尝试此配置。你的persistence.xml中有错误请分享错误。

<bean id="hibernateJpaVendorAdapter"
    class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
<bean id="hibernateJpaDialect" class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan" value="com.test.entity" />
    <property name="jpaDialect" ref="hibernateJpaDialect" />
