私はこれで正確な問題を把握することができません、誰もこれで私を助けることができますか？

Answer 1

 I got the solution for this 

     1) I have changed sequence of components scan in applicationContext.xml 
from 

    <elasticsearch:repositories base-package="com.elastic.repository"/> 
    <elasticsearch:repositories base-package="com.elastic.entity"/> 
    <context:component-scan base-package="com.elastic" /> 

    to 

    <context:component-scan base-package="com.elastic" /> 
    <elasticsearch:repositories base-package="com.elastic.repository" /> 
    <elasticsearch:repositories base-package="com.elastic.entity" /> 


Base package should come first .
