Java 如果具有@Repository或PersistenceExceptionTranslationPostProcessor bean，则创建bean时出错

我是spring的新手，我正在使用Gary Mak的《spring食谱：问题解决方法》一书学习spring

无论如何，我在使用时遇到了这个问题 PersistenceExceptionTranslationPostProcessor

这是我的applicationContext.xml

    <?xml version="1.0" encoding="UTF-8"?>

但是当我在EmployeeDaoImpl上注释掉@Repository注释或者注释掉PersistenceExceptionTranslationPostProcessor bean声明时，applicationContext会正确加载

    <!-- <bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />  -->

or

//@Repository
public class EmployeeDaoImpl implements EmployeeDao{
       ...........
}

或
//@存储库
公共类EmployeeDaoImpl实现EmployeeDao{
...........
}

---

我想知道为什么会发生这种情况。有人能给我解释一下吗。

HibWorker的类型。employeeDaoImpl是

EmployeeDaoI
    <!-- <bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />  -->

or

//@Repository
public class EmployeeDaoImpl implements EmployeeDao{
       ...........
}
