import org.apache.sling.models.annotations.injectorspecific.SlingObject;

@Model(adaptables = Resource.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public class PagePropertiesModel {

    @SlingObject
    private Resource resource;

    public String getTitle() {
        return resource.getValueMap().get("jcr:title", String.class);
    }

    // 其他属性的访问方法
}

<sly data-sly-use.pageProperties="com.example.models.PagePropertiesModel">
