上载文件时未找到类型为public javax.ws.rs.core.Response的参数的注入源

Question

我想将文件从ReactJS上传到Java后端。但这会将它添加到我上传的每个文件中：

------WebKitFormBoundaryu43OXGtsQPsxs0nM
Content-Disposition: form-data; name="file"; filename="lolo.png"
Content-Type: image/png

而且我无法打开它们。

然后我尝试使用@FormDataParam，但是在部署我的应用程序时出现此错误：

找不到类型为public javax.ws.rs.core.Response的参数的注入源]] >>

我已经尝试添加这些依赖项：

        <dependency>
            <groupId>org.glassfish.jersey.media</groupId>
            <artifactId>jersey-media-multipart</artifactId>
            <version>2.30</version>
        </dependency>
        <dependency>
            <groupId>org.jvnet.mimepull</groupId>
            <artifactId>mimepull</artifactId>
            <version>1.9.3</version>
        </dependency>
        <dependency>
            <groupId>commons-fileupload</groupId>
            <artifactId>commons-fileupload</artifactId>
            <version>1.4</version>
        </dependency>

这是我的前端功能：

const formData = new FormData();
      formData.append('file', file);

axios.post("/pj/"+incident.id +"/"+ file.name, formData);

这是我的后端功能：

@Path("/pj/{idIncident}/{fileName}")
    @POST
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public Response uploadFile(@javax.ws.rs.core.Context HttpHeaders headers, @NotNull @PathParam("idIncident") Integer idIncident, @PathParam("fileName") String fileName, @FormDataParam("file") InputStream file){
        try {


            File theDir = new File("./myFolder/");
            if (!theDir.exists()) {
                theDir.mkdir();
            }


                String target = "./myFolder/"+fileName ;
                OutputStream out = null;
                int read = 0;
                byte[] bytes = new byte[1024];
                out = new FileOutputStream(new File(target));
                while ((read = file.read(bytes)) != -1) {
                    out.write(bytes, 0, read);
                }
                out.flush();
                out.close();

我也试图在我的web.xml中添加它：

<init-param>
    <param-name>jersey.config.server.provider.classnames</param-name>
    <param-value>org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
</init-param>

有人可以帮我吗？
