我使用orientdb控制台创建了一个数据库:
create database plocal:/C:/Development/orientdb/databases/testdb root root plocal graph
我启动了服务器以确保我的数据库已成功创建。我打开了 网络界面:
localhost:2480
我使用root
作为用户并使用root
作为密码登录testdb。一切
工作得很好。但是当我现在想要从Java-Code连接到我的数据库时:
OrientGraph graph = null;
try {
graph = new OrientGraph("plocal:C:/Development/orientdb/databases/testdb", "root", "root");
System.out.println("success");
} catch(OException e) {
System.out.println("no success - " + e.getMessage());
e.printStackTrace();
} finally {
if(graph != null) {
graph.shutdown();
}
}
我得到以下异常:
Exception in thread "main" com.orientechnologies.orient.core.exception.OSecurityAccessException: User or password not valid for database: 'testdb'

为什么他告诉我用户名或密码错误?
答案 0 :(得分:5)
在"创建数据库"来自控制台的命令,用户和密码仅用于对远程数据库进行身份验证。使用" plocal"," local"和"记忆"管理员用户的网址始终是" admin"用密码" admin"。
所以使用:
graph = new OrientGraph("plocal:C:/Development/orientdb/databases/testdb", "admin", "admin");
从OrientDB 1.7-SNAPSHOT开始,控制台仅接受此类情况的URL:
create database plocal:/C:/Development/orientdb/databases/testdb
