使用mybatis-generator.xml 生成PO 物件

阿新 • • 發佈：2021-10-30

問題是,開發了一箇舊專案改造,以前是jsp,現在改為前後端分離,以前的增刪改查還是用的以前的BL,BL是用的Schema生成的,

那麼現在進行一次轉換

CREATE TABLE `lawagecalelement` (
  `RiskCode` varchar(10) NOT NULL,
  `CalType` char(2) NOT NULL,
  `F1` varchar(10) DEFAULT NULL,
  `F2` varchar(10) DEFAULT NULL,
  `F3` varchar(10) DEFAULT NULL,
  `F4` varchar(10) DEFAULT NULL,
  `F5` varchar( 
10) DEFAULT NULL,
  `CalCode` varchar(6) DEFAULT NULL,
  `BranchType` varchar(2) NOT NULL,
  `BranchType2` varchar(2) NOT NULL,
  `CalOrder` int(2) DEFAULT NULL,
  PRIMARY KEY (`RiskCode`,`CalType`,`BranchType`,`BranchType2`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

命名為:mybatis-generator.xml
