mybatis-plus出错：Invalid bound statement (not found): com.kuang.mapper.UserMapper.selectList

错误点：

原因：UserMapper继承BaseMapper，让我们看看BaseMapper

可以发现，BaseMapper使用的是范型。所以上边我们UserMapper继承的BaseMapper也要写上对应的范型。

经过修改：

获得正确结果：

[User(id=1, name=Jone, age=18, email=test1@baomidou.com), User(id=2, name=Jack, age=20, email=test2@baomidou.com), User(id=3, name=Tom, age=28, email=test3@baomidou.com), User(id=4, name=Sandy, age=21, email=test4@baomidou.com), User(id=5, name=Billie, age=24, email=test5@baomidou.com)]
