通過java代碼生成db后，Neo4j 2.2.2服務器無法啟動

Question

我是Neo4j的新手。 我正在使用Neo4j 2.2.2和Spring Data在Java中嘗試一些應用程序。 我使用spring-data-neo4j（2.2.2.RELEASE）來連接Neo4j DB。 我已成功使用Spring Data中的存儲庫完成所有CRUD操作。 但是我無法在Neo4J UI工具中打開和查看此數據庫。 當我試圖從控制台啟動Neo4J服務器時，我收到波紋管錯誤消息。

emuser1@em02-desktop:~/Installations/neo4j-community-2.2.2/bin$ ./neo4j start
WARNING: Max 1024 open files allowed, minimum of 40 000 recommended. See the Neo4j manual.
Starting Neo4j Server...WARNING: not changing user
process [14509]... waiting for server to be ready.. Failed to start within 120 seconds.
Neo4j Server may have failed to start, please check the logs.

我檢查了數據庫存儲中的message.log文件。 它顯示在以下例外情況下。

誰能幫幫我嗎。 有什么我做錯了嗎？

提前致謝。

注：我有同樣的問題在這里 。 但是沒有令人滿意的答案。

Answer 1

你有一些版本混亂。 Spring Data Neo4j 2.2.2適用於Neo4j 1.9左右。 帶有Neo4j 2.0的SDN 3.0和僅帶有Neo4j 2.2.2的SDN 3.3.1（即將發布）。 SDN 3.3.0適用於Neo4j 2.1.x.

這就是它要求你在conf/neo4j.properties設置allow_store_upgrade=true配置的conf/neo4j.properties 。

但我建議將您的SDN項目升級到SDN 3.3.0，然后重新導入您的數據並仍然從Neo4j 2.1升級到2.2，但至少您將擁有標簽和架構索引。
