Question

我正在尝试构建一个可以使用Spring Boot持久化JPA和Mongo实体的应用程序。我已经用XAResource实现了MongoResourceManager和JPAResourceManager。除非显式调用entityManager.flush（），否则JPAResourceManager将不会保留数据。

JTA配置

JPA配置

<bean class="org.springframework.transaction.jta.JtaTransactionManager"
    id="transactionManager" lazy-init="true">
    <property name="transactionManager">
        <bean
            class="com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionManagerImple" />
    </property>
    <property name="userTransaction">
        <bean class="com.arjuna.ats.jta.UserTransaction" factory-method="userTransaction" />
    </property>
</bean>

JPAResourceManager

<tx:annotation-driven proxy-target-class="true" />
  <bean
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
    id="oracleEMForacle1" lazy-init="true" primary="true">
    <property name="jpaProperties">
        <props>
            <prop key="hibernate.format_sql">true</prop>
            <prop key ="hibernate.jdbc.batch_size">50</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.Oracle12cDialect</prop>
            <prop key="hibernate.transaction.jta.platform">org.hibernate.engine.transaction.jta.platform.internal.JBossStandAloneJtaPlatform
            </prop>
            <prop key="hibernate.flushMode">commit</prop>
            <prop key="hibernate.use_sql_comments">true</prop>
        </props>
    </property>
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="databasePlatform" value="org.hibernate.dialect.Oracle12cDialect" />
            <property name="generateDdl" value="true" />
            <property name="showSql" value="false" />
        </bean>
    </property>
    <property name="jtaDataSource">
        <bean class="org.apache.commons.dbcp2.BasicDataSource">
            <property name="connectionProperties"
             value="password=${password};user=${username}"></property>
            <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
            <property name="url" value="${url}" />
        </bean>
    </property>
    <property name="packagesToScan">
        <array>
            <value>com.test.jpa.jpaentity</value>   
        </array>
    </property>
</bean>

在分布式事务中使用时，JPA实体未保留
