IUserOperation.java：packagecom.yihaomen.mybatis.inter;importjava.util.List;importcom.yihaomen.mybatis.model.Article;importcom.yihaomen.mybatis.model.User;publicinterfaceIUserOperation{publicUserselectUserByID(intid);publicList<User>selectUsers(StringuserName);publicvoidaddUser(Useruser);publicvoidupdateUser(Useruser);publicvoiddeleteUser(intid);publicList<Article>getUserArticles(intid);publicList<Article>getUserArticles_2(intid);}
以上这些方法都是在User.xml中配置实现的本人新手，还望有大神指教
解决方案
解决方案二：
com.yihaomen.mybatis.inter.IUserOperation是不是不在classpath路径里？
解决方案三：
