Tomcat监听器
如果需要在tomcat启动的时候加载一些服务,可以采用监听器的方式,监听器要实现ServletContextListener类.public class XXXListener implements ServletContextListener {
/**
*
*/
private static final long serialVersionUID = 1L;
public void contextDestroyed(ServletContextEvent arg0) {
// TODO Auto-generated method stub
}
public void contextInitialized(ServletContextEvent arg0) {
// TODO Auto-generated method stub
arg0.getServletContext().setAttribute("XXX",xxx);//保存为Application域
}
}
另外,需要在web.xml里配置该监听器如下:
<listener>
<listener-class>packagePath.XXXListener</listener-class>
</listener>
