Question

使用spring mvc创建了一个google app引擎应用程序，现在我们正在运行它本地devAppServer：appengine：devserver，用于访问apache的这个应用程序 solr服务器（通过http://xx.xxx.xx.xxx/solr)its运行AWS EC2 istance，

编写了一个像

这样的控制器

String apacheUrl = "http://xx.xxx.xx.xxx/solr";
SolrServer solr = new HttpSolrServer(apacheUrl);
ModifiableSolrParams parameters = new ModifiableSolrParams();
      parameters.set("q", "*:*"); //query everything thanks to user1452132!         
      parameters.set("fl", "id,propertyName");//send back just the id values
      parameters.set("fq", "cityName:\""+cityName+"\"");//Id like this in json format please

无法从apache solr获取结果，

1）无论如何写控制器 3）谷歌应用引擎所需的任何权限访问

任何建议

无法从部署在Google App引擎上的应用程序访问apache solr服务
