我正在尝试在以下环境中部署应用程序.

• JPA 2.0
• 春天3.2.2
• MySQL 5.6.11

到目前为止我在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"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:aop="http://www.springframework.org/schema/aop"

        <!--<property name="jpaVendorAdapter">

                <property name="generateDdl" value="true"/>
                <property name="databasePlatform" value="org.hibernate.dialect.HSQLDialect"/>
            </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>
