Spring 配置 事务的几种方式

源：http://cuisuqiang.iteye.com/blog/1508965

评：

Spring配置文件中关于事务配置总是由三个组成部分，DataSource、TransactionManager和代理机制这三部分，无论是那种配置方法，一般变化的只是代理机制这块！

 

首先我创建了两个类，一个接口一个实现：

package com.dao;
public interface UserDao {
    public void getUser();
}

 

实现：

package com.dao.impl;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.dao.UserDao;
public class UserDaoImpl extends HibernateDaoSupport implements UserDao {
    public void getUser(){
    }
}

 

 

第一种：每个Bean都有一个代理：

第五种：注解：

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

           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.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://192.168.0.244:3306/test?useUnicode=true&amp;characterEncoding=UTF-8" />
        <property name="username" value="root" />
        <property name="password" value="root" />
        <!-- 连接池启动时的初始值 -->
        <property name="initialSize" value="10" />
        <!-- 连接池的最大值 -->
        <property name="maxActive" value="10" />
        <!-- 最大空闲值.当经过一个高峰时间后，连接池可以慢慢将已经用不到的连接慢慢释放一部分，一直减少到maxIdle为止 -->
        <property name="maxIdle" value="20" />
        <!--  最小空闲值.当空闲的连接数少于阀值时，连接池就会预申请去一些连接，以免洪峰来时来不及申请 -->
        <property name="minIdle" value="10" />
        <property name="defaultAutoCommit" value="true" />
    </bean>
    <!-- 会话工厂 -->
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="mappingLocations">
            <list>
                <value>classpath:/com/nms/entity/**/*.hbm.xml</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">
                    org.hibernate.dialect.MySQL5Dialect
                </prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
            </props>
        </property>
    </bean>
    <context:annotation-config />
    <!-- 使用注解的包路径 -->
    <context:component-scan base-package="com.dao" />
    <!-- 支持  @Transactional 标记 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>
    <!-- 定义事务管理器 -->
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
</beans>

 

如果使用了注解，那么实现类应该这样写：

package com.dao.impl;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;
import com.dao.UserDao;
@Transactional
@Component("userDaoAgency")
public class UserDaoImpl extends HibernateDaoSupport implements UserDao {
    /**
     * 为方法增加事务处理特性
     */
    @Transactional(readOnly=true)
    public void getUser(){
    }
}

 

这样每个方法都能自己定义自己的事务处理！
