[align=center][b]spring+ibatis配置多数据源[/b][/align]
说明:最近因为项目需要,经过多方努力和救助,终于实现了spring+ibatis的动态数据源切换配置,在此贴出,以供大家参考,同时希望大家多提意见……
下面是详细代码:
1. spring的applicationContext.xml配置文件:
a. 属性文件配置:
<bean id="propertyConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value> classpath:resource/DataSourceConfig.properties
</value>
</property>
</bean>
b. DataSource: C3P0连接池:
【注意:由于存在多数据源,故此步按需要多次配置】
<bean id="dataSource"
class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close">
<property name="driverClass" value="${gpt.driverClassName}" />
<property name="jdbcUrl" value="${gpt.url}" />
<property name="user" value="${gpt.username}" />
<property name="password" value="${gpt.password}" />
<property name="minPoolSize" value="${gpt.minPoolSize}" />
<property name="acquireRetryAttempts"
value="${gpt.acquireRetryAttempts}" />
<property name="acquireIncrement"
value="${gpt.acquireIncrement}" />
<property name="maxIdleTime" value="${gpt.maxIdleTime}" />
<property name="initialPoolSize" value="${gpt.initialPoolSize}" />
<property name="maxPoolSize" value="${gpt.maxPoolSize}" />
<property name="idleConnectionTestPeriod"
value="${gpt.idleConnectionTestPeriod}" />
</bean>
c. spring事务管理配置:
【红色标记处,多个数据源配置多个】
<bean id="autoProxyCreator" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
<property name="beanNames">
<value>*Service</value>
</property>
<property name="interceptorNames">
<list><value>transactionInterceptor1</value> <value>transactionInterceptor2</value> <value>transactionInterceptor3</value>
</list>
</property>
</bean>
<!-- 标记段重复配置,具体看自己需要 start -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="transactionInterceptor1" class="org.springframework.transaction.interceptor.TransactionInterceptor">
<property name="transactionManager" ref="transactionManager" />
<property name="transactionAttributes">
<props>
<prop key="insert*">PROPAGATION_REQUIRED</prop>
<prop key="delete*">PROPAGATION_REQUIRED</prop>
<prop key="update*">PROPAGATION_REQUIRED</prop>
<prop key="do*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
<!-- end -->
d. ibatis sql map 配置:
【同理,有多少个数据源就配置多少遍】
<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:com/sqlmap/sqlmap-config.xml" />
就这样,spring配置文件就准备好了。
</bean>
