Question

我遇到了一个奇怪的问题，我的实体经理没有提交到数据库。我已经检查了我的日志，没有发现任何错误，查询似乎执行得很好。来自JPATransactionManager的调试语句表明它正在调用该方法并尝试合并/持久但是我没有显示hibernate insert语句日志中。

使用Jboss 6.1.0和Spring 3.1.1

的web.xml：

 ` <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
      http://java.sun.com/xml/ns/javaee
      http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    metadata-complete="true">
    <display-name>spring-intel</display-name>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:META-INF/spring/applicationContext*.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>IntelWsClient</servlet-name>
        <servlet-class>com.ijet.service.intel.IntelWsDriver</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>IntelWsClient</servlet-name>
        <url-pattern>/IntelWsClient</url-pattern>
    </servlet-mapping>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>


</web-app>

的applicationContext.xml：

<context:component-scan base-package="com.pwo.dao" />
<context:annotation-config/>
<tx:annotation-driven transaction-manager="txManager"/>
<bean  class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />


<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
    <property name="persistenceUnitName" value="myPU" />

</bean>


<bean id="txManager" class="org.springframework.transaction.jta.JtaTransactionManager">
    <property name="transactionManagerName" value="java:TransactionManager"/>
    <property name="userTransactionName" value="UserTransaction"/>
</bean>


</beans>

存储库类：

@Service("myService")
public class MyServiceImpl implements MyService {

@PersistenceContext
EntityManager em;

public void setEntityManager(EntityManager em) {
    this.em = em;
}


@Transactional(propagation = Propagation.SUPPORTS)
public Item findItem(Integer itemId) {
    return em.find(Item.class, itemId);
}

@Transactional(propagation = Propagation.REQUIRED)
public void storeItem(Item item) {
    if (item != null && item.getId() != null) {
        em.merge(item);
    } else
        em.persist(item);

    em.flush();
}
}

的persistence.xml

  <persistence-unit name="myPU" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:pwo-DS</jta-data-source>
    <exclude-unlisted-classes>true</exclude-unlisted-classes>
 <properties> 
  <property name="hibernate.validator.autoregister_listeners" value="false"/>
  <property name="hibernate.dialect" value="org.hibernate.dialect.OracleDialect"/>  
  <!--property name="hibernate.cache.use_query_cache" value="false"/-->
  <property name='hibernate.cache.provider_class' value='org.hibernate.cache.EhCacheProvider'/>
  <property name="hibernate.show_sql" value="true"/>
   <property name="hibernate.order_inserts" value="true"/>
    <property name="hibernate.order_updates" value="true"/>
    <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
</properties>

JTATransactionManager报告成功提交但数据库中没有记录
