注入持久依赖失败；嵌套异常是 org.springframework.beans.factory.BeanCreationException

Question

我创建了一个 spring、hibernate 项目，它给出了以下异常

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'baseDaoImpl': Injection of persistence dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: No Persistence provider for EntityManager named testJPA

我的applicationContext.xml（下：src/main/recources）如下

    <tx:annotation-driven transaction-manager="transactionManager" />

</beans>

和persistance.xml（下：src/main/resources/META-INF）如下

<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence

   <persistence-unit name="BookJpaPersistanceUnit" transaction-type="RESOURCE_LOCAL">
     <provider>org.hibernate.ejb.HibernatePersistance</provider>

     <properties>
       <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
       <property name="hibernate.hbm2ddl.auto" value="create"/>
       <property name="hibernate.show_sql" value="true"/>
       <property name="hibernate.format_sql" value="true"/>
       <property name="hibernate.use_sql_comments" value="true"/>
     </properties>
   </persistence-unit>

</persistence>

我该如何解决这个问题？？

这是 DaoImpl 类

@Repository
@Transactional
public class BaseDaoImpl implements BaseDao {

    @PersistenceContext
    EntityManager em;

    public void persist(Object obj) {

        em.persist(obj);

    }

    public <T> List<T> getAll(Class clazz) {

        TypedQuery<T> query= em.createQuery(" from "+ clazz.getName(), clazz);
        return query.getResultList();
    }

}

请将 src/main/resources/META-INF/persistance.xml 重命名为 src/main/resources/META-INF/persistence.xml 。
