报错：There is no getter for property named 'distinct' in

原因分析：

selectByExample()方法传递的参数错误，应该传example类型，而不是实体类。

错误代码如下:

@Override
    public PlantGrow selectPlantGrow(PlantGrow plantGrow1) {
        List<PlantGrow> plantGrows = plantGrowMapper.selectByExample(plantGrow1);
        if (!CollectionUtils.isEmpty(plantGrows)) {
            return plantGrows.get(0);
        }
        return null;
    }

解决：改为select
