Error with file upload in jersey
原标题:Error with file upload in jersey

我正在制作一个使用女岛的超载文件索引。

 @Path("/api")
 public class GreetingService {

     @POST
             @Path("/upload")
      @Consumes("multipart/form-data")
     //@Produces("text/plain")
     public String uploadFile(@FormParam("file") File file, @FormParam("file")    FormDataContentDisposition fcdsFile) {
      String fileLocation = "/files/" + fcdsFile.getFileName();
      //File destFile = new File(fileLocation);  

      return "1";

} }

When I do curl -v -X POST --form [email protected] url I get

       SEVERE: Servlet.service() for servlet ServletAdaptor threw exception
     java.lang.NullPointerException for this line    String fileLocation = "/files/" + fcdsFile.getFileName();

哪里会错?

问题回答

这就是你如何发出呼吁

@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA) // same as "multipart/form-data"
//@Produces("text/plain")
public String uploadFile(
    @FormDataParam("file") InputStream file,
    @FormDataParam("file") FormDataContentDisposition fileDetail
){
    doSomething();
}

我认为,你应当把第2句改为第2句。

@FormDataParam("file") FormDataContentDisposition fcdsFile
