可以的呀，同學(xué)。可以這樣寫，例如：query.select(User.class, info->info.getColumn().equals("id"));

query.select(User.class, !info->info.getColumn().equals("id"));

這樣寫排除不了id，結(jié)果集id還是會(huì)顯示出來。

@Test
public?void?selectPartOfColumns(){
????QueryWrapper<User>?qw?=?new?QueryWrapper<>();
????qw.like("name","雨").gt("age",20)
????????????.select(User.class,c?->?!c.getColumn().equals("id")
????????????);
????List<User>?list?=?userMapper.selectList(qw);
????list.forEach(System.out::println);
}
