类名称：ZKUtil
方法名：createSetData

ZKUtil.createSetData介绍

[英]Set data into node creating node if it doesn't yet exist. Does not set watch.
[中]如果数据还不存在，则将其设置为节点创建节点。不定表。

代码示例

/**
  * Store the rpc throttle value.
  * @param enable Set to <code>true</code> to enable, <code>false</code> to disable.
  * @throws IOException if an unexpected io exception occurs
  */

   byte[] upData = Bytes.toBytes(enable);
   ZKUtil.createSetData(zookeeper, rpcThrottleZNode, upData);
  } catch (KeeperException e) {
