SSHM（Spring，SpringMVC，Hibernate，Mybatis）基于xml文件和注解（@Annotation）

SSHM简单整合

工具与环境

IDEA开发环境

Maven自动构建工具

JDK1.8

目录结构

注意

在Spring配置文件中配置事务管理器时，

若持久层只用了Mybatis，则事务管理器可使用

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>

但若持久层同时整合了Hibernate和Mybatis，则事务管理器则需如下配置

<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<!--Hibernate的SessionFactory-->
<property name="sessionFactory" ref="sessionFactory" />
<property name="dataSource" ref="dataSource" />
</bean>
