求spring mvc +jpa配置

求spring mvc +jpa配置

[code="java"]

基本配置如下:

<!-- JPA实体管理工厂的配置 -->
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="jpaVendorAdapter" ref="hibernateJpaVendorAdapter"/>
    <property name="packagesToScan" value="com.qihangedu.tms"/>
    <!--待扫描的实体类包，不再需要persistence.xml了-->
    <property name="jpaProperties">
        <props>
            <prop key="hibernate.ejb.naming_strategy">org.hibernate.cfg.ImprovedNamingStrategy</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>

<!--指定实现JPA的适配器-->
<bean id="hibernateJpaVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
    <property name="databasePlatform" value="org.hibernate.dialect.MySQL5Dialect"/>
</bean>

<!-- Jpa 事务配置 -->
<bean id="jpaTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
<tx:annotation-driven transaction-manager="jpaTransactionManager"/>

<!-- Spring Data Jpa配置 -->
<jpa:repositories base-package="com.qihangedu.tms"
                  transaction-manager-ref="jpaTransactionManager"
                  entity-manager-factory-ref="entityManagerFactory"/>

[/code]

但是配置你学不到东西 只有通过例子来 知道它为什么要这样配置 这种配置适合哪需求 开发是根据需求来定 用哪种语言来开发
1. 这个是基于注解的SpringMVC整合JPA
