Question

我正在尝试使用MutipartForm数据进行图片上传，我也实现了它。但我的问题是我的其他api方法不适用于Multipart表单数据。我收到了java.lang.ClassNotFoundException：org.glassfish.jersey.server.internal.inject.ExtractorException 我正在使用Fallow jar文件

我正在使用的狂热代码

    @Path("/fileandjson")
public class HelloWorld {
    public static final String UPLOAD_FILE_SERVER = "D:/saveimages/";
    @POST
    @Path("/sample")
    @Produces( MediaType.APPLICATION_JSON)
    public void sample(){
        System.out.println("inside web service ");
    }
    @POST
    @Path("/upload/images")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public Response uploadImageFile(@FormDataParam("uploadFile") InputStream fileInputStream, 
                                    @FormDataParam("uploadFile") FormDataContentDisposition fileFormDataContentDisposition,
                                    @FormDataParam("firstName") String name) {
        String fileName = null;
        String uploadFilePath = null;
        try {
            System.out.println("name : "+name);
            fileName = fileFormDataContentDisposition.getFileName();
            uploadFilePath = writeToFileServer(fileInputStream, fileName);
            System.out.println("fileName : "+fileName+" : uploadFilePath : "+uploadFilePath);
        } 
        catch(IOException ioe){
            ioe.printStackTrace();
        }
        finally{
            // release resources, if any
        }
        return Response.ok("File uploaded successfully at " + uploadFilePath).build();
    }


    private String writeToFileServer(InputStream inputStream, String fileName) throws IOException {

        OutputStream outputStream = null;
        String qualifiedUploadFilePath = UPLOAD_FILE_SERVER + fileName;

        try {
            outputStream = new FileOutputStream(new File(qualifiedUploadFilePath));
            int read = 0;
            byte[] bytes = new byte[1024];
            while ((read = inputStream.read(bytes)) != -1) {
                outputStream.write(bytes, 0, read);
            }
            outputStream.flush();
        } 
        catch (IOException ioe) {
            ioe.printStackTrace();
        }
        finally{
            //release resource, if any
            outputStream.close();
        }
        return qualifiedUploadFilePath;
    }

我遇到了祸患错误。

Answer 1

您正在混合不同的版本，例如你有 jaxrs-ri-2.21.jar 和 jersey-media-multipart-2.12.jar ，但我认为你需要 jersey-media-multipart-2.21.jar

如果上面的提示无法帮助您解决问一般来说，最好显示pom.xml以支持jar文件的名称。）

java.lang.ClassNotFoundException：org.glassfish.jersey.server.internal.inject.ExtractorException
