spring-data-jpa中save不觸發數據庫insert語句的問題

最近學習spring mvc，用到jpa簡化DAO層代碼，發現save死活不觸發SQL語句，找了很久才解決這個問題，實在是坑。、

<!-- 關鍵是這個bean，必定要設置正確才行 -->
<bean id="transactionManager">

 

二話不說了，直接貼配置文件：

    </jdbc:initialize-database>
    
    <!-- 事務 就是這裏有問題啦 --> 
    <!--  Since you're using JPA, 
        the transaction manager should be a JpaTransactionManager, 
        not a DataSourceTransactionManager.  -->
    <!-- <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>   --> 
    <!-- fuck off !!! -->
    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <tx:annotation-driven transaction-manager="transactionManager"
        proxy-target-class="true" />
</beans>

stackoverflow上找到了緣由，就是這個JPA，有一個專用的事務管理器，org.springframework.jdbc.datasource.DataSourceTransactionManager，若是用DataSourceTransactionManager就不行了。終於解決了，下次研究一下二者有什麼不一樣。
