mybatis-plus中selectList用法

SELECT * FROM user_info WHERE tom_age = '20' and name='tom';

 等同于

QueryWrapper<UserInfo> queryWrapper = new QueryWrapper();
queryWrapper.eq("tom_age", '20');//tom_age必须是数据库中的字段
queryWrapper.eq("name",'tom');
List<UserInfo> list = userInfoMapper.selectList(queryWrapper );
