java - 如何从资源解析器工厂获取会话对象？

Question

@Component
public class AddNode {
    @Reference
    static ResourceResolverFactory resolverFactory;
    static Session session;

    public static void main(String[] args) throws Exception { 


        ResourceResolver resourceResolver = resolverFactory.getServiceResourceResolver(null);

        session = resourceResolver.adaptTo(Session.class);        
          Node root = session.getRootNode(); 

          Node adobe = root.addNode("ProgramNode"); 
          Node day = adobe.addNode("subnode"); 
          day.setProperty("jcr:title", "programNode"); 

          Node node = root.getNode("ProgramNode/subnode"); 
          System.out.println(node.getPath()); 
          System.out.println(node.getProperty("jcr:title").getString()); 
          session.save(); 
          session.logout();


        }

}

这里 resolverFactory.getServiceResourceResolver(null); 我需要在 null 处传递任何参数。请举一些例子来访问存储库。

Answer 1

查看 ResourceResolverFactory 的文档。

https://sling.apache.org/apidocs/sling7/org/apache/sling/api/resource/ResourceResolverFactory.html

Answer 2

通过工厂访问时，我们应该使用系统用户访问存储库。你需要

1. 创建系统用户，提供适当的权限
2. 将捆绑符号名称映射到系统用户

3. 使用系统用户通过ResourceResolverFactory

   Map<String, Object> param = new HashMap<String, Object>();
   param.put(ResourceResolverFactory.SUBSERVICE, "<sub-service-name>");
   ResourceResolver resolver = null;         
   resolver = resolverFactory.getServiceResourceResolver(param);
   session = resolver.adaptTo(Session.class);
