　　tomcat啓動完了以後，一直不停的打印這種錯誤信息，看表面上，應該是zk節點下的數據是空的，鏈接不上服務，因此一直在嘗試鏈接，而後一直又連不上；java

完整的錯誤信息：apache

　　緣由：又是爲了一己之私，省事兒，把服務上的WEB-INFO無情刪除，而後用jenkins打包後，就一直有這個問題了，很無奈，找了個大牛給瞅了瞅，說zk一直在嘗試連我本地的zk，說明服務上是否是少了一些zk的配置文件呢？大牛給了我提示，我就去classes下看配置文件，和本地的對比了下，果真，少了一個dsf.properties的配置文件，裏面就有zk的一些配置，而後手動把這個配置文件給添加到服務上，重啓了下，啓動成功了！原來這個配置文件是經過提交checklist手動添加的，jenkins不會自動的給打進去，致使了這個尷尬的問題，不過好歹解決了，內心仍是鬆了一口氣的！tomcat

　　配置文件內容以下，應該都是一些dsf的配置項：session
