远程neo4j连接权限被拒绝错误

时间：2016-04-25 14:39:52

标签： neo4j spring-data-neo4j-4 neo4j-ogm

我可以从localhost到达neo4j服务器并成功运行查询，但我无法从远程计算机运行查询。在远程计算机上，我可以从浏览器访问neo4j。 http://x.x.x.x:7474让我进入neo4j网络界面。但是当我从spring执行查询时，它会给出permision denied错误。查询很简单：

User u = new User();
u.setName("test");
session.save(u);

ogm.properties：

driver=org.neo4j.ogm.drivers.http.driver.HttpDriver
URI=http://neo4j:1234@x.x.x.x:7474

完整堆栈跟踪是：

1 个答案:

答案 0 :(得分：1)

我不认为这是'neo4j'问题。这看起来更像防火墙相关的异常，因为java.net.SocketException: Permission denied: connect可能意味着有一个防火墙阻止你对端口7474的请求。是的我知道你可以从你的浏览器连接好但是neo4j / apache HttpClient正在内部打开java.net套接字它被封锁了。其他用户在使用java.net套接字时遇到类似问题，具体取决于防火墙设置，使用的java版本，操作系统版本等等。

尝试使用java.net socket到http://x.x.x.x:7474或使用Apache HttpClient打开直接连接，看看是否仍然得到相同的异常。这应该告诉你spring数据neo4j lib是否是原因。
