上载文件时未找到public javax.ws.rs.core.response类型参数的注入源

Question

我想从ReactJS上传一个文件到Java后端。但它会在我上传的每个文件上添加以下内容：

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

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

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

@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();

警告：在索引3处找不到类型为public javax.ws.rs.core.response pilotage.rest.incidents.incidenteditiqueservice.uploadFile（javax.ws.rs.core.HttpHeaders,java.lang.Integer,java.lang.String,java.io.InputStream）的参数的注入源。

有人能帮帮我吗？

Answer 1

我也犯了同样的错误。错误是由于错误的包导入。确保导入正确的包。我认为这里的问题是因为FormDataParam和PathParam包。这两种软件的正确包是：

1. PathParam-javax.ws.rs.PathParam；
2. FormDataParam-org.glassfish.jersey.media.multipart.FormDataParam；
