原因

同时引入了persistence-api-1.0-sources.jar和hibernate-jpa-2.1-api-1.0.0.Final.jar包冲突。

解决方法

在引入hibernate-core时已经包含了javax.persistence.OneToOne相关jar包内容，移出persistence-api包的引入即可。

<dependency>      <groupId>javax.persistence</groupId>      <artifactId>persistence-api</artifactId>      <version>1.0</version></dependency>
