Spring4 整合 Hibernate4

1. Spring 整合 Hibernate 整合什么 ?

1). 由 IOC 容器来管理 Hibernate 的 SessionFactory

2). 让 Hibernate 使用上 Spring 的声明式事务

2. 整合步骤:

1). 加入 hibernate

(1). jar 包(所有required 路径下的包)

 

再导入 MySQL 数据库驱动的包 和 c3p0 数据连接池的包

(2). 添加 hibernate 的配置文件:hibernate.cfg.xml（也可以不维护该配置文件，而是在 spring 的配置文件中的 SessionFactory 实例中配置）

<session-factory>

   

   

   

    <property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialectproperty>

    <property name="hibernate.show_sql">trueproperty>

    <property name="hibernate.format_sql">trueproperty>

    <property name="hibernate.hbm2ddl.auto">updateproperty>

   

   

   

    session-factory>

(3). 编写了持久化类对应的 .hbm.xml 文件。

2). 加入 Spring

(1). jar 包

(2). 加入 Spring 的配置文件
