我正在使用基于 Jersey 的 Restful 服务实现策略来构建一个用于上传文件的服务。
我的服务类名称是：UploadFileService.java（参见下面的代码）
package com.jerser.service;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import com.sun.jersey.core.header.FormDataContentDisposition;
import com.sun.jersey.multipart.FormDataParam;
@Path("/fileUpload")
public class UploadFileService {
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
@FormDataParam("file") InputStream uploadedInputStream,
@FormDataParam("file") FormDataContentDisposition fileDetail) {
String uploadedFileLocation = "d://uploaded/" + fileDetail.getFileName();
// save it
writeToFile(uploadedInputStream, uploadedFileLocation);
String output = "File uploaded to : " + uploadedFileLocation;
return Response.status(200).entity(output).build();
}
// save uploaded file to new location
private void writeToFile(InputStream uploadedInputStream,
String uploadedFileLocation) {
try {
OutputStream out = new FileOutputStream(new File(
uploadedFileLocation));
int read = 0;
byte[] bytes = new byte[1024];
out = new FileOutputStream(new File(uploadedFileLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
这些是我的库中的 JAR 文件：

当我尝试启动 Tomcat 服务器时，出现以下错误：
org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization.

在互联网上，我发现有很多示例展示了如何使用 RESTFul API 上传 MULTIPART 文件。但使用相同的解决方案。我也无法运行这些代码。
我认为我对 JAR 文件做错了什么。有人可以帮我解决这个问题吗？
