Question

我在Neo4j中比较新。新版neo4j插件已发布：http://grails.org/plugin/neo4j。

我在开发环境中运行neo4j V2.0.2。

当我运行其中一个集成测试或启动应用程序时，我收到以下错误：

Error 2014-05-05 01:04:17,828 [localhost-startStop-1] ERROR context.GrailsContextLoader  - Error initializing the application: cannot handle type rest

这是我的BuildConfig.groovy：

        //runtime ":cached-resources:1.1"
        //runtime ":yui-minify-resources:0.1.5"
    }
}

我正在按如下方式配置数据存储区：

grails {    
        neo4j {
            type = "rest"
            location = "http://localhost:7474/db/data/"
        }
}

我错过了什么？我现在几个小时都找不到相关或类似的东西......

提前谢谢。

该插件的2.0.0-M01版本尚不支持远程Neo4j实例。它只支持嵌入式。我的计划是在里程碑2中增加对休息的支持。

在grails应用程序中使用neo4j插件使用'rest'类型的问题
