我刚开始使用neo4j。当我想连接到Windows上的现有数据库时，一切正常，我的应用程序找到db并运行我的业务，但在Linux中我捕获Error starting org.neo4j.kernel.impl.factory.CommunityFacadeFactory, /opt/neo4j-community-3.0.0-M04/data/databases/graph.db异常。
我使用的是2.3.3版本
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j</artifactId>
<version>2.3.3</version>
</dependency>
我的代码：
GraphDatabaseService graphDb = null;
try {
// graphDb = new GraphDatabaseFactory().newEmbeddedDatabase("/opt/neo4j-community-3.0.0-M04/data/databases/graph.db");
graphDb = new GraphDatabaseFactory().newEmbeddedDatabaseBuilder(new File("/opt/neo4j-community-3.0.0-M04/data/databases/graph.db")).
setConfig("org.neo4j.server.database.location", "/opt/neo4j-community-3.0.0-M04/data/databases/graph.db").
setConfig("allow_store_upgrade","true").
// loadPropertiesFromFile("/opt/neo4j-community-3.0.0-M04/conf/neo4j.conf").
newGraphDatabase();
} catch (Exception e) {
System.out.println("e = " + e.getMessage());
e.printStackTrace();
}
registerShutdownHook(graphDb);
如何连接到linux中的现有数据库。 谢谢。
添加stacktrace
