Spring MVC + Hibernate: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

本文介绍了Spring MVC + Hibernate: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的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我知道之前已经讨论过这个主题，但是不幸的是，我所遇到的解决方案都无法解决我的问题，而且我已经为此花了好几天的时间了.

I know this topic has been discussed before, but unfortumately none of the solutions I saw works in my case, and I've been breaking my head on this for days now.

我有一个典型的spring-mvc Web应用程序，具有两个上下文，servlet-context和application-conext:

I have a typical spring-mvc web app with two contexts, servlet-context and application-conext:

这是 web.xml :

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 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_2_5.xsd">

<!-- The definition of the Root Spring Container shared by all Servlets and Filters -->

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:/META-INF/spring/application-context.xml</param-value>
</context-param>

<!-- Creates the Spring Container shared by all Servlets and Filters -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- Processes application requests -->
<servlet>

</servlet>

<servlet-mapping>
    <servlet-name>appServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

</web-app>

servlet-context.xml :

</bean>

<bean id="transactionManager"
    class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

</beans>

在通过URL查询用户#1时出现以下错误:http://localhost:8080/CookIt/user?id=1:

I get the following error when querying for user #1, by the url: http://localhost:8080/CookIt/user?id=1:

这是怎么了?

感谢一堆！

推荐答案

您尚未配置事务:

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

<tx:advice id="txAdvice">
    <tx:attributes>
        <tx:method name="*" propagation="REQUIRED" />
    </tx:attributes>
</tx:advice>

<aop:config>
    <aop:advisor pointcut="execution(* YOUR.PACKAGE..*.*(..))" advice-ref="txAdvice" />
</aop:config>

此外，您需要在web.xml中指定一个过滤器

Also, You need to specify a filter in your web.xml

<filter>
    <filter-name>hibernateFilter</filter-name>
    <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>hibernateFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

此过滤器将Hibernate会话扩展到视图.

This filter extends Hibernate session to the view.
