SpringMVC记录

Spring+SpringMVC+Hibernate整合。

关于Spring配置文件的加载问题
要新建一个ServletContextListener在ServletContext初始化时获取ApplicationContext。

    public void contextInitialized(ServletContextEvent arg0) {
        ServletContext sct = arg0.getServletContext();
        String congif = sct.getInitParameter("contextConfigLocation");
        ApplicationContext act = new ClassPathXmlApplicationContext(congif);
        sct.setAttribute("ApplicationContext", act);

    }

然后在Controller中获取这个ApplicationContext

WebApplicationContext webApplicationContext = ContextLoader.getCurrentWebApplicationContext();
        ServletContext servletContext = webApplicationContext.getServletContext();
        ApplicationContext act = (ApplicationContext) servletContext.getAttribute("ApplicationContext");
        OperationDb operationDb = (OperationDb) act.getBean("operationDb");
