Question

我刚刚开始使用play，我修改了我正在进行SQL读取的方式，现在我收到以下错误：

[Exception: DB plugin is not registered.]

我这节课的代码是：

package models

import play.api.db._
import play.api.Play.current

import anorm._

case class Housing(id: Long, rent: String, address: String, street0: String, street1: String, neighbourhood: String)

object Housing {

  def all(): List[Housing] = DB.withConnection { implicit c =>
    SQL("select * from housing")().map { row =>
      Housing(row[Long]("id"), row[String]("rent"), row[String]("address"), row[String]("street0"),
        row[String]("street1"), row[String]("neighbourhood"))
    }.toList
  }

  def create(rent: String, address: String, street0: String, street1: String, neighbourhood: String) {}

  def delete(id: Long) {}

}

我不确定这是否是最好的方法，但使用〜链似乎我最终会复制一堆东西。

Answer 1

在application.conf中以某种方式证明了这一行：

dbplugin=disabled

出现了。不确定，我知道我没有把它放在那里，但是将它注释掉并修复JDBC Url中剩余的配置错误解决了这个问题！

Answer 2

确保提供数据库配置。例如，如果您使用的是Play Framework教程，请取消注释此部分。

# Database configuration
# ~~~~~ 
# You can declare as many datasources as you want.
# By convention, the default datasource is named `default`
#
# db.default.driver=org.h2.Driver
# db.default.url="jdbc:h2:mem:play"
# db.default.user=sa
# db.default.password=""**

有关详细信息，请参阅Play Framework Database Configuration

DB插件未在Play 2.0中注册
