控制臺報的SQL語法錯誤,很奇怪
自己在DEBUG模式下運行,程序執(zhí)行到MaintainService下的deleteBatch下的dao.deleteBatch(idList)就報錯
下面是報錯的部分信息:
<==????? Total: 3
==>? Preparing: delete form MESSAGE where ID in( ? , ? )
==> Parameters: 2(Integer), 3(Integer)

找到問題所在了,原因是sql語句寫錯了應(yīng)該是from 寫成了 form
總結(jié)3點想分享給一起努力小伙伴:1.學(xué)會使用DEBUG,這是個好東西
2.心細(xì)
3.遇到一時解決不了的問題,學(xué)會像別人求助或者放一下,讓自己休息一下再來看,效率會高很多。
