WEB项目启动加载的实现方式整理
方法一:
实现org.springframework.beans.factory.config.BeanPostProcessor接口:
[java]
public class InstantiationTracingBeanPostProcessor implements BeanPostProcessor {
public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
return bean;
}
public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
return bean;
}
}
在spring配置文件中添加:
[html]
<bean class="***.***.InstantiationTracingBeanPostProcessor"/>
方法二:
实现org.springframework.beans.factory.InitializingBean接口:
[java]
public class SysInitBean implements InitializingBean, ServletContextAware {
public void afterPropertiesSet() throws Exception {
}
@Override
public void setServletContext(ServletContext servletContext) {
}
}
在spring配置文件中添加:
[html
<bean class="***.***.SysInitBean"/>
方法三:
实现javax.servlet.ServletContextListener:
[java]
public class RedisInitListener implements ServletContextListener {
@Override
public void contextDestroyed(ServletContextEvent sce) {
}
@Override
public void contextInitialized(ServletContextEvent sce) {
//WebApplicationContext wa = WebApplicationContextUtils.getWebApplicationContext(sce.getServletContext());
ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
}
}
在web.xml中添加listener:
[html]
<listener>
<listener-class>***.***.RedisInitListener</listener-class>
</listener>
