Mule MySQL连接器

我正在尝试使用本教程将Mule连接到MySQL数据库（在Mule中非常新）：

我一直往下走到步骤6（测试列表项）。如果转到指定的URL，则会出现以下错误：

Failed to route event via endpoint: DefaultOutboundEndpoint{endpointUri=jdbc://selectAll, connector=EEJdbcConnector
{
  name=Database
  lifecycle=start
  this=5b3808ad
  numberOfConcurrentTransactedReceivers=4
  createMultipleTransactedReceivers=false
  connected=true
  supportedProtocols=[jdbc]
  serviceOverrides=<none>
}
,  name='endpoint.jdbc.selectAll', mep=REQUEST_RESPONSE, properties={queryTimeout=-1}, transactionConfig=Transaction{factory=null, action=INDIFFERENT, timeout=0}, deleteUnacceptedMessages=false, initialState=started, responseTimeout=10000, endpointEncoding=UTF-8, disableTransportTransformer=false}. Message payload is of type: String

未能通过端点路由事件：DefaultOutboundEndpoint{endpointUri=jdbc://selectAll，connector=EEJdbcConnector
{
名称=数据库
生命周期=开始
这个=5b3808ad
ConcurrentTransacticedReceiver的数量=4
CreateMultipleTransactedReceiver=false
已连接=真
supportedProtocols=[jdbc]
服务覆盖=
}
，name='endpoint.jdbc.selectAll'，mep=REQUEST\u RESPONSE，properties={queryTimeout=-1}，transactionConfig=Transaction{factory=null，action=interference，timeout=0}，deleteUnceptedMessages=false，initialState=started，responseTimeout=10000，endpointEncoding=UTF-8，disableTransportTransformer=false}。消息负载的类型为：String

我已经找了很长时间了，但我找不到解决办法。 也许你们能帮我一下

这是我的XML：

    </flow>
</mule>

尝试了最新的MySQL连接器（MySQL-Connector-java-5.1.29-bin），以及教程中提到的1。两个都不起作用

有人知道如何解决这个问题吗

谢谢！

错误信息显示

jdbc://selectAll

，看起来您的数据源url不正确。如果查看MySql连接器教程示例，url的样式应该是

jdbc:mysql://localhost:3306/mulesoft_db

此配置适合我

<db:generic-config name="Generic_Database_Configuration" url="jdbc:postgresql://localhost/isnews?password=postgres&amp;user=goncalodias" driverClassName="org.postgresql.Driver" doc:name="Generic Database Configuration">
</db:generic-config>
<db:mysql-config name="MySQL_Configuration" host="localhost" port="3306" user="root" password="passwd" database="IS" doc:name="MySQL Configuration"/>

谢谢！查看SQL数据源。来源是好的，但用户没有工作。我已经为Mule创建了一个用户，主机为Any（在phpMyAdmin中）。我将主机更改为localhost，并且工作正常。请查看页面roytuts.com/mule-jdbc-insert-example/
