对于Kotlin类型的Entity，好像没法使用

val dList = deviceService.baseMapper.selectJoinList(
            DeviceInfo::class.java, MPJLambdaWrapper<Device>()
                .selectAll(DeviceInfo::class.java)
                .leftJoin(DeviceInfo::class.java, DeviceInfo::deviceNo, Device::deviceNo)
                .eq(Device::ownerId, owner.id)
        )

error

该方法仅能传入 lambda 表达式产生的合成类
