spring+mybatis+atomikos 实现JTA事务

sping配置多个数据源 不同用户操作不同数据库 http://www.oschina.net/code/snippet_2287006_56769


1：spring3.0之后不再支持jtom[jta]了，第三方开源软件atomikos(http://www.atomikos.com/)来实现．
2：org.springframework.transaction.jta.JotmFactoryBean类，spring-tx-2.5.6.jar中有此类，spring-tx-3.0.0.RELEASE.jar之后没有此类。
3：atomikos事务控制框架，其中看到有3种数据源，分别是，SimpleDataSourceBean,AtomikosDataSourceBean,AtomikosNonXADataSourceBean。
   a:SimpleDataSourceBean: 这个是最简单地数据源配置,需要配置XA驱动。
   b:AtomikosDataSourceBean:  分布式数据源,Atomikos实现的数据源，需要配置XA驱动，推荐此配置，可以配置连接池的信息。
   c:AtomikosNonXADataSourceBean: 非分布式数据源,该数据源配置需要普通JDBC的驱动，可以配置连接池：
4：Atomikos支持XA(全局事务)和NON-XA(非全局事务)，NON-XA[nonxadatasource]效率高于XA.XA事务往往是包括多个数据源的全局事务，非XA是单个数据源的.
5：XA连接是一个JTA事务中的参与者。XA连接不支持JDBC的自动提交特性。也就是说应用程序不必在xadatasource[XA]连接上调用

第二种方式:Atomikos + Druid
atomikos支持一个分布式事务，结合spring，可以很好的满足一个应用访问多个库的需要。
Spring多数据源分布式事务管理/springmvc+spring+atomikos[jta]+druid+mybatis http://www.codexiu.cn/mysql/blog/10637/, 这里有bean继承方式配置, 配置有所修改: 执行成功之后, 记录数多的时候很慢,超过10w条记录,可能会出现连接关闭异常

    </bean>

    <bean id="springTransactionManager"
          class="org.springframework.transaction.jta.JtaTransactionManager">
        <property name="transactionManager">
            <ref bean="atomikosTransactionManager" />
        </property>
        <property name="userTransaction">
            <ref bean="atomikosUserTransaction" />
        </property>
        <property name="allowCustomIsolationLevels" value="true"/>
    </bean>
    <tx:annotation-driven transaction-manager="springTransactionManager" proxy-target-class="true"/>
</beans>

对非主数据库的DAO, 要手动注入相应的SqlSessionTemplate

配置方式: 推荐这种方式
applicationContext-mybatis-atomikos-dao.xml 

<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://www.springframework.org/schema/beans"  
       xmlns:tx="http://www.springframework.org/schema/tx"  
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
       xmlns:aop="http://www.springframework.org/schema/aop"  
       xsi:schemaLocation="http://www.springframework.org/schema/beans  
        http://www.springframework.org/schema/beans/spring-beans.xsd  
        http://www.springframework.org/schema/aop  
        http://www.springframework.org/schema/aop/spring-aop.xsd  
        http://www.springframework.org/schema/tx  
        http://www.springframework.org/schema/tx/spring-tx.xsd">  
    <!-- 因为这里使用了第二个数据库, 所以不能使用注解, 注解会注入sqlSessionTemplate, 而不是注入sqlSessionTemplateB, 会提示找不到Mapped Statements  -->  
    <bean id="testAtomikosBDao" class="com.pandy.framework.base.atomikos.dao.impl.TestAtomikosBDaoImpl">  
        <property name="sqlSessionTemplate" ref="sqlSessionTemplateB"/>  
    </bean>  
</beans>

 


注解方式: 为测试, 可能无法使用这种方式 

@Repository("testAtomikosBDao")  
public class TestAtomikosBDaoImpl{  
    @Resource(name="sqlSessionTemplateB")  
    private SqlSessionTemplate sqlSessionTemplate;  
}
