原因：缺少curator的两个包

解决办法：在pom.xml中添加：

　　　　
                 
      
       org.apache.curator
                  
      
       curator-framework
                  
      
       2.8.0
              
             
                 
      
       org.apache.curator
                  
      
       curator-recipes
                  
      
       2.8.0
