**二 测试类**

package lee;
    
    
    import org.springframework.context.*;
    import org.springframework.context.support.*;
    
    
    import org.crazyit.app.service.*;
    
    public class SpringTest
    {
        public static void main(String[] args)
        {
            ApplicationContext ctx =
                    new ClassPathXmlApplicationContext("beans.xml");
        }
    }
