我已经在我的应用程序中将play框架更新到版本2.1，但它不能再工作了。
这是一个简单的控制器：
package controllers
import play.api._
import play.api.mvc._
import models.Country
import ru.circumflex.orm._
object Application extends Controller {
def index = Action {
val co = Country AS "co"
val q = SELECT (co.*) FROM (co)
val countries: Seq[Country] = q.list()
Ok(views.html.index(countries))
}
}
这是一个国家的模型：
package models
import ru.circumflex.orm.{TextField, Table, Record}
import java.util.regex.Pattern
class Country extends Record[String, Country] {
def PRIMARY_KEY = code
def relation = Country
def this(code: String, name: String) = {
this()
this.code := code
this.name := name
}
val code: TextField[Country] = "code".VARCHAR(2).NOT_NULL
val name = "name".TEXT.NOT_NULL
def cities = inverseMany(City.country)
override def toString = name.getOrElse("unknow")
}
object Country extends Country with Table[String, Country] {
val codeKey = UNIQUE(code)
val codeChk = CONSTRAINT("code_chk").CHECK("code IN ('ch', 'us', 'uk', 'fr', 'es', 'it', 'pt', 'by')")
val idx = "country_code_idx".INDEX("LOWER(code)").USING("btree").UNIQUE
validation.notNull(_.code)
.notEmpty(_.code)
.pattern(_.code, Pattern.compile("(?i:[a-z]{2})"))
}
当页面打开时，出现以下错误：

任何人都可以帮我解决这个问题吗？
答案 0 :(得分：0)
Circumflex 2.x似乎不是针对scala 2.10（播放2.1所需）构建的。
circumflex 3.0正在2.10中构建，但其当前仅在快照中。 您可以在此处获取快照：
https://oss.sonatype.org/content/repositories/snapshots/
请注意，软件包名称已从 ru.circumflex 更改为 pro.savant.circumflex ，因此您可能需要重构导入语句。
答案 1 :(得分：0)
我使用以下信息修复了它：reference
首先从Github获取最后一个版本的circumflex：
git clone git://github.com/inca/circumflex.git
根据建议，更改文件orm / src / main / scala / relation.scala中的行
第55行：
val _recordClass: Class[R] = Class.forName(
以
val _recordClass: Class[R] = this.getClass().getClassLoader().loadClass(
现在我们可以在Play 2.1应用程序中编译，安装和使用
cd circumflex
mvn clean install
如果您只需要一个模块：
cd circumflex
mvn clean install -pl <circumflex-orm> -am
现在编辑您的project/Build.scala文件以添加依赖项和本地代表
val appDependencies = Seq(
"pro.savant.circumflex" % "circumflex-orm" % "3.1-SNAPSHOT"
)
val main = play.Project(appName, appVersion, appDependencies).settings(defaultScalaSettings:_*).settings(
resolvers += "Local Maven Repository" at "file:"+Path.userHome.absolutePath+"/.m2/repository"
)
