在TypeScript中按类型名称实例化抽象派生类

abstract class AbstractClass {
  abstract method(): void;
  abstract property: string;
}

class DerivedClass extends AbstractClass {
  method(): void {
    console.log("DerivedClass method");
  }

  property: string = "DerivedClass property";
}

function createInstance(className: string): AbstractClass {
  const classConstructor = (global as any)[className];
  if (typeof classConstructor === "function") {
    return new classConstructor();
  } else {
    throw new Error(`Class ${className} not found`);
  }
}

const instance = createInstance("DerivedClass");
instance.method(); // 输出：DerivedClass method
console.log(instance.property); // 输出：DerivedClass property
