我正在使用基于 Jersey 的 Restful 服务实现策略来构建一个用于上传文件的服务。我的服务类名称是: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();
}

}

}

这些是我的库中的 JAR 文件:

aopalliance-repackaged-2.4.0-b10.jar

当我尝试启动 Tomcat 服务器时,出现以下错误:

org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization.

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。我认为我对 JAR 文件做错了什么。有人可以帮我解决这个问题吗?

最佳答案

摆脱jersey-multipart-1.18.jar 。这是针对 Jersey 1.x 的。添加这两个

对于 Maven,您将使用以下依赖项(您不需要显式添加 mimepull 依赖项,因为这个依赖项会将其引入)。

<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>

那么你需要注册MultiPartFeature 。如果您使用的是ResourceConfig对于配置,您可以简单地执行

register(MultiPartFeature.class);

如果您使用 web.xml,则可以将该类添加为 <init-param>到 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,如果您想要注册多个提供程序,则可以使用逗号、分号或空格/换行符分隔每个提供程序类。您不能使用相同的 param-name两次。请参阅Suarabh's answer

更新

此外,一旦你摆脱 jersey-multipart-1.18.jar对于缺少的导入类,您将出现编译错误。在大多数情况下,类名仍然相同,只是包发生了变化,即

对于 Dropwizard

如果您使用 Dropwizard,则不要添加 jersey-media-multipart ,他们为您添加文档dropwizard-forms反而。而不是注册 MultiPartFeature ,您应该注册MultiPartBundle

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

实际上并没有多大区别,因为 Dropwizard bundle 所做的只是注册 MultiPartFeatureResourceConfig .

旁白

如果您来这里是为了不同的ModelValidationException ,这里有一些有关异常其他原因的信息的链接。
