示例1: create
import org.apache.zookeeper.CreateMode; //导入方法依赖的package包/类
/**
* <pre>
* 1. 使用zookeeper过程，针对出现ConnectionLoss异常，比如进行create/setData/delete，操作可能已经在zookeeper server上进行应用
* 2. 针对SelectStageListener进行processId创建时，会以最后一次创建的processId做为调度id. 如果进行retry，之前成功的processId就会被遗漏了
* </pre>
*
* @see org.apache.zookeeper.ZooKeeper#create(String path, byte[] path, List acl, CreateMode mode)
