web项目中通过spring获得ApplicationContext

方法一、

    @Override
    public void sessionDestroyed(HttpSessionEvent event) {

        ServletContext context = event.getSession().getServletContext();
        ApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(context);
        LoginTempService loginTempService = (loginTempService)ctx.getBean("loginTempService");
    }

方法二、如果在 web工程里，有几个方法,我觉得这个方法最方便。建个类，实现spring的ApplicationContextAware 接口，即 

public class SpringContextTool implements ApplicationContextAware {
    private static ApplicationContext context;
    public void setApplicationContext(ApplicationContext acx) {
     context = acx;
    }

    public static ApplicationContext getApplicationContext() {
        return context;
    }
 }
