玩转spring mvc(四)---在spring MVC中整合JPA

关于在Spring MVC中整合JPA是在我的上一篇关于spring mvc基本配置基础上进行的，所以大家先参考一下我的上一篇文章：http://blog.csdn.net/u012116457/article/details/43528111

接下来是需要新添加的一些文件：

jdbc.properties：

jdbc.driverClassName=com.mysql.jdbc.Driver

jdbc.url=jdbc\:mysql\://localhost\:3306/tmos?useUnicode\=true&characterEncoding\=utf-8&autoReconnect\=true

jdbc.user=root

jdbc.password=root

jdbc.dialect=org.hibernate.dialect.MySQL5Dialect

jdbc.show_sql=false

jdbc.format_sql=true

#jdbc.dialect=org.hibernate.dialect.MySQLInnoDBDialect

jdbc.initialPoolSize=2

jdbc.maxPoolSize=200

jdbc.batch_size=20

jdbc.hbm2ddl.auto=update

jdbc.query.substitutions=true 1, false 0, yes ''Y'', no ''N''

jpaConfig.xml:

	<!-- 配置一个Factory -->

    <jpa:repositories base-package="module"

            ref="entityManagerFactory" />

    </bean>

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

</beans>

这样就完成了spring MVC中整合JPA ，在这里大家可以下载本项目，里边包含一些测试代码以及用到的jar包：http://download.csdn.net/detail/u012116457/8426211

这个代码包里的jpaConfig.xml进行了修改，大家可以用这篇文章里贴的jpaConfig.xml的代码替换原来的。
