启用非托管扩展配置后，Neo4J服务器启动错误 [英] Neo4J server startup error after enabling the unmanaged extension configuration

问题描述

我在Windows OS 10上使用Neo4J社区版2.3.0.一切正常，直到我将 neo4j-server.properties 文件的配置更改为:

I am using Neo4J community edition 2.3.0 on windows OS 10. Everything works well until I changed the configuration at neo4j-server.properties files as:

 org.neo4j.server.thirdparty_jaxrs_classes=org.neo4j.examples.server.unmanaged=/examples/unmanaged

服务器启动时的错误是:

The error at server startup is:

启动Neo4j失败:org.neo4j.server.web.NeoServletContainer-5b85e832 @ 73766070 == org.neo4j.server.web.NeoServletContainer，-1，false

Starting Neo4j failed: org.neo4j.server.web.NeoServletContainer-5b85e832@73766070==org.neo4j.server.web.NeoServletContainer,-1,false

如果我禁用此更改，则服务器启动会很好.我正在尝试针对Neo4J教程给出的非托管扩展运行HelloWorld示例，并按照所有说明进行操作.

If I disable this change then server starts very well. I am trying to run the HelloWorld example for the unmanaged extension as given with the Neo4J tutorial and follow all the instructions.

用于构建Jar的Java编译器是1.7，我正在使用STS工具.

The Java compiler used to build the Jar is 1.7 and I am working on STS tool.

及早做出反应会有所帮助.

An early response would be helpful.

推荐答案

问题是您使用的.jar没有所需的.jars

The problem is that the .jar you are using does not have the required .jars

尝试将您的jar导出为可执行jar(我是从Eclipse导出的)，并选中将所需的库打包到生成的JAR中"选项

Try exporting the your jar as an executable jar (I did it from Eclipse) and check the option "Package required libraries into generated JAR"
