我们的应用程序当前使用的是JBoss standalone.xml中定义的数据源,基本上我们需要在应用程序中定义它,而不是在容器中定义一段时间。我们目前的设置是;
应用context.xml中;
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml" />
<property name="persistenceUnitName" value="rtsPersistenceUnit" />
<property name="packagesToScan">
...
</property>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="database" value="ORACLE" />
<property name="databasePlatform" value="org.hibernate.dialect.Oracle10gDialect"/>
</bean>
</property>
</bean>
persistance.xml:
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
version="2.0">
<persistence-unit name="rtsPersistenceUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:/jdbc/RTSdb</jta-data-source>
<class>...</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.hbm2ddl.auto" value="validate" />
<property name="hibernate.transaction.flush_before_completion" value="true" />
</properties>
</persistence-unit>
</persistence>
datasource.xml:
<bean id="rtsDatasource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="oracle.jdbc.OracleDriver"/>
<property name="url" value="..."/>
<property name="username" value="..."/>
<property name="password" value="..."/>
</bean>
基本上我想要的只是行
<jta-data-source>java:/jdbc/RTSdb</jta-data-source>
从datasource.xml读取而不是去容器(JBoss)。 看起来它很简单,但在阅读了一些Spring和Oracle文档后,我找不到答案。

是的,您可以使用符合JTA标准的事务管理器,如Atomikos或Bitronix。他们各自的站点都有关于如何使用Spring配置它们的文档。通常,您必须按照下面给出的步骤(如果使用Atomikos):
rtsDatasource
)或创建一个(如果尚未使用)(例如,如果有人拥有非XA数据源,则必须将该数据源转换为XA数据)来源第一)。AtomikosDataSourceBean
。EntityManagerFactory
指向新AtomikosDataSourceBean
个实例。JtaTransactionManager
。JtaTransactionManager
。使用H2数据库,Hibernate 4,Spring 4和Atomikos 4的简短配置片段如下所示。
<bean class="org.h2.jdbcx.JdbcDataSource" id="originalDataStore" lazy-init="true">...</bean>
<bean class="com.atomikos.jdbc.AtomikosDataSourceBean" id="dataSource" init-method="init" destroy-method="close">
<property name="uniqueResourceName" value="xaDS"/>
<property name="xaDataSource" ref="originalDataStore"/>
<property name="poolSize" value="3"/>
</bean>
<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory">
<property name="dataSource" ref="dataSource"/>
<property name="jpaProperties">
<props>
<prop key="hibernate.transaction.jta.platform">com.atomikos.icatch.jta.hibernate4.AtomikosPlatform</prop>
...
</props>
</property>
</bean>
<bean class="org.springframework.transaction.jta.JtaTransactionManager" id="transactionManager">
<property name="transactionManager">
<bean class="com.atomikos.icatch.jta.UserTransactionManager" init-method="init" destroy-method="close">
<property name="forceShutdown" value="false"/>
</bean>
</property>
<property name="userTransaction">
<bean class="com.atomikos.icatch.jta.J2eeUserTransaction">
<property name="transactionTimeout" value="300"/>
</bean>
</property>
<property name="allowCustomIsolationLevels" value="true"/>
</bean>
<transaction:annotation-driven transaction-manager="transactionManager"/>
