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

Question

我正在使用基于Jersey的Restful Service实施策略来构建将用于上传文件的服务。我的服务类名称是：UploadFileService.java（请参见下面的代码）

 package com.jerser.service;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import com.sun.jersey.core.header.FormDataContentDisposition;
import com.sun.jersey.multipart.FormDataParam;

@Path("/fileUpload")
public class UploadFileService {

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

        String uploadedFileLocation = "d://uploaded/" + fileDetail.getFileName();

        // save it
        writeToFile(uploadedInputStream, uploadedFileLocation);

        String output = "File uploaded to : " + uploadedFileLocation;

        return Response.status(200).entity(output).build();

    }

    // 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();
        }

    }

}

这些是我在lib中拥有的JAR文件：

尝试启动tomcat服务器时出现以下错误：

在互联网上，我发现有很多示例，展示了如何使用RESTFul API上传MULTIPART文件。但是有相同的解决方案。我也无法运行这些代码。我认为我对JAR文件做错了。有人可以帮我吗？

Answer 1

摆脱jersey-multipart-1.18.jar。就是说Jersey1.x。加上这两个

• jersey-media-multipart-2.17
• mimepull 1.9.3

对于Maven，你将使用以下依赖关系（你无需显式添加mimepull依赖关系，因为该依赖关系会将其引入）。

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-multipart</artifactId>
    <version>2.17</version> <!-- Make sure the Jersey version matches
                                 the one you are currently using -->
</dependency>

然后，你需要注册MultiPartFeature。如果你使用ResourceConfigfor进行配置，则只需执行

register(MultiPartFeature.class);

如果你使用的是web.xml，则可以将类作为添加 到Jersey servlet中。

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

请注意，如果你要注册多个提供程序，则可以用逗号或分号分隔每个提供程序类。你不能重复使用param-name两次。见Suarabh的回答

UPDATE

同样，一旦摆脱了，jersey-multipart-1.18.jar你将为缺少的导入类产生编译错误。在大多数情况下，类名称仍然相同，只是包已更改，即

• org.glassfish.jersey.media.multipart.FormDataParam
• org.glassfish.jersey.media.multipart.FormDataContentDisposition
