在Spring Boot中使用Jersey进行文件上传时遇到400错误请求 [英] Using Jersey in Spring Boot for file upload getting 400 Bad Request

问题描述

我尝试了很多使用jersey上传文件的示例.我可以使用@ RequestMapping，ResponseEntity而不是@Path等使其与纯Spring一起使用.但是我想使用jersey，因为我的所有其他端点都由jersey处理.

I have tried a large number of examples for doing file upload with jersey. I can get it to work with pure Spring using @RequestMapping, ResponseEntity instead of @Path etc. But I want to use jersey, as all of my other endpoints are handled by jersey.

更新:我觉得我无法传递表单数据，文件或文本.甚至@FormDataParam("directory") String directory的单个FormDataParam也会发出错误的请求

UPDATE: I feel that I'm unable to pass an form data, file or text. Even a single FormDataParam of @FormDataParam("directory") String directory gives the bad request

我有以下课程

@Component
@Path("/v1.0")
public class FileOperationsResource  {

    private ConfigurationReader mConfigReader;

    @Autowired
    public FileOperationsResource(ConfigurationReader configurationReader) {
        mConfigReader = configurationReader;
    }

   @POST
   @Path("/file/upload")
   @Consumes(MediaType.MULTIPART_FORM_DATA)
   public Response uploadFile(@QueryParam("dir") String directory,
                              @FormDataParam("file") InputStream file,
                              @FormDataParam("file") FormDataContentDisposition fileDisposition) {

我已将以下行添加到我的ResourceConfig

I have added the following line to my ResourceConfig

register(MultiPartFeature.class);

我添加了以下Maven依赖项，但未添加版本，因为我的理解是它将自动拉出与我的spring版本兼容的版本，并且我发现较新的版本不再允许我在其中添加注册ResourceConfig，因为MultiPartFeature丢失.

I have added the following maven dependency, but have not added a version as my understanding is that it will automatically pull the version that works with my version of spring, and I have found newer versions no longer allow me to add register in ResourceConfig as MultiPartFeature is missing.

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-multipart</artifactId>
</dependency>

当我拨打以下电话时，我收到了400错误请求.我觉得我一定打错了电话，或者没有将其他东西连上.任何帮助将不胜感激.

When I make the following call, I get a 400 Bad Request. I feel like I must be making the call wrong, or have failed to wire something else in. Any help would be appreciated.

响应:

{
    "timestamp": "2018-04-20T15:51:01.790+0000",
    "status": 400,
    "error": "Bad Request",
    "message": "Bad Request",
    "path": "/api/v1.0/file/upload"
}

我已经通过Postman进行了呼叫，并使用了表单，并且在接下来的呼叫中使用curl进行了

I've made the call with Postman and using forms, as well as curl with the following call

curl --verbose --form file=@"settings.xml" http://localhost:8080/api/v1.0/file/upload?dir=MyDir

推荐答案

您在application.properties中将spring.jersey.type设置为什么?我可以使用Jersey和Boot上传文件，我相信这是您需要的:

What is your spring.jersey.type set to in application.properties? I have file upload working with Jersey and Boot, I believe this is what you need:

# JERSEY
spring.jersey.type=servlet
spring.jersey.servlet.load-on-startup=1

出于示例目的，这是我的端点:

For example purposes, here's my endpoint:

@POST
@Path("/file/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(@FormDataParam("file") InputStream fileInputStream,
                           @FormDataParam("file") FormDataContentDisposition fileDisposition) {

    String fileName = fileDisposition.getFileName();
    StringBuilder fileContents = new StringBuilder();
    int read = 0;
    int totalBytesRead = 0;
    byte[] bytes = new byte[1024];
    try {
        while ((read = fileInputStream.read(bytes)) != -1) {
            ...save file...
        }
    } catch (IOException e) {
        mLogger.error(e.getMessage(), e);
    }

    return Response.ok().build();
}
