public interface PersonDao {
	public void savePerson();
}

@Repository("personDao")
public class PersonDaoImpl implements PersonDao{
	@Resource(name="jdbcTemplate")
	//这里这能保存jdbcTemplate变量的方式不能继承jdbcSupport	
	private JdbcTemplate jdbcTemplate;
	@Override
	public void savePerson() {
		// TODO Auto-generated method stub
		this.jdbcTemplate.execute("insert into person(pname) values('aa')");
		int a = 1/0;
		this.jdbcTemplate.execute("insert into person(pname) values('aa')");
	}
}

public interface PersonService {
	public void savePerson();
}

@Service("personService")
public class PersonServiceImpl implements PersonService{
 
	@Resource(name="personDao")
	private PersonDao personDao;
	/**
	 * 注解的粒度比xml要细
	 */
	@Transactional(readOnly=false)//这才是重点
	public void savePerson() {
		// TODO Auto-generated method stub
		this.personDao.savePerson();
	}
	
}

上面的代码才是重点

public class PersonTest extends SpringHelper{
	static{
		path = "cn/itcast/spring0909/jdbc/transaction/annotation/applicationContext.xml";
	}
	
	@Test
	public void test(){
		PersonService personService = (PersonService)context.getBean("personService");
		personService.savePerson();
	}
}
