我是Neo4j的新手。我正在使用Neo4j 2.2.2和Spring Data在Java中尝试一些应用程序。 我使用spring-data-neo4j（2.2.2.RELEASE）来连接Neo4j DB。我已成功使用Spring Data中的存储库完成所有CRUD操作。 但我无法打开＆amp;在Neo4J UI工具中查看此DB。 当我试图从控制台启动Neo4J服务器时，我收到了错误消息。
emuser1@em02-desktop:~/Installations/neo4j-community-2.2.2/bin$ ./neo4j start

我检查了数据库商店中的message.log文件。它显示在以下例外情况下。

任何人都可以帮助我。我有什么问题吗？
提前致谢。
注意：我的问题与here相同。但是没有令人满意的答案。
答案 0 :(得分：2)
你有一些版本混淆。 Spring Data Neo4j 2.2.2适用于Neo4j 1.9左右。带有Neo4j 2.0的SDN 3.0和仅带有Neo4j 2.2.2的SDN 3.3.1（即将发布）。 SDN 3.3.0适用于Neo4j 2.1.x
这就是为什么它会要求您public void AddNLogConfigurationTypeTagret_WhenCalled_ConsoleTargetsAdded()
{
// Arrange
const int expectedConsoleTargetCount = 2;
var loggerModel = new LoggerModel();
var nLogLoggingConfiguration = new LoggingConfiguration();
var consoleTargetBuilder = new ConsoleTargetBuilder(loggerModel, nLogLoggingConfiguration);
// Act
consoleTargetBuilder.AddNLogConfigurationTypeTagret();
// Assert
Assert.AreEqual<int>(expectedConsoleTargetCount, nLogLoggingConfiguration.AllTargets.Count);
}
中的allow_store_upgrade=true配置设置。
但我建议将您的SDN项目升级到SDN 3.3.0，然后重新导入您的数据并仍然从Neo4j 2.1升级到2.2，但至少您将拥有标签和架构索引。
