java - Spring Neo4j - 无法访问非托管扩展

Question

我已经部署了 Neo4j 非托管扩展。可以使用 REST 客户端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，它不断抛出 401 Unauthorized。

我使用 Spring RestTemplate 来调用非托管扩展。

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 ogm.properties 中配置的 URI 和凭据。

Components.driver().getConfiguration().getURI();
Components.driver().getConfiguration().getCredentials();
