具有Spring数据和Spring JPA的Atomikos-持久性问题

Question

我们正在尝试为我们的新项目设置一个新的JTA事务配置。该项目利用Spring JPA和Spring Data与atomikos JTA事务管理器。

正如在atomikos教程中看到的那样，我们配置了XML。

目前，我们设法启动我们的服务器没有错误。

问题是，当我们尝试在@Transactional服务中使用jpaRepository持久化实体时，我们的日志显示atomikos jta事务正在发生并提交成功。但我们的DB现在在表中显示新条目。

我们之前也遇到过类似的问题，当2个bean扫描相同的包时，会产生如上所述的“psuedo persist”效果。

这是我们的xml：

<bean
    class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />

<tx:annotation-driven transaction-manager="transactionManager"
    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"
    depends-on="AtomikosTransactionManager,AtomikosUserTransaction">
    <property name="transactionManager" ref="AtomikosTransactionManager" />
    <property name="userTransaction" ref="AtomikosUserTransaction" />
    <property name="allowCustomIsolationLevels" value="true" />
</bean>

<bean id="dataSource" class="com.atomikos.jdbc.AtomikosDataSourceBean"
    init-method="init" destroy-method="close">

    <property name="uniqueResourceName" value="DataSource" />
    <property name="xaDataSource" ref="dataBase" />
    <property name="poolSize" value="3" />

</bean>

<bean id="dataBase" class="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource"
    lazy-init="true">

    <property name="pinGlobalTxToPhysicalConnection" value="true" />
    <property name="url"
        value="mydb" />
    <property name="user" value="user" />
    <property name="password" value="password" />

</bean>

<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="packagesToScan"
        value="packages" />
    <property name="jpaProperties">
        <props>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
        </props>
    </property>
    <property name="dataSource" ref="dataSource" />
    <property name="jpaDialect">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
    </property>
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="database" value="MYSQL" />
            <!-- <property name="databasePlatform" value="${hibernate.dialect}"/> -->
            <property name="showSql" value="false" />
            <property name="generateDdl" value="false" />
            <!-- <property name="hibernate.connection.autocommit" value="false"/> -->
        </bean>
    </property>
    <property name="jpaPropertyMap">
        <map>
            <entry key="hibernate.connection.autocommit" value="false" />
        </map>
    </property>
</bean>

你知道这个配置文件有什么问题吗？

谢谢

原来我们在entityManagerFactory的jpaPropertyMap中缺少了一些属性。这是它的正确配置：

<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="packagesToScan"
        value="packages" />
    <property name="jpaProperties">
        <props>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
        </props>
    </property>
    <property name="dataSource" ref="dataSource" />
    <property name="jpaDialect">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
    </property>
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="database" value="MYSQL" />
            <property name="showSql" value="false" />
            <property name="generateDdl" value="false" />
        </bean>
    </property>
    <property name="jpaPropertyMap">
        <map>
            <entry key="javax.persistence.transactionType" value="JTA" />
            <entry key="hibernate.current_session_context_class" value="jta" />
            <entry key="hibernate.transaction.manager_lookup_class"
                value="com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup" />
            <entry key="hibernate.connection.autocommit" value="false" />
        </map>
    </property>
</bean>
