void
decreaseMoney(Integer id,Double money);
}
AccountDaoImpl.java
package
cn.mf.dao;
import

class AccountDaoImpl extends JdbcDaoSupport implements AccountDao {
@Override
publicvoid increaseMoney(Integer id, Double money) {
getJdbcTemplate().update("update account set money = money+? where id = ? ", money,id);
}
@Override
publicvoid decreaseMoney(Integer id, Double money) {
