基于TCP/IP协议的socket通讯server

思路:

socket必须要随项目启动时启动，所以需用Spring自带的监听器，需要保持长连接，要用死循环，所以必须另外起线程，不能阻碍主线程运行

1.在项目的web.xml中配置listener

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
<listener>
    <listener-class>com.ra.car.utils.MyListener</listener-class>
  </listener>

2.因为是一个独立的线程,所以需要调用的注入类不能通过@resource或@aotowire注入，需要应用上下文获取

3.创建listener监听器类

/**

 */
public class MyListener implements ServletContextListener {

    protected static final Logger logge = LoggerFactory
            .getLogger(MyListener.class);

    @Override
    public void contextInitialized(ServletContextEvent arg0) {
        //必须单独启线程去跑listener
        Mythread myThread = new Mythread();
        //创建一个可缓存线程池，如果线程池长度超过处理需要，可灵活回收空闲线程，若无可回收，则新建线程
//        ExecutorService cachedThreadPool = Executors.newCachedThreadPool();
//        cachedThreadPool.execute(myThread);
        Thread thread = new Thread(myThread);
        thread.start();
        //启动MQTT
//        MQTTSubMsg client = new MQTTSubMsg();
//        client.start();
        RabbitMQCustomer customer=new RabbitMQCustomer();
        Thread threadCustomer = new Thread(customer);
        threadCustomer.start();

        PBWRabbitMQCustomer pbwcustomer=new PBWRabbitMQCustomer();
        Thread pbwT = new Thread(pbwcustomer);
        pbwT.start();
    }

    @Override
    public void contextDestroyed(ServletContextEvent arg0) {
        logge.info("进入ListenerUtil的contextDestroyed方法.........");
    }
