您可以创建一个单独的线程来监控数据库连接。在启动服务器时调用该线程。如果数据库连接失败意味着发送来自该威胁的邮件。

例子 ：

        boolean isDBConnected,isServerConnected;
        while(true){                
            isDBConnected=checkDBConnection();
            isServerConnected=checkServerStatus();
            if(isDBConnected && isServerConnected){
                Thread.sleep(100);
            }else{
                sendMail();
                break;
            }
        }
