我正在尝试在以下环境中部署应用程序。

• JPA 2.0
• spring3.2.2
• MySQL 5.6.11

到目前为止，application-context.xml文件中的配置如下。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </bean>
        </property>-->
    </bean>

    <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory"/>
    </bean>

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

    <bean id="testDAOService" class="admin.dao.TestDAO"/>
</beans>

在上面的xml文件中的注释行取消注释之前，此方法可以正常工作。当这些行取消注释时，我将收到以下异常。

我试图添加hibernate-entity- manger-4.2.0.jar到类路径，但这导致了另一个异常java.lang.ClassNotFoundException: org.hibernate.HibernateException。

那么，正是在这里需要哪些jar文件？它是否取决于我在此应用程序中未使用的Hibernate框架？

该persistence.xml文件如下所示。

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" 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 http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
  <persistence-unit name="WebAppPU" transaction-type="RESOURCE_LOCAL">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <class>model.Test</class>

    <properties>
      <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/social_networking?zeroDateTimeBehavior=convertToNull"/>

      <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
      <property name="javax.persistence.jdbc.user" value="root"/>
    </properties>
  </persistence-unit>
</persistence>

更新：

快速回复：（ 因为以下答案并未直接解决导致异常的原因）

出现所述异常的原因是（很可能是）我在使用MySQL
5.x时，如给定XML文件中databasePlatform那样配置错误org.hibernate.dialect.HSQLDialect。

实际上，它应该是org.hibernate.dialect.MySQLDialect（或受版本限制/特定于版本的-
org.hibernate.dialect.MySQL5Dialect）。

免责声明： 我不记得确切的异常原因超过一年后，但是很可能是（99.99％）这种错误配置是造成这种情况的罪魁祸首。
