MyBatis-Plus 使用lambda r->r.getId()查询报错

当前使用版本(必填,否则不予处理)

3.4.0

该问题是如何引起的？(确定最新版也有问题再提!!!)

@Test
public void getUsers() {
    LambdaQueryWrapper<MpUser> eq = new QueryWrapper<MpUser>().lambda().eq(r->r.getId(), 2);
    List<MpUser> yu = mpUserMapper.selectList(eq);
    System.out.println(yu);
}

重现步骤(如果有就写完整)

运行上面的代码就报错了，但是写成
LambdaQueryWrapper eq = new QueryWrapper().lambda().eq(MpUser::getId, 2); 就是正常的，不过我习惯写箭头函数

不支持

有没有支持计划呢，感觉这样优雅的写代码会很爽 r->r.getId()>10&&r.getAge<18 转换成id>10 and age<18
