atomikos配置多个数据源JTA管理事务

配置两个dataSource

<bean id="dataSource" class="com.atomikos.jdbc.AtomikosDataSourceBean">
        <property name="uniqueResourceName"><value>yw</value></property>
        <property name="xaDataSourceClassName" value="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource"/>
        <property name="xaProperties">
            <props>
                <prop key="URL">${jdbc.url}</prop>
                <prop key="user">${jdbc.username}</prop>
                <prop key="password">${jdbc.password}</prop>
            </props>
        </property>
        <property name="poolSize"><value>1</value></property>
        <property name="minPoolSize" value="2" />
        <property name="maxPoolSize" value="10" />
    </bean>

    <!-- 测试 -->
    <bean id="dataSource2" class="com.atomikos.jdbc.AtomikosDataSourceBean">
        <property name="uniqueResourceName"><value>ds2</value></property>
        <property name="xaDataSourceClassName" value="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource"/>
        <property name="xaProperties">
            <props>
                <prop key="URL">${jdbc.url2}</prop>
                <prop key="user">${jdbc.username2}</prop>
                <prop key="password">${jdbc.password2}</prop>
            </props>
        </property>
        <property name="poolSize"><value>1</value></property>
        <property name="minPoolSize" value="2" />
        <property name="maxPoolSize" value="10" />
    </bean>

jdbctemplate配置

    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource">
            <ref local="dataSource" />
        </property>
    </bean>
    <!-- 测试数据源 -->
    <bean id="jdbcTemplate2" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource">
            <ref local="dataSource2" />
        </property>
    </bean>
    <bean id="baseDao" class="com.szy.base.BaseDao">
        <property name="jdbcTemplate">  <ref bean="jdbcTemplate" />
        </property>
    </bean>

第二个数据源可以用spring注解注入。

public class BaseDao2 {
    @Resource(name = "jdbcTemplate2")
     protected JdbcTemplate jdbcTemplate2=null;
     private int total=0;

    public void setTotal(int total) {
        this.total = total;
    }

}

配置事务管理

        <!-- 开始配置JTA事务  -->
    <bean id="atomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager" init-method="init" destroy-method="close">
        <property name="forceShutdown"><value>true</value></property>
    </bean>

    <bean id="atomikosUserTransaction" class="com.atomikos.icatch.jta.UserTransactionImp">
        <property name="transactionTimeout"><value>300</value></property>
    </bean>

    <bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
        <property name="transactionManager">
            <ref local="atomikosTransactionManager"/>
        </property>
        <property name="userTransaction">
            <ref local="atomikosUserTransaction"/>
        </property>
    </bean>

    <!-- 使用annotation定义事务 -->
    <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true" />

这样就完成了。
