六、java操作swift对象存储（resultful方式实现）
上一节讲了如何通过swift官方的样例操作swift对象存储，官方样例中，种类还是有点少工作中不够用，但是swift集群的调用支持resultful这就给我们提供了另一种调用swift的方法。那么都支持那些操作类型呢请看下表。
一、 RESTful API 总结
资源类型 URL GET PUT POST DELETE HEAD
账户 /account/ 获取容器列表 - - - 获取账户元数据
容器 /account/container 获取对象列表 创建容器 更新容器元数据 删除容器 获取容器元数据
对象 /account/container/object 获取对象内容和元数据 创建、更新或拷贝对象 更新对象元数据 删除对象 获取对象元数据
了解了以上知识后下面进入代码部分java使用resultful方式操作swift对象存储。
二、pom.xml依赖
