报错：Exception in thread "main" java.lang.ClassCastException: $Proxy0 cannot be cast to com.wr.domain.User
度娘了，说解决方法有两种 1、给service类添加一个接口iService，让service类实现它，则创建代理类时使用JDK动态代理就不会出现问题 2、设置beanNameAutoProxyCreator的proxyTargetClass属性为true，意思是强制使用CGLIB代理，前提是你已经将CGLIB包加入到项目中
第一种方法我已经做了，但是第二种方法我不会怎么弄。
贴上代码，大神帮忙啊，急急！！！

userServiceImpl.addUser(u);
