Spring/Hibernate异常：没有活动事务，createCriteria无效。

Question

我花了几天时间解决一个spring-hibernate-transaction的问题。我创建了一个简单的WebService，使用jaxws + spring + hibernate，它工作得很好，但是当我调用使用事务bean的Web方法时，Spring抛出了以下错误：

21 sept. 2011 14:29:29 com.sun.xml.ws.server.sei.EndpointMethodHandler invoke
GRAVE: org.hibernate.HibernateException: createCriteria is not valid without active transaction

我看起来交易已经开始了...但是出现了一些问题。

这是我的应用上下文：

<context:annotation-config/>

    <!-- List of packages managed by Spring -->
    <context:component-scan base-package="..." />

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://xxxx"/>
        <property name="username" value="xxx"/>
        <property name="password" value="xxx"/>
    </bean>

    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="packagesToScan" value="xxxx"/>
        <property name="dataSource" ref="dataSource"/>
        <property name="configLocation" value="classpath:hibernate.cfg.xml" />
    </bean>

    <tx:annotation-driven transaction-manager="transactionManager" />
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

以下是 hibernate.cfg.xml 文件的内容：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

        <property name="hibernate.format_sql">true</property>

        <property name="hibernate.jdbc.batch_size">20</property>
        <!-- Bind the getCurrentSession() method to the thread. -->
        <property name="current_session_context_class">thread</property>
        <property name="hibernate.cache.provider_class">net.sf.ehcache.hibernate.SingletonEhCacheProvider</property>
        <property name="hibernate.cache.use_second_level_cache">true</property>
        <property name="hibernate.cache.use_query_cache">true</property>

        <!-- Lucene Search -->
        <property name="hibernate.search.default.directory_provider">org.hibernate.search.store.RAMDirectoryProvider</property>

    </session-factory>

我把这个Web应用部署在Tomcat6上。 希望您能帮助我解决这个问题。

谢谢。

你确定你的bean/method有@Transactional注解吗？并且同一个bean在Spring上下文中被调用和管理了吗？ - Michael Pralow

是的，我的bean被@ Transactional注释，并由Spring管理。 - juliusdev

Answer 1

好的，我找到问题所在了！我从Hibernate配置中删除了这一行。 Spring管理事务，并且不需要会话保持在Hibernate线程中。

<!-- Bind the getCurrentSession() method to the thread. -->
<property name="current_session_context_class">thread</property>
