当前使用版本(必填,否则不予处理)

  <dependency>
      <groupId>com.baomidou</groupId>
      <artifactId>mybatis-plus-boot-starter</artifactId>
      <version>3.4.3</version>
  </dependency>

该问题是如何引起的？(确定最新版也有问题再提!!!)

使用LambdaQueryWrapper传入 lambda表达式式时报错

重现步骤(如果有就写完整)

 // TBasicRoom 为数据库实体
LambdaQueryWrapper<TBasicRoom> queryWrapper = new LambdaQueryWrapper<>();
// 第一种写法
queryWrapper.orderBy(true, true, (TBasicRoom t) -> t.getId());
// 第二种写法
queryWrapper.orderBy(true, true, TBasicRoom::getId);

第一种写法报错，第二种写法正常，报错信息在下面

找到问题原因了：Java中普通lambda表达式和方法引用本质上有什么区别？ - RednaxelaFX的回答 - 知乎 https://www.zhihu.com/question/51491241/answer/126232275
