Spring的事务管理(注解)

注解与XML配置的主要差别在配置文件和service中。所以这里只上主要代码，其他参考这里  

service

package com.kye.serviceImpl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.kye.dao.AccountDao;
import com.kye.service.AccountService;

@Service("service")
public class AccountServiceImpl implements AccountService {

	@Autowired
	@Qualifier("accountDao")
	AccountDao dao;

	public void setDao(AccountDao dao) {
		this.dao = dao;
	}

	@Transactional
	@Override
	public void transfer(int monehy) {
		dao.add(monehy);
		 int a = 1 / 0;
		dao.add(monehy);
	}

	@Override
	public int get() {
		return dao.get();
	}

}
