问题

以下是翻译好的内容：

在超类中，我有一个通用方法。我想根据子类中的实体类型来重写它。这些代码是用Groovy语言编写的。

protected T fromEntity(E entity) {
    return entity
}

我想在子类中重写这个方法。这应该是要重写的方法之一：

@Override
protected FactorInfo fromEntity(Factor f) {
    // 从f中提取并返回FactorInfo
    return new FactorInfo()
}

但是我的IDE显示：

方法未覆盖其超类中的方法。

为什么这个方法没有覆盖超类方法？

英文翻译

I have a generic method in the super class. I want to override this based on entity type in subclasses. These codes are written in groovy language.

 protected T fromEntity(E entity) {
     return entity
 }

I want to override this method in my subclass. This is supposed to be one of the overridden methods:

@Override
protected FactorInfo fromEntity(Factor f) {
    // extract and return FactorInfo from f
    return new FactorInfo()
}

But my IDE says:

> Method does not override method from its super class.

Why this method doesn't override the super method?

子类方法未覆盖其超类通用方法。
