我正在使用 Spring 和 Neo4j 制作应用程序，但每当我尝试启动该应用程序时，我都会收到此错误。我确信没有其他程序正在运行。这是错误

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'graphDatabaseService': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.neo4j.kernel.EmbeddedGraphDatabase]: Constructor threw exception; nested exception is java.lang.IllegalStateException: Unable to lock store [C:\Users\Anthony\Documents\tomcat7\apache-tomcat-7.0.40\bin\target\config-test\neostore], this is usually a result of some other Neo4j kernel running using the same store.

Spring 正在尝试在启动期间初始化 GraphDatabaseService。C:\Users\Anthony\Documents\tomcat7\apache-tomcat-7.0.40\bin\target\config-test\neostore是配置的默认位置。将 neo4j db 放在 tomcat 文件夹结构之外的目录中是有意义的。我建议您找到正在初始化 GDB 的 spring 配置文件并将其更改为如下所示

<neo4j:config storeDirectory="C:\home\neo4j-db"/>

正如异常所说，这通常在 Neo4j 的另一个实例使用同一个商店时抛出。通过构造，您不能拥有多个。因此，要么您有另一个进程正在使用该商店，要么您的商店在崩溃（或意外关闭）后可能仍处于锁定状态。

如果您确定没有其他进程正在访问商店，请在启动应用程序之前尝试手动删除 NEO4j_HOME/data/graph.db/lock 和 NEO4j_HOME/data/graph.db/store_lock 文件。
