Question

这是我上传文件的原因

@POST
@Path("/uploadFile")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.TEXT_PLAIN)
public Response uploadFileSuite(@HeaderParam("Access-Control-Allow-Origin")
                                @FormParam("file") InputStream uploadedInputStream, 
                                @FormDataParam("file") FormDataContentDisposition fileDetail,
                                @QueryParam("key") String key)  { 
    //path = global variable
    String uploadedFileLocation = PATH + fileDetail.getFileName();
    // save it
    writeToFile(uploadedInputStream, uploadedFileLocation);
    String output = "File uploaded to : " + uploadedFileLocation;
    return Response.status(200).entity(output).build();
 }

然而，当我尝试编译时，我不断收到以下错误：

  SEVERE: Missing dependency for method public javax.ws.rs.core.Response Project.MyResource.uploadFile(java.io.InputStream,com.sun.jersey.core.header.FormDataContentDisposition,java.lang.String) at parameter at index 0
  SEVERE: Missing dependency for method public javax.ws.rs.core.Response Project.MyResource.uploadFile(java.io.InputStream,com.sun.jersey.core.header.FormDataContentDisposition,java.lang.String) at parameter at index 1

我尝试了一切来修复它，但似乎没有任何效果。

非常感谢任何帮助。

这是我的pom.xml

看起来你在一个参数上有两个参数注释：

@HeaderParam("Access-Control-Allow-Origin")
@FormParam("file") InputStream uploadedInputStream,

应该是：

@HeaderParam("Access-Control-Allow-Origin") String origin,
@FormParam("file") InputStream uploadedInputStream,

Jersey REST + Grizzly Web服务，上传文件错误
