http://pan.baidu.com/s/1hrARhbu这是我项目的地址。。用IDEA写的。。也是第一次用这个程序。。求大佬帮忙看看。。

Error creating bean with name 'baseService': I 是这个bean的注入的相关问题吧，给你看一个看链接， http://blog.csdn.net/qq598535550/article/details/51169688

[爱睡觉的阿狸]

expected single matching bean but found 2: baseDaoImpl,userDaoImpl baseDaoImpl,userDaoImpl都实现了IBaseDao，所以当你注入IBaseDao类型的属性的时候，系统不知道该注入哪个，建议改为注入具体的实现类。

谢谢大佬 我看了一下他的是抽象类的错误。 他举出的四种错误。。第一种应该没问题、、第二种我刚加了。。还是报一样的错。。至于后面的配置和死循环。。我也刚学配置不太懂。。

诶版主大大~ 我看了一下UserDaoImpl是实现IUserDao。我用这个项目的主要目的是能支持数据库。我昨天已经成功的配置了一个可以运行的SpringMVC项目，。可惜他没数据库，然后我在论坛里找到这个用一堆base啥的~想到时候添加新的数据表可能会轻松很多。。以前hibernate直接下一步下一步就生成好多类了。。都不用自己写。。不知道这个框架怎么弄。。

IUserDao是不是又继承了IBaseDao？

那就是要一个个写嘛？不能继承一个基础类咯。。 那我就换一个项目把。这项目有两种。。一种是有基础类的 一种是不同的实体写不同的类的。。
