Mybatis-Plus 开发技巧

A and (B or C) 问题

使用LambdaQueryWrapper查询时，and和or不能直接拼接，需要用下面这种写法

LambdaQueryWrapper userLambdaQueryWrapper = new LambdaQueryWrapper()
                .and(lambda -> lambda
                                .in(User::getId, userIdSet)
                                .ge(User::getCreateTime, currentDate)
                                .or()
                                .in(User::getId, examineIdSet))
                .like(StringUtils.isNotEmpty(name), User::getName, name);

这个LambdaQueryWrapper相当于

select * from user where ((id in xxx and create_time >= xxx) or id in xxx) and name like xxx
