jotm跨数据库 事务
jotm跨数据库 spring + hibernate


软件包
ow2-jotm-dist-2.1.9-bin.tar.gz
spring-framework-3.0.5.RELEASEhibernate-3.6.0.Final
hibernate-3.6.0.Final

spring和hibernate不再详述，讲讲jotm如何与spring集成
web开发中，使用hibernate的SessionFactory，而在SessionFactory中注入DataSource
DataSource需要支持事务，因此采用软件包ow2-jotm-dist-2.1.9-bin.tar.gz中的xapool.jar包来配置DataSource，放弃了org.springframework.jdbc.datasource.DriverManagerDataSource

配置jta事务管理器JtaTransactionManager
重点<property name="userTransaction" ref="jotm" />

    <bean id="jotm" class="org.springframework.transaction.jta.JotmFactoryBean" /> 
        <bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager"> 
            <property name="userTransaction" ref="jotm" /> 
            <property name="allowCustomIsolationLevels" value="true"></property> 
        </bean>
