微信接口開發緩存全局token，ticket

在服務啓動監聽器裏定時請求，緩存到靜態的變量中，time=7000秒

public class StartupListener extends ContextLoaderListener implements
		ServletContextListener {

	int time = 7000;
	@Override
	public void contextInitialized(ServletContextEvent event) {
		super.contextInitialized(event);
		new Thread(new Runnable() {
			public void run() {
				while(true){
					Param.TOKEN = WeiXinUtil.getToken();
					Param.TICKET = WeiXinUtil.getConfig();
					System.out.println("token:"+Param.TOKEN.getAccess_token()+" , ticken:"+Param.TICKET);
					try {
						Thread.sleep(time*1000);
					} catch (Exception e) {
						e.printStackTrace();
					}
				}
			}
		}).start();
	}
	
}
