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.我的服务类名是:UploadFileService.java(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中的JAR文件:

我尝试启动tomcat服务器时收到以下错误:

通过互联网,我发现有很多示例显示了如何使用RESTFul API上传MULTIPART文件.但同样的解决方案.我也无法运行这些代码.我想我在做JAR文件时出错了.有人可以帮我这个吗？

Answer 1

摆脱jersey-multipart-1.18.jar.这是泽西岛1.x. 加上这两个

• 新泽西媒体多-2.17
• mimepull-1.9.3

对于Maven,您将使用以下依赖项(您不需要显式添加mimepull依赖项,因为这将依赖它).

<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.如果您使用ResourceConfigfor配置,则可以执行此操作

register(MultiPartFeature.class);

如果您使用的是web.xml,则可以将该类添加为<init-param>Jersey servlet

<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,如果您要注册多个提供程序,则可以使用逗号或分号分隔每个提供程序类.你不能param-name两次使用它.见Suarabh的回答

UPDATE

此外,一旦你摆脱了jersey-multipart-1.18.jar你将有丢失的导入类的编译错误.在大多数情况下,类名仍然是相同的,只是包已经改变,即

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

在旁边

如果您来这里是为了另外一个ModelValidationException,这里有一些链接,以获取有关异常的其他原因的信息.

• 1
• 2
• 3

Answer 2

这个非常普遍的错误的另一个可能原因是，当在一个参数上声明了多个工厂时，Jersey 只搜索与最后一个注释关联的工厂。（见错误报告）

在修复此问题之前，如果您正在使用除 之外的任何其他注释@FormDataParam，则它必须放在最后。

这有效：

@NotEmpty @FormDataParam("myParam") String myParam

这不会：

@FormDataParam("myParam") @NotEmpty String myParam

Answer 3

我也有同样的异常。我在 web.xml 中做了以下更改

<init-param>
            <param-name>jersey.config.server.provider.classnames</param-name>
            <param-value>org.glassfish.jersey.filter.LoggingFilter;org.glassfish.jersey.moxy.json.MoxyFeature;org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
        </init-param>

并将球衣 2.7 更改为 2.9。我不知道这 2 的更改解决了问题。
