You have an error in your SQL syntax

原数据库语句如下：

  insert into order (oid, sid, mid, cid, `number`, price)
  values (#{oid}, #{sid}, #{mid}, #{cid}, #{number}, #{price})

要注意，order在SQL中是关键字，所以需将代码修改如下：

  insert into `order` (oid, sid, mid, cid, `number`, price)
  values (#{oid}, #{sid}, #{mid}, #{cid}, #{number}, #{price})
