Question

我正在使用Grails中的Angular项目探索GORM中的动态多租户。目前，我在我的application.yml

中有以下内容

grails:
    gorm:
        multiTenancy:
            mode: DATABASE
            tenantResolverClass: org.grails.datastore.mapping.multitenancy.web.SubDomainTenantResolver
            connectionSourcesClass: org.grails.datastore.mapping.mongo.connections.MongoConnectionSources
            connectionsCollection: "myconnections"
        dataSource:
          dbCreate: create-drop
          url: 'mongodb://root:root@localhost:27017?ssl=false&authSource=admin'

这是我的application.yml

grails:
    gorm:
        multiTenancy:
            mode: DATABASE
            tenantResolverClass: org.grails.datastore.mapping.multitenancy.web.SubDomainTenantResolver
            connectionSourcesClass: org.grails.datastore.mapping.mongo.connections.MongoConnectionSources
            connectionsCollection: "myconnections"
        dataSource:
          dbCreate: create-drop
          url: 'mongodb://root:root@localhost:27017?ssl=false&authSource=admin'

我在build.groovy中添加了以下内容并删除了org.grails.plugins:hibernate5

   compile "org.mongodb:mongodb-driver:3.4.2"
   compile 'org.grails.plugins:mongodb:6.1.2'

根据我是否为我的域类实现MultiTenant接口，在尝试这两件事之后发生了以下事情。

1.如果我实现了界面，那么我会收到以下错误

Caused by: java.lang.IllegalStateException: Either class [com.track.User] is not a domain class or GORM has not been initialized correctly or has already been shutdown. Ensure GORM is loaded and configured correctly before calling any methods on a GORM entity.

如果我没有实现它，那么一切都只是进入我的mongodb服务器上的一个数据库（名为test）。

我错过了什么？

****更新**** 从头开始创建一个新项目后，我收到以下异常

Caused by: org.grails.datastore.mapping.multitenancy.exceptions.TenantNotFoundException: No tenantId found
