LambdaQueryWrapper中and、or的用法

// WHERE xxxx!=id And ( xxxx=ANo or xxxx=BNo)
LambdaQueryWrapper<Student> queryWrapper = new LambdaQueryWrapper<>();
queryWrapper.ne(Student::getId,sysstudents.getId());
queryWrapper.and((wrapper)->{
　　wrapper.eq(Student::getANo,sysstudents.getBillNo())
　　.or().eq(Student::getBNo,sysstudents.getBillNo());
});
