wrapper.or and 语句写法

使用Mybatis Plus的QueryWrapper实现如下的sql语句效果：

select * from xxx where field1= ? and (field2= ? or field3= ?)
Mybatis Plus代码：

QueryWrapper<xxx> queryWrapper = new QueryWrapper<xxx>();
queryWrapper.eq(field1, field1Value);
queryWrapper.and(wrapper -> wrapper.eq(field2, field2Value).or().eq(field3, field3Value));

 

SELECT * FROM `tb_track_scale_exception` n
WHERE n.`isDelete`=0
AND (n.`time` IS NULL OR n.`vehicleNo` IS NULL OR n.`trainWeight` IS NULL);

        QueryWrapper<TbTrackScaleException> queryWrapper = new QueryWrapper<TbTrackScaleException>();
        queryWrapper.eq("isDelete", ConstantUtils.ISDELETE_FALSE)
                .and(wrapper -> wrapper.isNull("time")
                        .or().isNull("trainWeight").or().isNull("vehicleNo"));
