各位早上好，

我有一个大问题要在 Mule ESB 中运行。我正在尝试将 CSV 文件映射到 oracle 数据库的表中。为此，我创建了一个带有 Oracle 数据源的 JDBC 连接器，并且连接测试有效。但是，如果我运行 The Job，则会出现错误消息。

[Error Message]

我是否必须将驱动程序“ojdbc7.jar”放在特定目录中？

看起来你已经配置oracle.jdbc.OracleDriver而不是oracle.jdbc.driver.OracleDriver 你可以配置以下示例：-

<spring:beans> 
<spring:bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"    destroy-method="close"> 
        <spring:property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/> 
        <spring:property name="url" value="jdbc:oracle:thin:@192.168.28.129:1521:xe"/> 
        <spring:property name="username" value="yourUserName"/> 
        <spring:property name="password" value="yourPassword"/> 
        <spring:property name="removeAbandoned" value="true"/> 
        <spring:property name="initialSize" value="10"/> 
        <spring:property name="maxActive" value="50"/> 
        </spring:bean> 
</spring:beans>

<db:generic-config name="Database_Configuration" dataSource-ref="dataSource" doc:name="Generic Database Configuration" />

 <flow name="mainFlow">
     <http:listener config-ref="httpListenerConfig" path="/*" doc:name="HTTP" allowedMethods="GET"/> 
///////////////////////////////////////

Your Code
////////////////////////////////////
 <db:select config-ref="Database_Configuration" doc:name="Database">
    <db:parameterized-query><![CDATA[select * from yourtableName]]></db:parameterized-query>
</db:select>
</flow>

您需要根据您的 ip、用户名、密码等进行配置和更改

在类路径中添加 commons-dbcp-1.2.2.jar 或其他版本和 ojdbc6.jar 作为依赖项
