或任何Web应用程序服务器。
我在AWS的服务器上站了一台Neo4J主服务器。
我有一个使用Embedded Neo4J的Web应用程序，我希望它与Neo4J服务器集群。
我的设置代码结构如下：
static class ZeusHADatabaseFactory extends HighlyAvailableGraphDatabaseFactory {
public GraphDatabaseService newEmbeddedDatabase(String path) {
System.out.println("New Highly Available Database! " + SystemGlobals.getProperties().getProperty("neo4j.ha.initial_hosts"));
//10.0.0.185:5001
if(graphDB != null){
return graphDB;
}else{
graphDB = super.newEmbeddedDatabaseBuilder(path)
.setConfig(GraphDatabaseSettings.keep_logical_logs, "false")
.setConfig(GraphDatabaseSettings.allow_store_upgrade, "true")
.setConfig("ha.server_id", "2")
.setConfig("ha.inital_hosts", (String)SystemGlobals.getProperties().getProperty("neo4j.ha.initial_hosts"))
.newGraphDatabase();
graphDB.index().getNodeAutoIndexer().setEnabled(true);
graphDB.index().getRelationshipAutoIndexer().setEnabled(true);
registerShutdownHook(graphDB);
return graphDB;
}
}
}
但我得到这样的错误：

我的配置是否正确？
更新：我在我的本地机器上工作（使用Resin Java EE服务器）但是当我在AWS上部署到Tomcat时，我仍然收到相同的错误消息。
