由于需要做一定定时轮询程序,自己写了一个Servlet小程序,在Servlet里面的Init函数中做一个Timer,定时执行程序。
代码如下:
public class MailStartup extends HttpServlet {
public static void main(String[] args) {
try { new MailStartup().init(); } catch (ServletException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } }public void init() throws ServletException {
super.init(); try{ System.out.println("待发送服务 SendMailOperator start time at......................."); int length= Integer.parseInt(ServerConfig.getProperty("SendMailOperator.timer","30")); Timer operatorTimer = new Timer(); SendMailOperator operator = new SendMailOperator(); operatorTimer.schedule(operator, 0, length); }catch(Exception ex){ ex.printStackTrace(); }}}
还需要在web.xml做一些配置,就可以了,配置如下:
<servlet>
<servlet-name>MailSend</servlet-name><servlet-class>cn.efreight.email.MailStartup</servlet-class><load-on-startup>2</load-on-startup></servlet><servlet-mapping><servlet-name>MailSend</servlet-name><url-pattern>/mail/*</url-pattern></servlet-mapping>重启tomcat即可。
