上传文件时找不到公共 javax.ws.rs.core.Response 类型参数的注入源

Question

我想将文件从 ReactJS 上传到 Java 后端。但它会在我上传的每个文件中添加这个：

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

而且我再也无法打开它们了。

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

没有为 public javax.ws.rs.core.Response 类型的参数找到注入源

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();

这是我的 web.xml：

我只得到这一行：

警告：未找到公共类型参数的注入源 javax.ws.rs.core.Response Pilotage.rest.incidents.IncidentEditiqueService.uploadFile(javax.ws.rs.core.HttpHeaders,java.lang.Integer,java.lang.String,java.io.InputStream) 在索引 3。

有人可以帮我吗？

Answer 1

我有同样的错误。该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。这两个的正确包是：

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