我们正在使用带有spring和2个不同mysql数据源的atomikos JTA.

我们遇到了问题,

当我们在同一个@Transactional方法上使用两个不同的存储库(2个不同的数据源)时,我们得到一个错误：

Caused by: java.sql.SQLException: Unable to enlist connection the transaction

当第二个存储库对数据源执行某些操作时会发生这种情况.

我们认为它与事务管理器(atomikos jta)有关,当同一事务中涉及2个不同的数据源时,它可能会出现问题.

这是数据源xml：

新配置是：

            <prop key="password">xxx</prop>
        </props>
    </property>
</bean>

解决方法:

<tx:annotation-driven proxy-target-class="true" />

<tx:jta-transaction-manager
    transaction-manager="atomikosTransactionManager" />

<tx:annotation-driven transaction-manager="atomikosTransactionManager"
    proxy-target-class="true" />

<bean id="atomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager"
    init-method="init" destroy-method="close">
    <property name="forceShutdown" value="false" />
</bean>

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

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

您的配置存在缺陷,并且包含重复,这可能会让春天感到困惑. JtaTransactionManager以及< tx：jta-transaction-manager />创建一个JtaTransactionManager.

接下来你的< tx：annotation-driven>应该指向一个JtaTransactionManager但是它指向一个UserTransactionManager.

首先修复你的配置：

<tx:annotation-driven proxy-target-class="true" />

<bean id="atomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager"
    init-method="init" destroy-method="close">
    <property name="forceShutdown" value="false" />
</bean>

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

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

假设您使用的是最近的Spring 3.2版本而不是注入dataSource属性,请在LocalContainerEntityManagerFactoryBean上注入jtaDataSource,接下来可以清理jpaProperties和jpaPropertiesMap.

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="jtaDataSource" ref="xaDataSource" />
    <property name="packagesToScan" value="com.xxx.model" />
    <property name="jpaProperties">
        <props>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
            <prop key="hibernate.transaction.manager_lookup_class">com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup</prop>
        </props>
    </property>
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="databasePlatform" value="org.hibernate.dialect.MySQL5Dialect" />
            <property name="showSql" value="false" />
            <property name="generateDdl" value="false" />
        </bean>
    </property>
</bean>

在注入Spring托管数据源时,hibernate.connection属性是无用的.由于注入了jtaDataSource,可以删除javax.persistence.transactionType的jpaProperty. HibernateJpaVendorAdapter已经设置了HibernateJpaDialect,您可以使用databasePlatform属性来指定方言.

关于您的数据源,您应该使用Atomikos数据源包装器,以便他们了解Atomikos.为此,使用AtomikosDataSourceBean而不是xa为JDBC驱动程序提供的数据源.

<bean id="xaDataSource" class="com.atomikos.jdbc.AtomikosDataSourceBean" init-method="init" destroy-method="close">
    <property name="xaDataSourceClassName" value="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource" />
    <property name="uniqueResourceName" value="xaDataSource"/>      
     <property name="xaProperties">
        <props>
            <prop key="url">${mysql_url}</prop>
            <prop key="user">root</prop>
            <prop key="password">xxx</prop>
        </props>
    </property>
</bean>

最后,您使用BasicDataSource作为对hibernate的引用,而您应该使用xa启用(和包装)数据源.
