ubuntu - 在 ubuntu 上本地运行 Neo4J

Question

我想得到这个neo4j project (sdn)在 ubuntu 上本地运行。基于instructions .我做了以下事情:

使用 guide 在 ubuntu 上安装了 neoj4

设置用户并传递给 neo4j/neopass 在网络用户界面中:http://localhost:7474/browser/

已添加 export GRAPHENEDB_URL="http://neo4j:neopass@localhost:7474"给我的 ~/.bashrc 文件。

执行:neo4j-shell -c < categorySetup.cql

使用以下命令启动 Web 应用程序:mvn clean spring-boot:run

但是当我在 http://localhost:8080/ 访问它时我只是得到空的下拉菜单。这是终端中的输出:

2016-07-16 18:10:06,611 ERROR 4j.ogm.session.response.RowModelResponse:  47 - failed to parse: {"row":[[{"name":"Bacon"},{},{"categoryColor":"#FF0000","name":"Meat"}]],"meta":[[{"id":8,"type":"node","deleted":false},{"id":0,"type":"relationship","deleted":false},{"id":1,"type":"node","deleted":false}]]}

基于以下，我尝试在 sdn-4.1 上构建 + 运行测试( mvn clean install )但由于缺少依赖项而失败:

[ERROR] Failed to execute goal on project flavorwocky: Could not resolve dependencies for project com.flavorwocky:flavorwocky:jar:2.0-SNAPSHOT: The following artifacts could not be resolved: org.springframework.data:spring-data-commons:jar:1.12.0.M1, org.springframework.data:spring-data-neo4j:jar:4.1.0.M1, org.springframework.data:spring-data-neo4j:jar:tests:4.1.0.M1: Failure to find org.springframework.data:spring-data-commons:jar:1.12.0.M1 in

我尝试使用最新发布的版本，但是在运行测试时出现了一堆类未找到错误:

java.lang.NoClassDefFoundError: org/neo4j/ogm/service/ResourceService

似乎 sdn-4.1与 sdn 相比已损坏构建良好 +所有测试运行，所以现在我将尝试让项目在 sdn 上运行

Answer 1

你可以有一个本地的 neo4j，指定你第一次启动 neo4j 时使用的密码，或者禁用 auth 来播放。

您最好使用 sdn-4.1分支，实际上是 sdn分支有一些问题，一年以来没有维护。

其次，没有/categories端点，右端点是/api/categories在运行 cql 后，由 Angular 应用程序使用并返回一些 json脚本我有以下响应:

[{"@id":"1","name":"Eggs and Dairy","categoryColor":"#D6C2AD","id":7864},{"@id":"2","name":"Meat","categoryColor":"#FF0000","id":7865},{"@id":"3","name":"Vegetable","categoryColor":"#009933","id":7866},{"@id":"4","name":"Seafood","categoryColor":"#0000CC","id":7867},{"@id":"5","name":"Fruit","categoryColor":"#FF9900","id":7868},{"@id":"6","name":"Nuts and Grains","categoryColor":"#993333","id":7869},{"@id":"7","name":"Herbs and Spices","categoryColor":"#FFF2BA","id":7870},{"@id":"8","name":"Condiments","categoryColor":"#CC66FF","id":7871}]
