回应：
HTTP状态400 - 错误请求
相同的代码正在使用html表单，但在postman中它投掷了400个BAD REQUEST，我在google上查找解决方案并发现边界丢失，如何解决？因为我必须通过Jquery和rest客户端从移动应用程序和Web客户端等多个客户端接收文件 .
@Path("/file")
public class UploadFileService {
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(@FormDataParam("file") InputStream uploadedInputStream,
@FormDataParam("file") FormDataContentDisposition fileDetail) {
try {
String uploadedFileLocation = "/home/nash/" + fileDetail.getFileName();
// save it
writeToFile(uploadedInputStream, uploadedFileLocation);
String output = "File uploaded to : " + uploadedFileLocation;
System.out.println("File uploaded..........");
return Response.status(200).entity(output).build();
} catch (Exception e) {
e.printStackTrace();
System.out.println("Exception " + e);
return null;
}
}
// save uploaded file to new location
private void writeToFile(InputStream uploadedInputStream, String uploadedFileLocation) {
try {
OutputStream out = new FileOutputStream(new File(uploadedFileLocation));
int read = 0;
byte[] bytes = new byte[1024];
out = new FileOutputStream(new File(uploadedFileLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

请按以下步骤操作：
添加jersey-multipart依赖项 .
在您的应用程序类中（或在
web.xml中）启用MultipartFeature.class.DO NOT 在邮递员请求中添加Content-Type标头 .
对我来说，上述步骤有效 . 如果这对你有帮助，请告诉我 .
