我是Neo4j的新手。我正在使用Neo4j 2.2.2和Spring Data一起在Java中嘗試一些應用程序。 我正在使用spring-data-neo4j（2.2.2.RELEASE）來連接Neo4j DB。我已經成功完成了在Spring Data中使用存儲庫的所有CRUD操作。 但我無法在Neo4J UI工具中打開&查看此數據庫。 當我試圖從控制檯啓動Neo4J服務器時，出現了以下錯誤消息。Neo4j 2.2.2通過java代碼生成db後服務器無法啓動
[email protected]:~/Installations/neo4j-community-2.2.2/bin$ ./neo4j start

我檢查了我的數據庫商店中的message.log文件。它顯示在下面的例外。

任何人都可以請幫助我。有什麼我做錯了嗎？
在此先感謝。
注：我有和here一樣的問題。但沒有令人滿意的答案。
非常感謝Michael。您能否請我幫我一個忙，建議從哪裏獲得SDN相關信息的資源以供進一步開發。 –
爲了澄清，您的意思是*不*升級到Neo4j 2.2，因爲直到SDN 3.3.1才支持它，對嗎？ –
