生成简单的依赖注入实现IOC框架代码

好的，以下是一个简单的依赖注入实现IOC框架代码示例：

public interface MyService {
    void doSomething();
}

public class MyServiceImpl implements MyService {
    @Override
    public void doSomething() {
        System.out.println("MyServiceImpl do something.");
    }
}

public class MyController {
    private MyService myService;
    
    public void setMyService(MyService myService) {
        this.myService = myService;
    }

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

public class MyContainer {
    private Map<Class, Object> beans = new HashMap<>();
    
    public <T> T getBean(Class<T> clazz) throws Exception {
        T bean = (T) beans.get(clazz);
        if (bean == null) {
            bean = clazz.newInstance();
            beans.put(clazz, bean);
            injectDependency(bean);
        }
        return bean;
    }

    private void injectDependency(Object bean) throws Exception {
        Field[] fields = bean.getClass().getDeclaredFields();
        for (Field field : fields) {
            if (field.isAnnotationPresent(Autowired.class)) {
                Object injectBean = getBean(field.getType());
                field.setAccessible(true);
                field.set(bean, injectBean);
            }
        }
    }
}

public class Main {
    public static void main(String[] args) throws Exception {
        MyContainer container = new MyContainer();
        container.getBean(MyController.class).doSomething();
    }
}

请问您还有其他问题吗？或者您需要我解释上面的代码吗？
