分布式之_多线程之指定线程运行服务器

appliction-frame.xml配置

后台主线程，用于启动其他线程,这里使用Spring的InitializingBean的afterPropertiesSet()方法来初始化后台主线程，即web容器启动，取初始启动后台主线程

// 后台主线程，用于启动其他线程
@Log4j
public class AppThreadStart implements InitializingBean
{
	// 可在多台服务器上同时运行的后台线程
	@Setter
	private List multipleThreadObjects;

	// 只能在单台服务器上运行的后台线程
	@Setter
	private List singleThreadObjects;

	// 只能在单台服务器上运行的后台线程，在IP地址为这个的服务器上运行
	@Setter
	private String singleIpAddress;

	public void afterPropertiesSet() throws Exception
	{
		if (CollectionUtils.isNotEmpty(multipleThreadObjects))
		{
			Iterator iterator = multipleThreadObjects.iterator();
			while (iterator.hasNext())

				Object object = iterator.next();
				start(object);

		}

		String localHostAddress = NetworkUtils.localHostAddress();

		StringBuffer message = new StringBuffer();
		message.append("LocalHostAddress: " + localHostAddress);
		message.append(", SingleMachineIpAddress: " + singleIpAddress);
		log.info(message.toString());

		if (!StringUtils.equals(localHostAddress, singleIpAddress))
			return;

	}

	private void start(Object object)
	{
