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

问题描述

@POST $ b $ @Consumes（MediaType.MULTIPART_FORM_DATA）
public Response uploadFile（
@FormDataParam（file）InputStream uploadedInputStream，
@FormDataParam（file）FormDataContentDisposition fileDetail）{

System.out.println（ - --------------- UploadFileService ------------------ 1）。
//我们应该使用磁盘还是数据库？决定使用DISK
//路径应该从属性文件读取
String uploadedFileLocation =// uploaded /+ fileDetail.getFileName（）;

//保存
writeToFile（uploadedInputStream，uploadedFileLocation）;

字符串输出=文件上传到：+ uploadedFileLocation;
//一切就OK
返回Response.status（200）.entity（输出）.build（）;

$ b

环境

• Netbeans7.3.1


• Glassfish 4.0

使用Glassfish 4.0的Jersey 2

解决方案

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

  public class ApplicationConfig extends Application {
 
 public Set< Class<？>> getClasses（）{
 final Set< Class<>> resources = new HashSet< Class<>>（）; 
 
 //添加您的资源。 
 resources.add（UploadFileService.class）; 
 
 //添加其他功能，如对Multipart的支持。 
 resources.add（MultiPartFeature.class）; 
 
返回资源; 
 
 
 
 
 $ b $ p 
 $ b 
欲了解更多信息，请参阅 Jersey用户指南中的Multipart部分。
 
 
 <对于你面临的第二个问题，尝试重新启动GlassFish服务器，我不确定NetBeans如何在更改后重新加载Jersey应用程序（如果这没有帮助，请将您的 ApplicationConfig ）。
 
@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();

}

Environment


Netbeans7.3.1
Glassfish 4.0
Jersey 2 with Glassfish 4.0

解决方案
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;
    }
}
For more information see Multipart section in the Jersey Users Guide.

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).
