1.類上加註解@Component
2.實現InitializingBean介面，重新afterPropertiesSet方法
如下案例SpringBoot專案啟動netty客戶端

@Component
public class BusiClient implements InitializingBean {
    @Override
    public void afterPropertiesSet() throws Exception {
        NettyClient nettyClient = new NettyClient();
        new
 
 Thread(nettyClient).start();
        while(!nettyClient.isConnected()){
            synchronized (nettyClient){
                nettyClient.wait();
            }
        }
        System.out.println("網路通訊已準備好，可以進行業務操作了........");
        Scanner scanner = new Scanner(System.in);
        while
 
 (true) {
            String msg = scanner.next();
            if (msg == null) {
                continue;
            } else if ("q".equals(msg.toLowerCase())) {
                nettyClient.close();
                while(nettyClient.isConnected()){
                    synchronized (nettyClient)
 
{
                        nettyClient.wait();
                    }
                }
                scanner.close();
                System.exit(1);
            } else {
                nettyClient.send(msg);
            }
        }
    }
}
