Spring+Ibatis 与 Spring+Hibernate的区别在于Ibatis和Hibernate的配置不同，下面来看下Ibatis的配置

 

<jee:jndi-lookup id="ds0" jndi-name="jdbc/ds0"/>
<jee:jndi-lookup id="ds1" jndi-name="jdbc/ds1"/>
<jee:jndi-lookup id="ds2" jndi-name="jdbc/ds2"/>
<bean id="dataSource" class="com.xxx.xxx.util.DynamicDataSource">
<property name="targetDataSources">
<map key-type="java.lang.String">
<entry key="1" value-ref="ds1"/>
<entry key="2" value-ref="ds2"/>
</map>
</property>
<property name="defaultTargetDataSource" ref="ds0"/>
</bean>
<!-- SqlMap setup for iBATIS Database Layer -->
<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="configLocation" value="classpath:com/xxx/xxx/dao/sqlmap/sql-map-config.xml"/>
</bean>


 

sql-map-config.xml 如下：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE sqlMapConfig PUBLIC "-////DTD SQL Map Config 2.0//EN"   
>
<sqlMapConfig>
<sqlMap resource="com/xxx/xxx/dao/sqlmap/Object.xml"/>
</sqlMapConfig>


 

核心是DynamicDataSource 与 上下文DynamicDataSourceHolder为一线程安全的ThreadLocal，都和上一篇文章的中对应的类相同。
