInputStream, uploadedFileLocation);

    String output = "File uploaded to : " + uploadedFileLocation;
    // All went OK
    return Response.status(200).entity(output).build();

}

我在 UploadFileService 下实现了这样的测试服务:

I implemented test service like this under the UploadFileService:

@GET
@Path("count")
@Produces("text/plain")
public String countREST() {
    return "1 one 1";
}

我得到了这个异常记录:

and I got this exception to log:

FINE:   [Web-Security] hasResource perm: ("javax.security.jacc.WebResourcePermission" 

"/webresources/file.upload/count" "GET")

环境

• Netbeans7.3.1
• Glassfish 4.0
• 带有 Glassfish 4.0 的泽西 2

推荐答案

为了在您的 Jersey 应用程序中使用 multipart，您需要注册 MultiPartFeature 在您的应用程序中，即:

In order to use multipart in your Jersey application you need to register MultiPartFeature in your application, i.e.:

public class ApplicationConfig extends Application {

    public Set<Class<?>> getClasses() {
        final Set<Class<?>> resources = new HashSet<Class<?>>();

        // Add your resources.
        resources.add(UploadFileService.class);

        // Add additional features such as support for Multipart.
        resources.add(MultiPartFeature.class);

        return resources;
    }
}

有关详细信息，请参阅 Jersey 用户指南中的 Multipart 部分.

For more information see Multipart section in the Jersey Users Guide.

对于您面临的第二个问题，请尝试重新启动 GlassFish 服务器，我不确定 NetBeans 在更改后如何重新加载 Jersey 应用程序(如果这没有帮助，请发布您的 ApplicationConfig).

For the second issue you're facing try to restart the GlassFish server, I am not sure how NetBeans are reloading the Jersey app after a change (if this doesn't help, please post your ApplicationConfig).
