我正在使用此代码：
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("/files")
public class JerseyFileUpload {
private static final String SERVER_UPLOAD_LOCATION_FOLDER = "C://Users/nikos/Desktop/Upload_Files/";
/**
* Upload a File
*/
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
@FormDataParam("file") InputStream fileInputStream,
@FormDataParam("file") FormDataContentDisposition contentDispositionHeader) {
String filePath = SERVER_UPLOAD_LOCATION_FOLDER
+ contentDispositionHeader.getFileName();
// save the file to the server
saveFile(fileInputStream, filePath);
String output = "File saved to server location : " + filePath;
return Response.status(200).entity(output).build();
}
// save uploaded file to a defined location on the server
private void saveFile(InputStream uploadedInputStream, String serverLocation) {
try {
OutputStream outpuStream = new FileOutputStream(new File(
serverLocation));
int read = 0;
byte[] bytes = new byte[1024];
outpuStream = new FileOutputStream(new File(serverLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
outpuStream.write(bytes, 0, read);
}
outpuStream.flush();
outpuStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
当我尝试在Apache Tomcat上运行它时，我收到以下错误消息：

这是什么意思？我该如何修复这些依赖项？
提前致谢！

部署它时，大多数情况下罐子都没有转移到Tomcat。我可以看到一个问题，就是你遗漏了<packaging>中的pom.xml。如果缺少，则默认为构建.jar。您需要的是.war，其中依赖项被放入WEB-INF/lib。
因此，请在项目<packaging>war</packaging>下添加<version>。清理并打包项目。然后你应该得到一个.war文件。如果您展开.war，则会看到WEB-INF/lib。这是webapp依赖项的标准位置。在没有爆炸的情况下，您可以简单地将战争添加到Tomcat webapp目录，当您启动Tomcat时，它应该爆炸.war并且应该能够在那里找到库。
添加此内容后，运行示例没有问题。
