在Spring Boot应用程序中使用Rackspace时的Apache jclouds java.lang.NoSuchMethodError [英] Apache jclouds java.lang.NoSuchMethodError when using Rackspace in a Spring Boot application
本文介绍了在Spring Boot应用程序中使用Rackspace时的Apache jclouds java.lang.NoSuchMethodError的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试将Apache Jclouds集成到我正在开发的Spring Boot应用程序中，以便可以将文件上传到Rackspace Cloud Files(UK).
I'm trying to integrate Apache Jclouds into a Spring Boot application I'm working on so that I can upload files to Rackspace Cloud Files(UK).
我创建了一个作为Bean创建的类；
I've created a class which I'm creating as a Bean;
import com.google.common.io.ByteSource;
import com.google.common.io.Files;
import org.jclouds.ContextBuilder;
import org.jclouds.io.Payload;
import org.jclouds.io.Payloads;
import org.jclouds.openstack.swift.v1.features.ObjectApi;
import org.jclouds.rackspace.cloudfiles.v1.CloudFilesApi;
import org.springframework.web.multipart.MultipartFile;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
/**
* Class WebStorage
*
*/
public class WebStorage {
private final String region = "lon";
private final String provider = "rackspace-cloudfiles-uk";
private String username;
private String apiKey;
private String container;
private String url;
private CloudFilesApi cloudFilesApi;
public WebStorage(String username, String apiKey, String container, String url) {
this.username = username;
this.apiKey = apiKey;
this.container = container;
this.url = url;
cloudFilesApi = ContextBuilder.newBuilder(provider)
.credentials(this.username, this.apiKey)
.buildApi(CloudFilesApi.class);
}
/**
* Accepts a MultipartFile and returns it as a File
* @param multipartFile the MultiPartFile to convert
* @return a new File
*/
public static File createFileFromMultipart(MultipartFile multipartFile) {
File file = new File(multipartFile.getOriginalFilename());
try {
file.createNewFile();
FileOutputStream fos = new FileOutputStream(file);
fos.write(multipartFile.getBytes());
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
return file;
}
/**
* Send the file to the CDN and return it's full URL
* @param name the path/name of the file on the CDN
* @param theFile the file to upload to the CDN
* @return the full URL to the uploaded file on the CDN
*/
public String put(String name, File theFile) {
ObjectApi objectApi = cloudFilesApi.getObjectApi(region, this.container);
/* Upload the file */
ByteSource byteSource = Files.asByteSource(theFile);
Payload filePayload = Payloads.newByteSourcePayload(byteSource);
objectApi.put(name, filePayload);
return this.url + name;
}
}
我在声明所有其他bean的同一个地方声明了Bean(可以正常工作)；
I'm declaring the bean in the same place I'm declaring all other beans (which work fine);
@Bean
public WebStorage storage() {
return new WebStorage(
env.getProperty("voila.cdn.username"),
env.getProperty("voila.cdn.apikey"),
env.getProperty("voila.cdn.container"),
env.getProperty("voila.cdn.url")
);
}
但是，每次运行该应用程序时，尝试创建Bean时，由于未找到类而导致无法加载Bean.
But each time I run the application, the bean fails to load as a class not found error is generated when trying to create the bean.

我在pom文件中包含了jclouds的1.9.2版本；
I've included version 1.9.2 of jclouds in my pom file;
<dependency>
<groupId>org.apache.jclouds</groupId>
<artifactId>jclouds-all</artifactId>
<version>1.9.2</version>
</dependency>
有人可以告诉我为什么我遇到找不到班级的错误吗?我的POM中没有包含任何Google依赖项，因此其中任何一个依赖项都包含在我的依赖项中.
Is someone able to tell my why I'm getting a class not found error? I'm not including any Google dependencies in my POM, so any that are available are being included by one of my dependencies.
推荐答案
这是jclouds中的一个已知问题.参见 JCLOUDS-1160 和
This is a known issue in jclouds. See JCLOUDS-1160 and JCLOUDS-1166. Until those issues are fixed you won't be able to use jclouds with Spring Boot if you can't force a version of Gson <= 2.5.
另一个选择是使用maven-shade-plugin遮蔽jclouds依赖项并将Gson捆绑在其中.这样，您应该能够使用环境所需的Gson版本，而jclouds使用阴影的版本.
Another option is to use the maven-shade-plugin to shade the jclouds dependencies and bundle Gson in it. This way you should be able to use the Gson version your environment needs, while jclouds uses the shaded one.
这篇关于在Spring Boot应用程序中使用Rackspace时的Apache jclouds java.lang.NoSuchMethodError的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
