Question

当我向mule服务发送请求时，我想将一些信息保存到数据库。对于这个问题：我在xml文件中写了下面的配置：

    <mule xmlns:vm="http://www.mulesoft.org/schema/mule/vm" xmlns:http="http://www.mulesoft.org/schema/mule/http"

</flow>

和IpClient类：

public class IpClient  implements Callable,ModelNotificationListener<ModelNotification>  {


@Override
public void onNotification(ModelNotification notification) {
    // TODO Auto-generated method stub
    System.out.println("Notification order event: " + notification.getActionName() );

    if(notification.getAction() == ModelNotification.MODEL_DISPOSED || notification.getAction() == ModelNotification.MODEL_STOPPED){

        DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
        Date date = new Date();

        ConnectDB c = new ConnectDB("localhost:3306", "accounting", "root", "");

        String sql = " INSERT INTO weather (ip, date, CurrentState) VALUES (?,?,?) ";

        PreparedStatement ps = null;
        try {
            ps = c.getConnnection().prepareStatement(sql);
            ps.setString(1, "127.0.0.1");
            ps.setString(2, dateFormat.format(date).toString());                
            ps.setString(3, notification.getActionName());                                 
            ps.executeUpdate();
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } finally {
            c.close();
        }           

    }
}


@Override
public Object onCall(MuleEventContext eventContext) throws Exception {


    MuleMessage msg = eventContext.getMessage();    

    String remClient = msg.getProperty("remoteClientAddress", PropertyScope.INVOCATION);


    DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
    Date date = new Date();

    ConnectDB c = new ConnectDB("localhost:3306", "accounting", "root", "");

    String sql = " INSERT INTO weather (ip, date, CurrentState) VALUES (?,?,?) ";

    PreparedStatement ps = c.getConnnection().prepareStatement(sql);

    ps.setString(1, remClient);

    ps.setString(2, dateFormat.format(date).toString());

    ps.setString(3, msg.getMuleContext().getLifecycleManager().getCurrentPhase());

    ps.executeUpdate();

    c.close();

    return msg.getPayload();

}

}

如果我开始运行服务，这个程序就能正常工作。例如我的服务突然之前运行（例如我的wsdl（http://wsf.cdyne.com/WeatherWS/Weather.asmx?wsdl不起作用））。我的日志程序保存所有记录处于开始状态，并且在解密后它的工作方式类似。如果我停止我的服务并再次运行它，它可以正常工作，并以压缩模式保存所有记录。我不知道如何更改我在运行时正确保存的程序。

（病名）Initializer bean未在配置中的任何位置用作<component>，因此无法调用其onCall方法。

如果你打算用：

<notification event="COMPONENT-MESSAGE"/>

是要为每个组件调用调用Initializer，然后必须使其实现ComponentMessageNotificationListener（就像你使它实现ModelNotificationListener）。

为什么不改变mule运行时的生命周期状态？
