前段时间对Spring的事务配置做了比较深入的研究,在此之间对Spring的事务配置虽说也配置过,但是一直没有一个清楚的认识。通过这次的学习发觉Spring的事务配置只要把思路理清,还是比较好掌握的。
总结如下:
Spring配置文件中关于事务配置总是由三个组成部分,分别是DataSource、TransactionManager和代理机制这三部分,无论哪种配置方式,一般变化的只是代理机制这部分。
DataSource、TransactionManager这两部分只是会根据数据访问方式有所变化,比如使用Hibernate进行数据访问 时,DataSource实际为SessionFactory,TransactionManager的实现为 HibernateTransactionManager。
具体如下图:
根据代理机制的不同,总结了五种Spring事务的配置方式,配置文件如下:
第一种方式:每个Bean都有一个代理

第五种方式:全注解

此时在DAO上需加上@Transactional注解,如下:
package
com.bluesky.spring.dao;
import java.util.List;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Component;
import com.bluesky.spring.domain.User;
@Transactional
@Component( " userDao " )
public class UserDaoImpl extends HibernateDaoSupport implements UserDao {
public List < User > listUsers() {
return this .getSession().createQuery( " from User " ).list();
}
}
import java.util.List;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Component;
import com.bluesky.spring.domain.User;
@Transactional
@Component( " userDao " )
public class UserDaoImpl extends HibernateDaoSupport implements UserDao {
public List < User > listUsers() {
return this .getSession().createQuery( " from User " ).list();
}
}
