java - 使用 Neo4j 的休眠 OGM - 与服务器的应用程序连接失败

问题描述

我正在尝试使用休眠 ogm 连接到我在本地机器上使用 docker 运行的 neo4j 服务器。

当我尝试连接时，我收到了消息：

如果尝试使用 neo4j 桌面使用相同的身份验证和 url 数据连接到服务器，我会成功。

我真的不明白为什么这不起作用。

完整代码在 github 上的这个链接中：https ://github.com/AndreLuis117/ondm-frameworks-experiment/tree/master/hibernateOGM/neo4j_hibernateOGM

如果有人想查看依赖项。

我使用的创建 docker 容器的脚本是：

docker run `
--name testneo4j `
-p7474:7474 -p7687:7687 `
-d `
-v $HOME/neo4j/data:/data `
-v $HOME/neo4j/logs:/logs `
-v $HOME/neo4j/import:/var/lib/neo4j/import `
-v $HOME/neo4j/plugins:/plugins `
--env NEO4J_AUTH=neo4j/test `
--env NEO4J_dbms_connector_https_advertised__address="localhost:7473" `
--env NEO4J_dbms_connector_http_advertised__address="localhost:7474" `
--env NEO4J_dbms_connector_bolt_advertised__address="localhost:7687" `
neo4j:latest

有人可以帮帮我吗？这里有没有人设法使用远程服务器使用 neo4j 实现休眠 ogm？有人有这个实现的例子吗？

解决方案

在撰写本文时，Hibernate OGM 仅与 Neo4j 3.x 兼容。

Neo4j 3.5 是长期支持版本，因此您应该能够启动 3.5.x Docker 容器并使用您的应用程序连接到它。
