Spring @Transactional 不提交记录

Question

我使用 Spring 和 Hibernate。我正在使用以下配置。当我尝试通过 Spring 事务保存时，记录永远不会提交。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"

    <context:component-scan base-package="com.wpt.controllers,com.wpt.dao" />

    <mvc:annotation-driven />

    <mvc:default-servlet-handler />

    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass"
            value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>

    <bean id="wptDatasource" class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost:3306/wp" />
        <property name="username" value="user" />
        <property name="password" value="pass" />
    </bean>
    <bean id="hibernate4AnnotatedSessionFactory"
            class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
            <property name="dataSource" ref="wptDatasource" />
            <property name="packagesToScan" value="com.wpt.models" />
            <property name="hibernateProperties">
                <props>
                    <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                    <prop key="hibernate.current_session_context_class">thread</prop>
                    <prop key="hibernate.show_sql">false</prop>
                </props>
            </property>
        </bean>

        <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"
            p:sessionFactory-ref="hibernate4AnnotatedSessionFactory">
        </bean></beans>

我的控制器类

@Transactional
@RequestMapping(...)
public String saveRecords(@ModelAttribute("orderObj") Order order){
  for(Item item : order.getItems()){
    itemDAO.save(item);
  }
  return "saveSuccess";
}

MyDAO类

public void save(Item item){
  session = sf.openSession();
  session.save(item);
  session.close();
}

上面的@Transactional 配置没有提交记录。但是，如果我从 spring 控制器中删除 @Transactional 并使用 Hibernate 事务，如下所示，记录会提交。

public void save(Item item){
  session = sf.openSession();
  Transaction tx = session.beginTransaction();
  session.persist(item);
  tx.commit();
  session.close();
}

这个类提交记录。 我浏览了一些论坛，并提到@Transactional 将负责提交记录。我在这里犯了什么错误？有人可以帮忙吗？

提前致谢。

在我将 <tx:annotation-driven /> 注释添加到我的配置 xml 并从 hibernateSessionFactory bean 中删除 hibernate.current_session_context_class 之后，它起作用了。鉴于以下更改。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/mvc 
    http://www.springframework.org/schema/mvc/spring-mvc.xsd
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/tx 
    http://www.springframework.org/schema/tx/spring-tx.xsd">

<context:component-scan base-package="com.wpt.controllers,com.wpt.dao" />

<mvc:annotation-driven />

<mvc:default-servlet-handler />

<bean id="viewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass"
        value="org.springframework.web.servlet.view.JstlView" />
    <property name="prefix" value="/WEB-INF/views/" />
    <property name="suffix" value=".jsp" />
</bean>

<bean id="wptDatasource" class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url" value="jdbc:mysql://localhost:3306/wp" />
    <property name="username" value="user" />
    <property name="password" value="pass" />
</bean>
<bean id="hibernate4AnnotatedSessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="wptDatasource" />
        <property name="packagesToScan" value="com.wpt.models" />
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <!-- <prop key="hibernate.current_session_context_class">thread</prop> -->
                <prop key="hibernate.show_sql">false</prop>
            </props>
        </property>
    </bean>

    <tx:annotation-driven transaction-manager="transactionManager"/>
    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"
        p:sessionFactory-ref="hibernate4AnnotatedSessionFactory">
    </bean>
</beans>

然后我在我的所有服务方法中添加了org.springframework.transaction.annotation.Transactional 注释并从我的 DAO 类中删除了所有事务。

public void save(Item item){
  //session = sf.openSession();
  session.save(item);
  //session.close();
}

感谢大家的帮助。
