问题描述
我想用 jax-rs 上传文件。我启动 tomcat,然后从邮递员发送请求,但是,我得到了以下异常。我尝试更改 resteasy 依赖项,但没有解决我的问题。
Failed executing POST files/upload
org.jboss.resteasy.spi.InternalServerErrorException: Bad arguments passed to public javax.ws.rs.core.Response
下面是我的上传类。
@Path("/files")
public class FileUpload {
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
@FormDataParam("file") InputStream uploadedInputStream,@FormDataParam("file") FormDataContentdisposition fileDetail) {
String fileLocation = "/home/" + fileDetail.getFileName();
//saving file
try {
FileOutputStream out = new FileOutputStream(new File(fileLocation));
int read = 0;
byte[] bytes = new byte[1024];
out = new FileOutputStream(new File(fileLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
out.write(bytes,read);
}
out.flush();
out.close();
} catch (IOException e) {e.printstacktrace();}
String output = "File successfully uploaded to : " + fileLocation;
return Response.status(200).entity(output).build();
}
}
pom.xml 文件如下。我很困惑,这是依赖关系的问题。
