Spring与Hibernate的整合，不配置事务管理器，事务会自动提交（Hibernate默认手动提交）

数据库为MySQL，Spring版本3.2.1，Hibernate版本3.3.2。

Spring配置文件：

<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans"         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://www.springframework.org/schema/beans                              http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">             <!-- 数据源 -->      <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://localhost:3306/test"/>          <property name="username" value="root"/>          <property name="password" value="xxxxxx"/>        <property name="initialSize" value="1"></property>        <property name="maxActive" value="100"></property>        <property name="maxIdle" value="2"></property>        <property name="minIdle" value="1"></property>    </bean>            <!-- sessionFactory -->      <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">          <property name="dataSource" ref="dataSource" />          <property name="mappingResources">              <list>                 <value>com/zzj/entity/Config.hbm.xml</value>              </list>          </property>        <property name="hibernateProperties">              <value>                  hibernate.dialect=org.hibernate.dialect.MySQLDialect                hibernate.show_sql=true            </value>          </property>      </bean>         <!-- Dao -->     <bean id="configDao" class="com.zzj.dao.ConfigDao">    <property name="sessionFactory" ref="sessionFactory"/>    </bean>      </beans>  

实体类：

package com.zzj.entity;public class Config {private Integer id;private String name;private String value;public Config() {}public Config(Integer id, String name, String value) {this.id = id;this.name = name;this.value = value;}public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getValue() {return value;}public void setValue(String value) {this.value = value;}@Overridepublic String toString() {return "Config [id=" + id + ", name=" + name + ", value=" + value + "]";}}

Hibernate映射文件：

<?xml version="1.0" encoding="UTF-8"?>    <!DOCTYPE hibernate-mapping PUBLIC            "-//Hibernate/Hibernate Mapping DTD 3.0//EN"            "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">  <hibernate-mapping>      <class name="com.zzj.entity.Config" table="config">        <id name="id" column="id">            <generator class="identity" />        </id>        <property name="name" column="name" />        <property name="value" column="value" />    </class></hibernate-mapping>

Dao类：

package com.zzj.dao;import java.sql.SQLException;import org.hibernate.HibernateException;import org.hibernate.Query;import org.hibernate.Session;import org.springframework.orm.hibernate3.HibernateCallback;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;public class ConfigDao extends HibernateDaoSupport {public void save(){getHibernateTemplate().execute(new HibernateCallback<Integer>() {@SuppressWarnings("deprecation")@Overridepublic Integer doInHibernate(Session session) throws HibernateException, SQLException {System.out.println("autoCommit:" + session.connection().getAutoCommit());Query query = session.createQuery("update Config set value = :value where name = :name");query.setString("name", "Tom");query.setString("value", "11");return query.executeUpdate();}});}}

测试类：

package com.zzj;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.zzj.dao.ConfigDao;public class Test {public static void main(String[] args) {ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-common.xml");ConfigDao configDao = (ConfigDao) context.getBean("configDao");configDao.save();}}

Spring没有配置事务管理器，Dao类中也没有开启和提交事务的操作，事务也提交了！

注意：Dao类中输出的autoCommit为true。
