如何使用 AutoWire方式注入 JdbcDaoSupport DataSource

@Repository
public class MyDaoImpl extends JdbcDaoSupport implements MyDao {
    @Autowired
    private DataSource dataSource;

    @PostConstruct
    private void initialize() {
        setDataSource(dataSource);
    }

    public void In(String user, double money) {
        String sql = "update account set money = money + " + money + " where name='" + user + "'";

        this.getJdbcTemplate().update(sql);

    }

    public void Out(String user, double money) {
        String sql = "update account set money = money - ?   where name=?";

        this.getJdbcTemplate().update(sql, money, user);
    }
}

备忘于此
