org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaMappingContext': Invocation of init method failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined 

搭建的環境折騰了很久，以后遇到這種類似問題，原來是這個原因，已經哭暈

結果對比：

LocalContainerEntityManagerFactoryBean spring


環境搭建的參考文章：http://my.oschina.net/gaussik/blog/513444,總是報錯，解決這個問題，搜了無數的帖子，通過對比原來是這個原因。
