我有一个从CompositeConnectionListener扩展的类，我有一个像这样定义的bean：
@Bean
public CompositeConnectionListener connectionListener(){
return new MyCompositeConnectionListener();
}
public class MyCompositeConnectionListener extends CompositeConnectionListener
{
@Override
public void onClose(Connection conn)
{
.....
@Override
public void onCreate(Connection arg0)
{
.....
}
如果我关闭连接（例如从rabbitmq管理），bean正常工作（我可以检测onClose和onCreate方法）。但是，如果我再次这样做（我再次关闭连接），onclose方法不起作用，只有onCreate方法。我试图弄清楚会发生什么，但现在却不知道为什么。
由于
我使用此类只是为了在连接断开时看到错误消息。在onClose和onCreage方法中，我没什么特别有意思的：
@Override
public void onClose(Connection conn)
{
System.err.println("-------------- onClose(Connection conn) --------------");
super.onClose(conn);
}
@Override
public void onCreate(Connection arg0)
{
try {
System.err.println("-------------- onCreate(Connection arg0) --------------");
super.onCreate(arg0);
}
catch(Exception ex)
{
log.error("Error.", ex);
}
}
这是我的日志：
