本文档详细介绍了如何在Spring应用中整合JPA，包括所需的jar包、数据源配置、entityManagerFactory设置、事务管理器配置，以及相关属性的详细说明，帮助开发者快速搭建Spring JPA环境。

jpa 整合spring

一、导入jar包

antlr-2.7.7.jar
dom4j-1.6.1.jar
ehcache-core-2.4.3.jar
hamcrest-core-1.3.jar
hibernate-commons-annotations-4.0.2.Final.jar
hibernate-core-4.2.4.Final.jar
hibernate-ehcache-4.2.4.Final.jar
hibernate-entitymanager-4.2.4.Final.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
javassist-3.15.0-GA.jar
jboss-logging-3.1.0.GA.jar
jboss-transaction-api_1.1_spec-1.0.1.Final.jar
junit-4.10.jar
mysql-connector-java-5.1.7-bin.jar
slf4j-api-1.6.1.jar

二、配置spring 配置文件application.xml

1、导入数据源

<bean class="com.mchange.v2.c3p0.ComboPooledDataSource" id="dataSource">
    <property name="jdbcUrl" value="${jdbc.url}"/>
    <property name="user" value="${jdbc.username}"/>
    <property name="password" value="${jdbc.password}"/>
    <property name="driverClass" value="${jdbc.driver}"/>
</bean>

2、配置jpaFactionBean

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

    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/>
    </property>

    <property name="packagesToScan" value="com.kuang"/>

    <!-- <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>-->

    <property name="jpaProperties">
        <props>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">true</prop
            <prop key="hibernate.hbm2ddl.auto">update</prop>
        </props>
    </property>
</bean>

3、配置事务

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

        </property>
    </bean>

    <bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">

    </bean>

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

</beans>
