如何使用JDBC騾標準重新連接策略

Question

我想用騾子JDBC標準重新連接策略....對於我用下面的代碼： -

<jdbc-ee:connector name="Database_Global" dataSource-ref="DB_Source" validateConnections="true" queryTimeout="-1" pollingFrequency="0" doc:name="Database"> 
     <jdbc-ee:query key="InsertQuery" value="INSERT INTO getData(ID,NAME,AGE,DESIGNATION)VALUES(?,?,?,?)"/> 
     <jdbc-ee:query key="RetriveQuery" value="Select * from getData where ID=?"/> 

<reconnect frequency="2000" blocking="false" count="5"/> 
</jdbc-ee:connector> 

現在，當過我嘗試啓動我的騾子應用我收到以下異常： -

org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'reconnect'. One of '{"http://www.mulesoft.org/schema/mule/jdbc":abstract-query, "http://www.mulesoft.org/schema/mule/ee/jdbc":sqlCommandExecutorFactory, "http://www.mulesoft.org/schema/mule/ee/jdbc":ackSqlCommandExecutorFactory, "http://www.mulesoft.org/schema/mule/ee/jdbc":sqlCommandRetryPolicyFactory}' is expected.

現在我的問題是如何使用重新連接策略騾子JDBC，這樣我可以處理，只要數據庫服務器已關閉....請幫助

嘗試把recconect作爲第一要素：

<jdbc-ee:connector name="Database_Global" dataSource-ref="DB_Source" validateConnections="true" queryTimeout="-1" pollingFrequency="0" doc:name="Database"> 
     <reconnect frequency="2000" blocking="false" count="5"/> 
     <jdbc-ee:query key="InsertQuery" value="INSERT INTO getData(ID,NAME,AGE,DESIGNATION)VALUES(?,?,?,?)"/> 
     <jdbc-ee:query key="RetriveQuery" value="Select * from getData where ID=?"/> 
</jdbc-ee:connector>
