摘要

尝试使用origindb GraphFactory message: GraphFactory could not find [org.apache.tinkerpop.gremlin.orientdb.OrientEmbeddedFactory]错误启动gremlin服务器时

详细

我使用以下配置

Gremlin：apache-tinkerpop-gremlin-server-3.3.1

Orientdb：orientdb-tp3-3.0.2

下载jar文件使用bin/gremlin-server.sh -i com.orientechnologies orientdb-gremlin 3.0.2

gremlinpython：3.3.0

gremlin-server-orientdb.yaml file

也尝试过这个

gremlin.graph=org.apache.tinkerpop.gremlin.orientdb.OrientGraph

您正在混合使用许多不同的版本，因此很难说出什么可行。首先，TinkerPop建议您尝试将服务器的版本与客户端的版本进行匹配。因此，这意味着如果您在服务器上使用3.3.1，则应尝试使用客户端的3.3.1（在您的情况下为gremlin-python）。接下来，您将Orientdb-gremlin与3.0.2似乎已绑定到TinkerPop 3.3.0，

https://github.com/orientechnologies/orientdb-gremlin/blob/3.0.2/driver/pom.xml

这意味着为了获得最佳结果，您可能应该在Gremlin Server和gremlin-python上使用3.3.0。现在，尽管我提到了有关“匹配版本”的所有内容，但我会说可以混合使用版本，但是匹配将有助于限制刚开始使用时可能出错的地方，所以我鼓励您从此处开始

对于您的错误，我认为您安装了错误的依赖项。您应该已经完成：

bin/gremlin-server.sh -i com.orientechnologies orientdb-gremlin-server 3.0.2

与orientdb-gremlin-server一样会带来OrientEmbeddedFactory和orientdb-gremlin依赖项。我还认为您的orientdb-empty.properties文件缺少一些配置选项-查看默认值和未设置的here。

GraphFactory无法找到gremlin.graph属性configration
