spring
如果容器支持jta，那么spring配置起來非常簡單，因?yàn)閟pring提供了JtaTransactionManager，在這里面提供了幾乎所有的服務(wù)器的jta的jndi名字，比如
* "java:comp/UserTransaction" for Resin 2.x, Oracle OC4J (Orion), JOnAS (JOTM), BEA WebLogic
* "java:comp/TransactionManager" for Resin 3.x
* "java:appserver/TransactionManager" for GlassFish
* "java:pm/TransactionManager" for Borland Enterprise Server and Sun Application Server (Sun ONE 7 and later)
* "java:/TransactionManager" for JBoss Application Server
由于大部分服務(wù)器獲取jta的方式都不盡相同，spring還針對不同的服務(wù)器提供了不同的jta實(shí)現(xiàn)，例如：
WebLogicJtaTransactionManager
WebSphereUowTransactionManager
OC4JJtaTransactionManager
具體內(nèi)容參加：
http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/transaction/jta/JtaTransactionManager.html
不管是jdbc、hibernate還是ibatis，都可以通過JtaTransactionManager來配置分布式事務(wù)
下面簡單貼出部分配置代碼：
hibernate：
<beans>
<jee:jndi-lookup id="myDataSource1" jndi-name="dsjndi1" />
<jee:jndi-lookup id="myDataSource2" jndi-name="dsjndi2" />
<bean id="mySessionFactory1"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource">
<ref bean="myDataSource1" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hiberante.format_sql">true</prop>
</props>
</property>
<property name="annotatedClasses">
<list>
<value>com.landor.test.entity.User</value>
</list>
</property>
<property name="annotatedPackages">
<list>
<value>com.landor.test.entity</value>
</list>
</property>
</bean>
<bean id="mySessionFactory2"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource">
<ref bean="myDataSource2" />
</property>
</bean>
<bean id="myTxManager" class="org.springframework.transaction.jta.JtaTransactionManager"/>
<!--如果默認(rèn)id=transactionManager，那么可以有下面的標(biāo)簽，這樣spring會自動尋找相應(yīng)的jta的jndi并且注入
<tx:jta-transaction-manager/>-->
<tx:advice id="txAdvice" transaction-manager="myTxManager">
<tx:attributes>
<tx:method name="select*" read-only="true" propagation="REQUIRED"/>
<tx:method name="find*" read-only="true" propagation="REQUIRED"/>
<tx:method name="save*" propagation="REQUIRED" isolation="REPEATABLE_READ"/>
<tx:method name="update*" propagation="REQUIRED" isolation="REPEATABLE_READ"/>
<tx:method name="add*" propagation="REQUIRED" isolation="REPEATABLE_READ" />
<tx:method name="delete*" propagation="REQUIRED" isolation="REPEATABLE_READ"/>
</tx:attributes>
</tx:advice>
</beans>
ibatis：
ibatis與hibernate是一樣的，只需要將hibernate的sessionFactory部分更換一下
......
<bean id="sqlMap1Client"
class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="dataSource" ref="myDataSource1" />
<property name="configLocation" value="xxx/SqlMapConfig.xml" />
</bean>
<bean id="sqlMap2Client"
class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="dataSource" ref="OssDS" />
<property name="configLocation" value="xxx/SqlMapConfig.xml" />
</bean>
