</bean>在數據庫中插入記錄.
spring獲取bean工具類
public class BeanUtil implements ApplicationContextAware{
private static ApplicationContext context;
@Override
public void setApplicationContext(ApplicationContext arg0) throws BeansException {
// TODO Auto-generated method stub
context = arg0;
}
public static Object getBean(String beanName){
return context.getBean(beanName);
}
public static <T> Object getBeanByClass(Class<T> c){
return context.getBean(c);
}
}監聽器用於服務啓動初始化定時任務
public class TaskListener implements ServletContextListener{
private static final Logger logger = LoggerFactory.getActionLog(TaskListener.class);
@Override
public void contextDestroyed(ServletContextEvent arg0) {
// TODO Auto-generated method stub
}
@Override
public void contextInitialized(ServletContextEvent arg0) {
logger.info("TaskListener", "定時任務初始化");
JobManage m = (JobManage) BeanUtil.getBean("jobManage");
try {
m.initTask();
} catch (SchedulerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}TimedTaskService 定時任務服務類就是獲取前端請求對數據庫的操作,需注入JobManage類來對定時任務進行管理最終頁面效果
