Servlets 从servlet中调用时，CQ5 QueryBuilder不返回任何结果

我有一个从SlingAllMethodsServlet扩展而来的servlet，它使用QueryBuilder在存储库中的路径中搜索图像。当我执行servlet时，QueryBuilder返回0个结果，但是当我从CQ提供的querydebug.html运行相同的查询时，它返回预期的结果

我已将com.day.cq.search的日志级别设置为DEBUG，以尝试查找我的错误，但我在记录器中看到两次查询尝试的输出相同，只是servlet请求返回0个结果。以下是servlet调用的日志输出：

下面是querydebug.html的输出：

以下是在servlet中运行查询的代码：

        Map<String,String> parms = new HashMap<String,String>();

        parms.put("type", "dam:Asset" );
        parms.put( "path", "/content/dam/nhhc/our-collections/photography" );
        // This search is only for low-res images so use the DPI value to keep from returning high-res images
        parms.put( "property", "jcr:content/metadata/dam:Physicalheightindpi" );
        parms.put(  "property.value", "96" );
        if( nodeName != null && !nodeName.isEmpty() ) {
            parms.put(  "nodename", nodeName );
        }

        Query query = builder.createQuery( PredicateGroup.create( parms ), session );

从日志中可以看到，servlet和querydebug运行的查询是相同的，所以我不知道为什么从servlet运行时没有得到任何结果。如果您有任何建议或建议，我们将不胜感激。

我认为这不是代码的问题。这可能与用户权限有关。我猜您是通过querydebug.html以admin的身份执行查询，而在servlet中，会话是由不同的用户执行的，或者不是由admin执行的。问题确实是权限问题。我使用了resolverFactory.getResourceResolver，而不是resolverFactory.GetAdministrativeSolver。一旦我改变主意，问题就解决了。谢谢你的提示！
