Question

我正在通过docker-compose文件使用OrientDB。我已经使用ETL加载器工具导入了数据，并在Meetup数据库中创建了Event类。我可以通过OrientDB控制台查看此类的数据。我试图使用Scala API读取数据。但是，我收到一个错误，找不到我的Event类：

OQueryParsingException: Error on parsing query at position #6: Error on parsing query
Query:  Event LIMIT 10
OCommandExecutionException: Class 'EVENT' was not found in database 'Meetup'

这是我用来连接数据库的代码：

    val uri = "plocal:databases/Meetup"
    val factory = new OrientGraphFactory(uri, "user", "password")
    val graph = factory.getTx
    graph.command(new OCommandSQL("select * from Event limit 10"))
  .execute()

当我在控制台中运行相同的查询时，我将获得事件表的必需行：

docker exec -it orientdb_container /orientdb/bin/console.sh

orientdb> connect plocal:databases/Meetup user password

Connecting to database [plocal:databases/Meetup] with user 'admin'...OK
orientdb {db=Meetup}>SELECT * FROM Event LIMIT 10

如何解决此错误？这是代码还是配置错误？

Docker-compose文件如下：

orientdb:
  image: orientdb:latest
  ports:
    - "2424:2424"
    - "2480:2480"
  environment:
    ORIENTDB_ROOT_PASSWORD: 'password'
  volumes:
    - /orientdb/config:/orientdb/config
    - /orientdb/databases:/orientdb/databases
    - /orientdb/backup:/orientdb/backup
    - ./import_json:/orientdb/bin/import_json
    - ./dataset_csv:/orientdb/bin/dataset_csv

在数据库OrientDB Scala API中找不到类
