Spring配置文件中关于事务配置

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：

Java代码  

1. package com.dao;   
2. public interface UserDao {   
3.     public void getUser();     
4. }  

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

实现：

Java代码  

1. package com.dao.impl;   
2. import org.springframework.orm.hibernate3.support.HibernateDaoSupport;   
3. import com.dao.UserDao;   
4. public class UserDaoImpl extends HibernateDaoSupport implements UserDao {   
5.     public void getUser(){         
6.     }      
7. }  

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：

        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
</beans>

如果使用了注解，那么实现类应该这样写：

Java代码  

1. package com.dao.impl;   
2. import org.springframework.orm.hibernate3.support.HibernateDaoSupport;   
3. import org.springframework.stereotype.Component;   
4. import org.springframework.transaction.annotation.Transactional;   
5. import com.dao.UserDao;   
6. @Transactional  
7. @Component("userDaoAgency")   
8. public class UserDaoImpl extends HibernateDaoSupport implements UserDao {   
9.     /**  
10.      * 为方法增加事务处理特性  
11.      */  
12.     @Transactional(readOnly=true)   
13.     public void getUser(){         
14.     }      
15. }  

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！
