在Neo4j桌面社区版2.3.0上没有加载Spatial扩展/插件

Question

安装Spatial插件并反复重复后，我仍然无法让Neo4j加载扩展程序。

我将Neo4j Community Edition 2.3.0与neo4j-spatial-0.15-neo4j-2.3.0

一起使用

从命令行开始：

$:~ levi$ java -jar ./databases/Neo4j\ Community\ Edition\ 2.3.0.app/Contents/Resources/app/bin/neo4j-desktop-2.3.0.jar

2016-01-25 14:05:17.803-0600 INFO  [o.n.s.CommunityNeoServer] Remote interface ready and available at http://localhost:7474/

并使用curl：

curl -v http://neo4j:password@localhost:7474/db/data/

Answer 1

我对你用来启动Neo4j的方法感到有些困惑。看起来您正在使用Neo4j桌面应用程序，但是从命令行启动它？您是否尝试从桌面应用程序启动？

此外，目录结构可能有点偏。您希望空间扩展jar（以及所有依赖项jar）位于plugins目录的根目录中。如果您点击＆＃34;选项＆＃34;在桌面应用程序中，您将看到插件的默认目录，可以进行配置：

Answer 2

我设法通过从源代码构建来实现这一目标。

$ brew install maven

特别克隆的0.15-neo4j-2.3分支。

编译/安装使用： $ mvn install

将名为neo4j-spatial-0.15-neo4j-2.3.1-server-plugin的目录直接复制到neo4j/plugins目录。

启动服务器然后： $ curl -v http://neo4j:password@127.0.0.1:7474/db/data/
