我从 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。我打开网页界面:

localhost:2480

我使用root用户和root密码登录到 testdb。一切正常。但是当我现在想从 Java 代码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'
at com.orientechnologies.orient.core.metadata.security.OSecurityShared.authenticate(OSecurityShared.java:150)

at de.hof.iisys.relationExtraction.freebase.tinkerpop.DAO.openGraph(DAO.java:30)
at de.hof.iisys.relationExtraction.freebase.main.Main.main(Main.java:44)

为什么他告诉我用户名或密码是错误的而不是错误的?

在控制台的“create database”命令中,用户和密码仅用于对远程数据库进行身份验证。对于“plocal”、“local”和“memory” URL,管理员用户始终是“admin”,密码为“admin”。

所以使用:

graph = new OrientGraph("plocal:C:/Development/orientdb/databases/testdb", "admin", "admin");

从 OrientDB 1.7-SNAPSHOT 开始,控制台只接受这种情况下的 URL:

create database plocal:/C:/Development/orientdb/databases/testdb
