基本都是抄的代码，想运行试试结果发现报错
Cannot find class [spring.spring.User] for bean with name 'user' defined in class path resource [beans.xml];
应该是路径问题但是改了好多种都不对啊(╯‵□′)╯︵┻━┻，求教
学得不精呀。嘻嘻。
ClassPathXmlApplicationContext，如果要用这个，把你的beans.xml放到你的源代码根目录下。
换句话说，看看你的编译目标目录下（比如classes或target），有没有这个文件产生。
把beans.xml贴出来看看，你的User 类在spring package下,那beans.xml中 user bean 就应该这样配置：
<bean id="userDao" class="spring.UserDao">
<property name="user">
<ref bean="user"/>
</property>
</bean>
<bean id="user" class="spring.User"></bean>
