sakai和jcloud操作流程

https://github.com/botimer/sakai/tree/master/cloud-content

这里为sakai新建了一种资源，叫做swift文件处理器。用于将文件保存到云中。

1 实现

/**

* The cloud implementation of FileSystemHandler.

* <p/>

* This class read and write files to and from OpenStack-Swift cloud storage.

*

* @author OpenCollab

*/

public class SwiftFileSystemHandler implements FileSystemHandler {

这个类重载接口，并实现了文件的存、取、关、开。

2 打包依赖（impl pom）

<!-- jclouds dependencies -->

<!-- Package these directly in the impl/component -->

<dependency>

<groupId>org.apache.jclouds.driver</groupId>

<artifactId>jclouds-slf4j</artifactId>

<version>${jclouds.version}</version>

<exclusions>

<exclusion>

<groupId>aopalliance</groupId>

<artifactId>aopalliance</artifactId>

</exclusion>

</exclusions>

</dependency>

3 定义bean实体

<!-- These beans are lazy inited as they won't startup unless correctly configured -->

<bean id="org.sakaiproject.content.api.FileSystemHandler.swift" class="coza.opencollab.sakai.cloudcontent.SwiftFileSystemHandler"

init-method="init" destroy-method="destroy" lazy-init="true">

</bean>

4 定义pack （pack pom）

<name>Sakai Cloud Resources Components</name>

<groupId>org.sakaiproject.content</groupId>

<artifactId>cloud-content-pack</artifactId>

<packaging>sakai-component</packaging>

<properties>

<deploy.target>components</deploy.target>

</properties>

<dependencies>

<dependency>

<groupId>org.sakaiproject.content</groupId>

<artifactId>cloud-content-impl</artifactId>

<version>${project.version}</version>

</dependency>

</dependencies>

在使用的时候使用方法

5 定义使用该类替代传统的文件处理 sakai-configuration.xml

<beans>
  <!-- Swift handler -->
  <alias name="org.sakaiproject.content.api.FileSystemHandler.swift" alias="org.sakaiproject.content.api.FileSystemHandler" />

  <!-- Generic BlobStore handler, currently only for AWS S3 -->
  <!-- <alias name="org.sakaiproject.content.api.FileSystemHandler.blobstore" alias="org.sakaiproject.content.api.FileSystemHandler" /> -->
</beans>

6 定义实现中的一些值的属性

[email protected]     = http://swift.server:5000/v2.0/
[email protected]     = tenant:username
[email protected]   = password
[email protected]       = RegionOne
useIdForPath@org.sakaiproject.content.api.FileSystemHandler.swift = true

provider@org.sakaiproject.content.api.FileSystemHandler.blobstore      = aws-s3
identity@org.sakaiproject.content.api.FileSystemHandler.blobstore      = <S3 Access Key ID>
credential@org.sakaiproject.content.api.FileSystemHandler.blobstore    = <S3 Secret Access Key>
baseContainer@org.sakaiproject.content.api.FileSystemHandler.blobstore = your-bucket-name
useIdForPath@org.sakaiproject.content.api.FileSystemHandler.blobstore  = true

[email protected]=/content/live/
bodyPathDeleted@org.sakaiproject.content.api.ContentHostingService=/content/deleted/

例如region对应实现里面的

/**

* The region to connect to.

*/

public void setRegion(String region) {

this.region = region;

}
