Java 没有 Hibernate Session 绑定到线程，并且配置不允许在此处创建非事务性会话

No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here

提问by chedine

What is this error about? "No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here". My spring config file looks something like this.

这个错误是关于什么的？“没有 Hibernate Session 绑定到线程，并且配置不允许在此处创建非事务性会话”。我的 spring 配置文件看起来像这样。

<bean id="jndiDataSource"
    class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName">
        <value>java:/devDS</value>
    </property>
</bean>
<bean id="stsaDBFactory"
    class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="jndiDataSource" />
    <property name="annotatedClasses">
        <list>
            <value>xx.yy.zz.User</value>
            <value>xx.yy.UserResponse</value>

        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbmddl.auto">create</prop>
        </props>
    </property>
</bean>

All the DAO test passes when i test them outside of the container using junit. When I deploy it in jBoss as a portal app,I get this exception. Also it works fine if i remove the portal specific configuration and make it a simple web app and deploy it on jboss.Any idea?

当我使用 junit 在容器外测试它们时，所有 DAO 测试都通过了。当我将它作为门户应用程序部署在 jBoss 中时，出现此异常。如果我删除特定于门户的配置并使其成为一个简单的 Web 应用程序并将其部署在 jboss 上，它也可以正常工作。有什么想法吗？

You have defined a TransactionManager in your spring config but you are trying to execute a hibernate query in a method that is not transactional. Try adding @Transactional to your method or class.

您已经在 spring 配置中定义了一个 TransactionManager，但您试图在非事务性方法中执行休眠查询。尝试将 @Transactional 添加到您的方法或类中。

I got around this problem by specifying the current_session_context_classin hibernate configto be "thread", as per the simple configuration shown in the hibernate configuration documentation.

根据休眠配置文档中显示的简单配置，我通过将current_session_context_classin指定hibernate config为“ thread”来解决这个问题。

But it recommends that its not safe for production usage.

但它建议它对于生产使用不安全。

Trying to add the following in your hibernate configshould also help:

尝试在您的内容中添加以下内容hibernate config也应该有所帮助：

<property name="current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property>
