如何扩展使用直接注入的类？

// 原始类
public class OriginalClass {
    private Dependency dependency;

    public OriginalClass(Dependency dependency) {
        this.dependency = dependency;
    }

    public void doSomething() {
        // 使用依赖的功能
        dependency.doSomething();
    }
}

// 扩展类
public class ExtendedClass extends OriginalClass {
    private AdditionalDependency additionalDependency;

    public ExtendedClass(Dependency dependency, AdditionalDependency additionalDependency) {
        super(dependency);
        this.additionalDependency = additionalDependency;
    }

    @Override
    public void doSomething() {
        // 执行原始类的功能
        super.doSomething();

        // 执行额外的功能
        additionalDependency.doSomethingElse();
    }
}

// 使用扩展类
public class Main {
    public static void main(String[] args) {
        Dependency dependency = new Dependency();
        AdditionalDependency additionalDependency = new AdditionalDependency();

        ExtendedClass extendedClass = new ExtendedClass(dependency, additionalDependency);
        extendedClass.doSomething();
    }
}
