ApplicationContext ac=new ClassPathXmlApplicationContext("beans.xml");

是抛异常
这是异常信息：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

	at org.springframework.context.support.AbstractApplicationContext.<init>(AbstractApplicationContext.java:145)

	at org.springframework.context.support.AbstractRefreshableApplicationContext.<init>(AbstractRefreshableApplicationContext.java:84)

	at org.springframework.context.support.AbstractRefreshableConfigApplicationContext.<init>(AbstractRefreshableConfigApplicationContext.java:59)

	at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:83)

	at com.springmodel.A.main(A.java:14)

这是beans.xml中的信息
