如何在独立代码中创建ResourceResolverFactory？

import org.apache.sling.api.resource.ResourceResolverFactory;
import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.api.resource.LoginException;

public class Example {
  public static void main(String[] args) {
    // 创建配置对象
    Map<String, Object> config = new HashMap<>();
    config.put(ResourceResolverFactory.SUBSERVICE, "myservice");

    // 创建ResourceResolverFactory
    ResourceResolverFactory resolverFactory = // 通过框架获取ResourceResolverFactory实例

    // 使用ResourceResolverFactory创建ResourceResolver
    try (ResourceResolver resourceResolver = resolverFactory.getServiceResourceResolver(null)) {
        // 使用resourceResolver访问和操作资源
        // ...
    } catch (LoginException e) {
        // 处理登录异常
    }
  }
}
