在 Java 中使用高阶函数实现依赖注入的优点是什么？

import java.util.function.Function;

class Service {
    private Dependency dependency;

    // 使用高阶函数进行构造函数注入
    public Service(Function<Service, Dependency> dependencyFactory) {
        this.dependency = dependencyFactory.apply(this);
    }

    public void doSomething() {
        dependency.doSomething();
    }
}

// 定义依赖项接口
interface Dependency {
    void doSomething();
}

// 实现依赖项
class RealDependency implements Dependency {
    @Override
    public void doSomething() {
        System.out.println("Doing something...");
    }
}

public class Main {
    public static void main(String[] args) {
        // 使用匿名内部类创建服务
        Service service = new Service(new Function<Service, Dependency>() {
            @Override
            public Dependency apply(Service service) {
                return new RealDependency();
            }
        });

        service.doSomething();
    }
}
