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:

第四种:使用tx标签配置的拦截器:

	<!-- 定义事务管理器 -->  
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">

    </bean>
    <!-- 定义事务 -->

        <aop:advisor advice-ref="txAdvice" pointcut-ref="interceptorPointCuts" />
    </aop:config>
</beans>

 

 

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/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd
           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
           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!
