1、环境
a. jar包
(mybatis+spring mvc运行包+两者整合包mybatis-spring.jar)
b.工程目录
c. 配置文件
mybatis:SqlMapConfig.xml、mapper.xml等
spring mvc: applicationContext.xml
a) applicationContext.xml
<beans xmlns="http://www.springframework.org/schema/beans"

<!-- 加载配置文件 db.properties -->
<context:property-placeholder location="classpath:db.properties" />
<!-- 使用dbcp数据源 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${jdbc.driver}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="maxActive" value="15" />
<property name="maxIdle" value="3" />
</bean>
<!-- sqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 加载mybatis的配置文件 -->
<property name="configLocation" value="mybatis/SqlMapConfig.xml" />
<!-- 数据源 -->
<property name="dataSource" ref="dataSource" />
</bean>
</beans>
理解
2.原始dao开发
a. dao
b.user.xml
c.SqlMapConfig.xml
d.impl(要继承SqlSessionDaoSupport)
纯mybatis的话,这里是注入一个SqlSession来操作的。整合spring后通过SqlSessionDaoSupport的getSqlSession来操作。
e.applicationContext配置bean
f.测试程序
3.mapper代理
a.UserMapper.java
b.UserMapper.xml
c.SqlMapConfig.xml(不需要)
d.applicationContext配置
方法一,单个
方法二,批量
