Question

我试图调用一个mysql存储过程，它将使用mule返回字符串值。我是骡子的新手，我使用的是Mule 3.4.2企业版。

我的配置代码是：

<jdbc-ee:mysql-data-source name="MySQL_Data_Source"
    user="root" password="root" url="jdbc:mysql://localhost:3306/MULE_POC"
    transactionIsolation="UNSPECIFIED" doc:name="MySQL Data Source"></jdbc-ee:mysql-data-source>
<jdbc-ee:connector name="Database" dataSource-ref="MySQL_Data_Source"
    validateConnections="true" queryTimeout="-1" pollingFrequency="0"
    doc:name="Database"></jdbc-ee:connector>
<data-mapper:config name="map_to_csv"
    transformationGraphPath="map_to_csv.grf" doc:name="map_to_csv"></data-mapper:config>

<flow name="stored_procedure_pocFlow1" doc:name="stored_procedure_pocFlow1">
    <http:inbound-endpoint exchange-pattern="request-response"
        host="localhost" port="4566" doc:name="HTTP" path="mani"></http:inbound-endpoint>
    <logger level="INFO" doc:name="Logger"></logger>
    <jdbc-ee:outbound-endpoint exchange-pattern="request-response"
        connector-ref="Database" doc:name="Database">

        <jdbc-ee:query key="Query"
            value="call GET_HIGH_GENDER('2015-04-16', @HIGHEST_GENDER) "></jdbc-ee:query>

        <db-stored-procedure config-ref="Database">
            <db-parameterized-query>{ call GET_HIGH_GENDER(:JOINING_DATE,
                :HIGHEST_GENDER) }</db-parameterized-query>
            <db-in-param name="JOINING_DATE" value="'2015-04-16'"></db-in-param>
            <db-out-param name="result"></db-out-param>
        </db-stored-procedure>

    </jdbc-ee:outbound-endpoint>

    <data-mapper:transform config-ref="map_to_csv"
        doc:name="Map To CSV"></data-mapper:transform>
    <object-to-string-transformer doc:name="Object to String"></object-to-string-transformer>

    <logger message="#[payload:]" level="INFO" doc:name="Logger"></logger>
</flow>

请帮帮我......谢谢。我收到如下错误消息：

Failed to route event via endpoint:
DefaultOutboundEndpoint{endpointUri=jdbc://Query, connector=EEJdbcConnector
    {
  name=Database

  this=18474a2

}
,  name='endpoint.jdbc.Query', mep=REQUEST_RESPONSE, properties={queryTimeout=-1, queries=merged: {Query=call GET_HIGH_GENDER('2015-04-16', @HIGHEST_GENDER) }}, transactionConfig=Transaction{factory=null, action=INDIFFERENT, timeout=0}, deleteUnacceptedMessages=false, initialState=started, responseTimeout=10000, endpointEncoding=UTF-8, disableTransportTransformer=false}.

你为什么使用

<db-stored-procedure config-ref="Database">
        <db-parameterized-query>{ call GET_HIGH_GENDER(:JOINING_DATE,
            :HIGHEST_GENDER) }</db-parameterized-query>
        <db-in-param name="JOINING_DATE" value="'2015-04-16'"></db-in-param>
        <db-out-param name="result"></db-out-param>
    </db-stored-procedure>

Mule 3.5 Db 组件？如果您使用 Mule 3.4 ，则只需使用

即可

<jdbc-ee:outbound-endpoint exchange-pattern="request-response"  connector-ref="Database" doc:name="Database">
 <jdbc-ee:query key="Query" value="CALL GET_HIGH_GENDER('2015-04-16'; @HIGHEST_GENDER) "></jdbc-ee:query>
</jdbc-ee:outbound-endpoint>

使用调用或 exec 方法调用存储过程。通常通话将用于调用存储过程

感谢@Anirban的帮助。它现在正在工作。正确的是

<jdbc-ee:outbound-endpoint exchange-pattern="request-response" queryKey="Query" connector-ref="Database" doc:name="Database"> 
            <jdbc-ee:query key="Query" value="CALL GET_HIGH_GENDER_STRING(#['2015-04-16';String;in], #[HIGHEST_GENDER;string;out]) "></jdbc-ee:query>  
        </jdbc-ee:outbound-endpoint>
