使用JDBC编写事务

public class TestTranslation {
    public static void main(String[] args) {
        Connection conn = null;
        PreparedStatement stmt = null;
        ResultSet rs = null;

        try {
            conn = JDBCUtils.getConn();
            conn.setAutoCommit(false);//关闭自动提交开启事务

            String sql = "update account set money = money+100 where id = 1";
            String sql1 = "update account set money = money-100 where id = 2";

            stmt = conn.prepareStatement(sql);
            stmt.executeUpdate();

            stmt = conn.prepareStatement(sql1);
            stmt.executeUpdate();

            conn.commit();//提交事务
            System.out.println("成功！！");


        } catch (SQLException e) {
            try {
                conn.rollback(); //事务失败默认会回滚，这里不写也会回滚！
            } catch (SQLException ex) {
                ex.printStackTrace();
            }
            e.printStackTrace();
        }
        finally {
            JDBCUtils.release(conn,stmt,null);
        }
    }
}
