xa distributed transaction manager example 4

If the container supports jta, then spring configuration is very simple, because spring provides JtaTransactionManager, which provides the jndi name of jta for almost all servers, such as

* "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 

Since most servers get jta in different ways, spring also provides different jta implementations for different servers, for example:

WebLogicJtaTransactionManager
WebSphereUowTransactionManager
OC4JJtaTransactionManager

Whether it is jdbc, hibernate or ibatis, you can configure the distribution through JtaTransactionManager The
following is a simple post for some configuration code:
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"/>
  <!--如果默认id= transactionManager，那么可以有下面的标签，这样spring会自动寻找相应的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与hibernate是一样的，只需要将hibernate的sessionFactory部分更换一下

    ......
    <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>
