Question

我想在NEO4j中创建一个服务器插件，为此我创建了一个包名为dummy.test.neo4j.NodeExploration.exploring的插件。我已在META-INF.services中注册了此插件，但是当我在NEO4j.conf文件中添加此包的引用为

dbms.unmanaged_extension_classes=dummy.test.neo4j.NodeExploration=/dummy/exploring

我收到以下错误。

我想我不确定我是否在NEO4j.conf文件中添加了正确的引用

Answer 1

当我们同时考虑服务器插件和非托管扩展概念时，会导致上述异常。因为我刚删除了行

dbms.unmanaged_extension_classes=dummy.test.neo4j.NodeExploration=/dummy/exploring

来自neo4j.conf的

，只需在http://localhost:7474/db/data/ext/exploring/graphdb/exploring

上调用post get请求

探索是我的类和函数名称

在NEO4j中添加非托管扩展
