###  AccountServiceImpl.java ###

注解添加在类上，所有方法都采取这个策略。如果类上，方法上都写注解，以方法上的为主。

package spring.tx;
    
    import org.springframework.transaction.annotation.Isolation;
    import org.springframework.transaction.annotation.Propagation;
    import org.springframework.transaction.annotation.Transactional;
    
    @Transactional(isolation=Isolation.REPEATABLE_READ,propagation=Propagation.REQUIRED,readOnly=false)
    public class AccountServiceImpl implements AccountService{
    	private AccountDao ad ;
    	
    	@Override
    	public void transfer(Integer from, Integer to, Double money) {
    		ad.addMoney(from,money);
    		int a = 1/0;
    		ad.loseMoney(to,money);
    	}
    
    	
    	public void setAd(AccountDao ad) {
    		this.ad = ad;
    	}
    
    }
