Question

我正在尝试在Spring Tools Suite和Pivotal tc Server Developer Edition上开发Spring + Hibernate + EntityManager + Spring Data + PostgreSQL数据库。我的配置是：的applicationContext.xml

<context:component-scan base-package="com.me, dk.me" />
<jpa:repositories base-package="dk.me.data"
    entity-manager-factory-ref="entityManagerFactory">
</jpa:repositories>
<!-- tx:jta-transaction-manager /-->
<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>
<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="persistenceUnitName" value="MyPU"/>
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
    </property>
</bean>

<bean id="transactionManager"
    class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>

我的persistence.xml是：

<persistence-unit name="MyPU" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <properties>
        <property name="hibernate.connection.driver_class" value="org.postgresql.Driver"/>
        <property name="hibernate.connection.username" value="postgres"/>
        <property name="hibernate.connection.password" value="masterkey"/>
        <property name="hibernate.connection.url" value="jdbc:postgresql://localhost:5432/postgres"/>           
        <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
        <property name = "javax.persistence.jdbc.driver" value = "org.postgresql.Driver"/>
        <property name = "javax.persistence.jdbc.url" value = "jdbc:postgresql://localhost:5432/postgres"/>
        <property name = "javax.persistence.jdbc.user" value = "postgres"/>
        <property name = "javax.persistence.jdbc.password" value = "masterkey"/>
        <!-- property name="hibernate.ejb.cfgfile" value="hibernate.cfg.xml"/-->
        <property name="hibernate.transaction.jta.platform" 
        value="org.hibernate.service.jta.platform.internal.JBossStandAloneJtaPlatform" />
    </properties>
</persistence-unit>

代码非常简单，只需调用Spring Data存储库即可读取所有bean。错误消息是：

Could not open JPA EntityManager for transaction; nested exception is java.lang.IllegalStateException: A JTA EntityManager cannot use getTransaction()

问题是 - 我的配置是否制作了一些内容，应该纠正什么。我知道有很多设计选择（例如本地与分布式事务，数据源的使用等），但我想得到与当前配置最相似的配置，以便顺利进行随着发展本身。我使用的是最新的兼容（4.x）版本的Spring和Hibernate，pom.xml中没有版本冲突，也没有mavan包或部署时间异常。在运行时发出第一个请求时会引发异常。

提前感谢您的任何建议。

您的Spring事务管理器是JpaTransactionManager

<bean id="transactionManager"
    class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>

而persistence.xml配置为使用JTA：

<persistence-unit name="MyPU" transaction-type="JTA">

您还使用对RESOURCE_LOCAL事务有意义的hibernate.connection属性。

如果您不想使用JBoss XA DataSource和JTA事务，那么只需将持久性单元transaction-type更改为RESOURCE_LOCAL：

<persistence-unit name="MyPU" transaction-type="RESOURCE_LOCAL">

并删除此属性：

<property name="hibernate.transaction.jta.platform" 
value="org.hibernate.service.jta.platform.internal.JBossStandAloneJtaPlatform" />

如果你想要JTA，那么你需要配置一个Spring JTATransactionManager并删除本地DataSource相关的hibernate.connection属性，同时使用JNDI找到JBoss XA DataSource：
```
<jta-data-source>java:/DefaultDS</jta-data-source>
```

无法打开JPA EntityManager进行事务处理。 JTA EntityManager无法使用getTransaction（）
