|
1 2 3 |
WebApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext()); ApplicationContext ac1 = WebApplicationContextUtils.getRequiredWebApplicationContext(request.getSession().getServletContext());//失败时抛出异常 ApplicationContext ac2 = WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext()); //失败时返回null |
B.
