异常：org.apache.ibatis.exceptions.PersistenceException:

在学习mybatis的延迟加载这部分的内容的时候，配置好测试时，报如下错误：

org.apache.ibatis.exceptions.PersistenceException:

解决办法：

其实同一个异常出现的原因有多个，我百度了一下，看到这篇文章，讲的是因为没有配置好别名，或者没加namespace

http://blog.csdn.net/jyxmust/article/details/55096762

而我检查一下自己并没有那个的错误，再仔细看看，发现

Cause: org.apache.ibatis.builder.BuilderException: The setting LazyLoadingEnabled is not known. Make sure you spelled it correctly (case sensitive).
说明我LazyLoadingEnabled写错了，可是看对应视频里没错啊，

没办法找了视频里的源码黏贴进去，没错！
后来发现，坑爹的，

LazyLoadingEnabled首字母是小写！！！

以后还是要小心点，代码太险恶了！

结束和声明

以上纯属个人观点和体会
希望这篇文章能对你有所帮助！
欢迎大家来一起讨论分享干货，或者批评指正！
更加热切盼望各路大神前辈给些指导和建议！

以后会不定期更新心得和总结，包括学习过程中各种异常和解决办法等等。再见！
