Caused by: org.springframework.beans.TypeMismatchException: Failed to convert property value of type [java.lang.String] to required type [javax.sql.DataSource] for property 'dataSource'; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [java.lang.String] to required type [javax.sql.DataSource] for property 'dataSource': no matching editors or conversion strategy found
说是这个原因：
Failed to convert property value of type [java.lang.String] to required type [javax.sql.DataSource] for property 'dataSource'
可是我的配置dataSource 没有存在错呢：

希望各位高手能给初学者点鼓励和解决方案：
为什么配置这个就不行啊
value="classpath:META-INF/persistence.xml" />
我已经郁闷了几天了，看了下源代码还是没找到解决办法。飙泪呼唤各位高手。
