我下载了apoc-3.1.0.3-all.jar并将其放入我的windows7 Neo4J 3.1.1系统的插件中。
C:\Users>java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
在计算机上杀死了Neo4J进程,然后重新安装了服务器。
我只看到列出了一个apoc程序,其他人给出了关于缺少程序的错误。 neo4j日志中没有错误的迹象。我尝试解锁jar,然后重新启动服务器。没有运气。
我做
没问题Call db.schema()
但有些简单:
CALL apoc.help("help")
将导致
There is no procedure with the name `apoc.help` registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.
我做错了什么,我认为一定是我!)
$call dbms.procedures
apoc.schema.assert apoc.schema.assert(indexes :: MAP?, constraints :: MAP?) :: (label :: STRING?, key :: LIST? OF STRING?, unique :: BOOLEAN?, action :: STRING?) (empty)
db.awaitIndex db.awaitIndex(index :: STRING?, timeOutSeconds = 300 :: INTEGER?) :: VOID Wait for an index to come online (for example: CALL db.awaitIndex(":Person(name)")).

使用安装程序(最常见)安装neo4j与使用zip或tar文件安装neo4j之间的差异很小。
(A)使用安装程序安装neo4j时,安装程序会配置neo4j服务器以查找数据库文件夹中的plugins
文件夹(即,在default.graphdb
文件夹下。
(B)当您从zip或tar文件安装neo4j时,neo4j服务器将在neo4j安装文件夹中查找plugins
文件夹(例如,plugins
文件夹应为neo4j bin
文件夹的兄弟姐妹。)
听起来像(A)适用于你。
答案 1 :(得分:3)
根据我的记忆,你必须在graph.db目录中创建一个plugins
目录,放入apoc jar,然后重新启动服务器。
否则,您可以在dbms.directories.plugins
文件中指定neo4j.conf
。

问题是你使用windows安装程序neo4j,这似乎不适用于插件。所以你必须使用正常工作的neo4j二进制文件。
这意味着您必须下载Windows安装的zip版本并按照此处的说明进行操作:

@cybersam和@logisima的答案是绝对正确的。但是,由于我使用的是Red Hat Linux特别是Oracle-7,因此我还必须为其添加一个附加步骤。这就是我的工作方式
apoc-<version>.jar
下载到/var/lib/neo4j/plugins
目录chown neo4j:neo4j apoc-<version>.jar
chmod 755 apoc-<version>.jar
/etc/neo4j/neo4j.conf
处的neo4j.conf并将行#dbms.security.procedures.whitelist=apoc.coll.*,apoc.load.*
替换为dbms.security.procedures.whitelist=apoc.coll.*,apoc.load.*,apoc.*
并保存。systemctl restart neo4j
注意:确保您下载了正确版本的apoc jar。我正在使用neo4j version 3.5.5
,而我正在使用的apoc jar版本是apoc-3.5.0.3-all.jar
。 Alos确保您在dbms.directories.plugins=/var/lib/neo4j/plugins
/etc/neo4j/neo4j.conf
