尝试phantom-dsl
按照本教程在 cassandra 中创建用于单元测试的模式:
http://outworkers.com/blog/post/phantom-tips-3-understanding-phantom-connectors
我在尝试自动生成架构时遇到了这个问题
[ERROR] /home/.../test/BaseCassandraSpec.scala:54: error: not enough arguments for method autocreate: (keySpace: com.websudos.phantom.connectors.KeySpace)
com.websudos.phantom.builder.query.CreateQuery.Default[com.neruti.db.models.ConcreteUserModel,com.neruti.User].
[ERROR] Unspecified value parameter keySpace.
[ERROR] Await.result(database.userModel.autocreate().future(),10.seconds)
有什么建议吗?
当前使用版本1.29.6
BaseCassandraSpec
import com.neruti.User
import com.neruti.db.models._
import com.neruti.db.databases._
import com.neruti.db.services._
import com.neruti.db.Connector._

import scala.concurrent.ExecutionContext.Implicits.global
override protected def beforeAll(): Unit = {
Await.result(database.userModel.autocreate().future(),10.seconds)
}
数据库
class UserDatabase (val connector: KeySpaceDef){
object userModel extends ConcreteUserModel with connector.Connector
}
object ProductionDb extends UserDatabase(connector)
trait ProductionDatabaseProvider {
def database: UserDatabase
}
trait ProductionDatabase extends ProductionDatabaseProvider {
override val database = ProductionDb
}
object testDB extends UserDatabase(testConnector)
trait testDatabaseProvider {
def database: UserDatabase
}
trait testDatabase extends testDatabaseProvider{
override val database = testDB
}
连接器
package com.neruti.db
import com.neruti.db.models._
import com.websudos.phantom.database.Database
import com.websudos.phantom.connectors.ContactPoints
import com.websudos.phantom.dsl.KeySpaceDef
object Connector {
// TODO: these key value pairs shld get from HOCON config file
val host= Seq("127.0.0.1")
val port = 9042
val keySpace: String = "nrt_entities"
// val inet = InetAddress.getByName
lazy val connector = ContactPoints(host,port).withClusterBuilder(
_.withCredentials("dev", "nrtDev1989")
).keySpace(keySpace)
// embedded cassandra is not supported anymore. Check phantom-sbt.
// lazy val testConnector: KeySpaceDef = ContactPoint.embedded.keySpace(keySpace)
lazy val testConnector: KeySpaceDef = ContactPoints(host,port).noHeartbeat().keySpace(keySpace)
}
