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

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，这个程序就可以正常工作。例如，我的服务在突然被处置之前运行（例如我的 wsdl（http://wsf.cdyne.com/WeatherWS/Weather.asmx?wsdl不起作用））。我的日志程序将所有记录保存在启动状态，并且在处理后它的工作方式类似。如果我停止我的服务并再次运行它，它会正常工作并将所有记录保存在处置模式下。我不知道如何更改它在运行时正确保存的程序。
