我试图在drop wizard 0.7.1中进行多部分文件上传工作。根据一个例子，我看到我添加了：
'io.dropwizard:dropwizard-forms:0.7.1',
到我的gradle文件。然后我创建以下资源：
import com.path.to.service;
import com.sun.jersey.api.MessageException;
import com.sun.jersey.core.header.FormDataContentDisposition;
import com.sun.jersey.multipart.FormDataParam;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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 java.io.*;
@Path("/api/v1/files")
@Api("/api/v1/files")
public class FileUploadResource {
private static Logger logger = LoggerFactory.getLogger(FileUploadResource.class);
private final MyService myService;
public FileUploadResource(MyService myService) {
this.myService = myService;
}
@POST
@Path("/upload" )
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(@FormDataParam("file") InputStream uploadedInputStream,
@FormDataParam("file") FormDataContentDisposition fileDetail) throws MessageException, IOException {
return myService.process(uploadedInputStream, fileDetail);
}
}
我在主要应用程序中将资源添加到了jersey，就像我的其他资源一样：
MyService myService = new MyService();
environment.jersey().register(new FileUploadResource(myService));
当我从IntelliJ启动应用程序时，我没有任何问题...我可以整天上传文件，没有任何错误或问题。但是，当我构建它并从命令行启动它时，启动时会出现运行时错误。我已经阅读了一些内容，我可能需要按类别注册资源，但在这种情况下，我不知道为什么它可以通过我的IDE工作。此外，对于＆＃39;表格＆＃39;以及它们在下拉向导0.7.x中的大量支持似乎也不像。模块。好像我错过了一些基本的东西。这是错误：

答案 0 :(得分：0)
原来这是gradle插件阴影的一个问题，切换到另一个打包工具（使用不同的类加载器）立即解决了我的问题。
