私たちは、Spring と 2 つの異なる mysql データソースで atomikos JTA を使用しています。

問題が発生しました。

同じ @Transactional メソッドで (2 つの異なるデータソースの) 2 つの異なるリポジトリを使用すると、エラーが発生します。

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

これは、2 番目のリポジトリがデータ ソースに対して何らかのアクションを実行しているときに発生します。

2 つの異なるデータ ソースが同じトランザクションに関係している場合に問題が発生する可能性があるトランザクション マネージャー (atomikos jta) と関係があると考えられます。

構成に欠陥があり、重複が含まれているため、おそらく春が混乱します。との両方JtaTransactionManagerを<tx:jta-transaction-manager />作成しJtaTransactionManagerます。

次に、<tx:annotation-driven >a を指す必要がありますが、JtaTransactionManagerそれは a を指す必要はありませんUserTransactionManager。

したがって、最初に構成を修正します。

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

dataSourceプロパティを注入する代わりに、最近のSpring 3.2バージョンを使用していると仮定すると、次にあなたのjtaDataSourceandをクリーンアップできます。LocalContainerEntityManagerFactoryBeanjpaPropertiesjpaPropertiesMap

<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>

hibernate.connectionSpring 管理のデータソースを注入しているため、プロパティは役に立ちません。jtaDataSourcejpaPropertyの注入により、javax.persistence.transactionType削除することができます。はHibernateJpaVendorAdapterすでに を設定してHibernateJpaDialectおり、プロパティを使用しdatabasePlatformて方言を指定できます。

データソースに関しては、Atomikos を認識できるように、データソースに Atomikos ラッパーを使用する必要があります。これAtomikosDataSourceBeanには、JDBC ドライバー用の xa 提供のデータソースの代わりに を使用します。

<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>

最後にBasicDataSource、休止状態への参照として を使用していますが、xa 対応 (およびラップされた) データソースを使用する必要があります。

これを試してください: トランザクション マネージャーに以下を追加します。

<qualifier value="transactionManager1"/>

例：

<bean id="transactionManager1" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory1" />
    <qualifier value="transactionManager1"/>
</bean>

次に、DAO 実装で次のようにします。

@Repository("Users1DAO")
public class Users1DAOJpaImp implements Users1DAO {
