创建listener实现ServletContext接口
public class SpringServletContextListener implements ServletContextListener { // Public constructor is required by servlet spec public SpringServletContextListener() { } // ------------------------------------------------------- // ServletContextListener implementation // ------------------------------------------------------- public void contextInitialized(ServletContextEvent sce) { // 1获取spring配置文件的名称 ServletContext servletContext = sce.getServletContext(); String config = servletContext.getInitParameter("ConfigLocation"); //1.创建IOC容器 ApplicationContext ctx = new ClassPathXmlApplicationContext(config); // 2.将IOC容器放入servletContext一个属性中 } public void contextDestroyed(ServletContextEvent sce) { /* This method is invoked when the Servlet Context (the Web application) is undeployed or Application Server shuts down. */ } }
在web.xml文件中配置listener和<context-param>属性
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <!--配置spring配置文件的名称和位置--> <context-param> <param-name>ConfigLocation</param-name> <param-value>applicationContext.xml</param-value> </context-param> <!--启动IOC容器的servletContextListener--> <listener> <listener-class>com.marry.spring.struts2.listeners.SpringServletContextListener</listener-class> </listener> </web-app>
