我已经部署了Neo4j非托管扩展。可以使用REST Client调用非托管扩展，并成功返回结果。问题是，当我尝试从另一个Java类调用/调用非托管扩展时，它会不断抛出401 Unauthorized。
我用Spring RestTemplate调用了非托管扩展。
我的代码：
RestTemplate restTemplate = new RestTemplate();
PostPhotoRest postPhotoRest = restTemplate.getForObject("http://myneo4jusername:myneo4jpassword@localhost:7474/extension/servicetwo/postphoto/55b12d35-94fd-4297-bb18-e6040d7b7109", PostPhotoRest.class);
完全错误：

驱动程序配置可以提供在ogm.properties中配置的URI和凭据。
Components.driver().getConfiguration().getURI();
Components.driver().getConfiguration().getCredentials();
