问题描述

我正在使用基于 Jersey 的 restful 服务实现策略来构建一个将用于上传文件的服务.我的服务类名称是:UploadFileService.java(见下面的代码)

 包 com.jerser.service;导入 java.io.File;导入 java.io.FileOutputStream;导入 java.io.IOException;导入 java.io.InputStream;导入 java.io.OutputStream;导入 javax.ws.rs.Consumes;导入 javax.ws.rs.POST;导入 javax.ws.rs.Path;导入 javax.ws.rs.core.MediaType;导入 javax.ws.rs.core.Response;导入 com.sun.jersey.core.header.FormDataContentDisposition;导入 com.sun.jersey.multipart.FormDataParam;@Path("/文件上传")公共类 UploadFileService {@邮政@Path("/上传")@Consumes(MediaType.MULTIPART_FORM_DATA)公共响应上传文件(@FormDataParam("file") InputStream UploadInputStream,@FormDataParam("file") FormDataContentDisposition fileDetail) {String uploadFileLocation = "d://uploaded/" + fileDetail.getFileName();//保存writeToFile(uploadedInputStream, UploadedFileLocation);String output = "文件上传到:" + UploadedFileLocation;返回 Response.status(200).entity(output).build();}//将上传的文件保存到新位置private void writeToFile(InputStream UploadInputStream,字符串上传文件位置) {尝试 {OutputStream out = new FileOutputStream(new File(上传文件位置));int 读 = 0;字节[]字节=新字节[1024]；out = new FileOutputStream(new File(uploadedFileLocation));while ((read = UploadInputStream.read(bytes)) != -1) {out.write(bytes, 0, read);}out.flush();关闭()；} catch (IOException e) {e.printStackTrace();}}}

这些是我的库中的 JAR 文件:

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.但使用相同的解决方案.我也无法运行这些代码.我想我对 JAR 文件做错了.有人可以帮我吗?

解决方案

去掉jersey-multipart-1.18.jar.这适用于 Jersey 1.x.添加这两个

对于 Maven，您将使用以下依赖项(您无需显式添加 mimepull 依赖项，因为这会将其拉入).

<groupId>org.glassfish.jersey.media</groupId><artifactId>jersey-media-multipart</artifactId><version>2.17</version><!-- 确保 Jersey 版本匹配您当前正在使用的那个 --></依赖>

然后你需要注册MultiPartFeature.如果您使用 ResourceConfig 进行配置，则只需执行

register(MultiPartFeature.class);

如果您使用的是 web.xml，那么您可以将该类作为 <init-param> 添加到 Jersey servlet

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

请注意，如果您有多个要注册的提供程序，则可以使用逗号、分号或空格/换行符分隔每个提供程序类.您不能两次使用相同的 param-name.参见 Suarabh 的回答

更新

此外，一旦您摆脱了 jersey-multipart-1.18.jar，您将遇到缺少的导入类的编译错误.大多数情况下，类名仍然相同，只是包发生了变化，即

对于 Dropwizard

如果您使用 Dropwizard，而不是添加 jersey-media-multipart，他们会记录您添加 dropwizard-forms.而不是注册 MultiPartFeature，你应该注册 MultiPartBundle

@Override公共无效初始化(引导<示例配置>引导){bootstrap.addBundle(new MultiPartBundle());}

实际上并没有太大区别，因为 Dropwizard 包所做的只是将 MultiPartFeature 注册到 ResourceConfig.

旁白

如果您在这里遇到不同的 ModelValidationException，这里有一些链接，可以了解有关其他异常原因的信息.

I am using Jersey based restful Service implementation strategy to build a service which will be used to upload files. My service class name is : UploadFileService.java (See Code below)

 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();
        }

    }

}

Over the internet I found there are plenty of example which shows How to upload MULTIPART file using RESTFul API. But with same solution. I am not able to run those code as well. I think I am doing something wrong with the JAR files. Could anyone please help me on this?

解决方案

Get rid of jersey-multipart-1.18.jar. That is for Jersey 1.x. Add these two

For Maven you would use the following dependency (you don't need to explicitly add the mimepull dependency, as this one will pull it in).

<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>

Then you need to register the MultiPartFeature. If you are using a ResourceConfig for configuration, you can simply do

register(MultiPartFeature.class);

If you are using web.xml, then you can add the class as an <init-param> to the 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>

Note that if you have multiple providers that you want to register, then you can delimit each provider class with a comma, semicolon, or space/newline. You cannot use this same param-name twice. See Suarabh's answer

UPDATE

Also, once you get rid of jersey-multipart-1.18.jar you will have compile errors for the missing imported classes. For the most part, the class names are still the same, just the packages have changed, i.e.

For Dropwizard

If you're using Dropwizard, instead of adding the jersey-media-multipart, they document for your to add dropwizard-forms instead. And instead of registering the MultiPartFeature, you should register the MultiPartBundle

@Override
public void initialize(Bootstrap<ExampleConfiguration> bootstrap) {
    bootstrap.addBundle(new MultiPartBundle());
}

Really doesn't make much difference though as all the Dropwizard bundle does is register the MultiPartFeature with the ResourceConfig.

Aside

If you are here for a different ModelValidationException, here are some links for information on other causes of the exception.
