我刚刚将我的应用程序移植到Play 2.2并修改了一些代码以使用最新版本SecureSocial- 我已经看到案例类UserId已重命名为IdentityId. 好吧，我可以注册一个新用户......并且数据已成功保存到 MongoDB：

> db.identities.find()
{ "_id" : ObjectId("5256a6ffe4b000f9ba0b6ce5"), "identityId" : { "userId" : "joey", "providerId" : "userpass" }, "firstName" : "Joey", "lastName" : "Smith", "fullName" : "Joey Smith", "email" : "joey@mydomain.com", "authMethod" : { "method" : "userPassword" }, "passwordInfo" : { "hasher" : "bcrypt", "password" : "$2a$10$vDr02XZ5dAHmJHDexbBnROWejhtnYFufPJtHPr8IT.rqsCSAAu5Ju" } }

...但是一旦我尝试登录 - 当然这意味着从 MongoDb 读取数据，玩具不再工作。NoSuchElementException由于数据不是从数据库中读取的，我总是得到一个。

下面是我的完整代码：

  def findByEmailAndProvider(email: String, providerId: String): Option[AccountIdentity] = {
    dao.findOne(DBObject("email" -> email, "_id.providerId" -> providerId))
  }
}

/**

  import IdentityId._

  import PasswordInfo._

  /**

   */
  implicit val identityJsonWrite = new Writes[AccountIdentity] {
    def writes(identity: AccountIdentity): JsValue = {
      Json.obj(
        "identityId" -> identity.identityId,
        "firstName" -> identity.firstName,
        "lastName" -> identity.lastName,
        "fullName" -> identity.fullName,
        "email" -> identity.email,
        "avatarUrl" -> identity.avatarUrl,
        "authMethod" -> identity.authMethod,
        "oAuth1Info" -> identity.oAuth1Info,
        "oAuth2Info" -> identity.oAuth2Info,
        "passwordInfo" -> identity.passwordInfo
      )
    }
  }

  /**
   * An [[AccountIdentity]] deserialized from JSON.
   */
  implicit val identityJsonRead = (
    (__ \ 'identityId).read[IdentityId] ~
    (__ \ 'firstName).read[String] ~
    (__ \ 'lasttName).read[String] ~
    (__ \ 'fullName).read[String] ~
    (__ \ 'email).readNullable[String] ~
    (__ \ 'avatarUrl).readNullable[String] ~
    (__ \ 'authMethod).read[AuthenticationMethod] ~
    (__ \ 'oAuth1Info).readNullable[OAuth1Info] ~
    (__ \ 'oAuth2Info).readNullable[OAuth2Info] ~
    (__ \ 'passwordInfo).readNullable[PasswordInfo]
  )(AccountIdentity)
}

如您所见，我正在使用复合键......所以也许我在方法find和findByEmailAndProvider.

EDIT1： ...当然，我还实现了序列化/反序列化IdentityId：

import play.api.libs.json._
import play.api.libs.functional.syntax._

/**
 * Provides functionality for serializing/deserializing [[securesocial.core.IdentityId]]
 * data to/from JSON.
 */
object IdentityId {

  /**
   * An `IdentityId` serialized to JSON.
   */
  implicit val identityIdJsonWrite = new Writes[securesocial.core.IdentityId] {
    def writes(identityId: securesocial.core.IdentityId): JsValue = {
      Json.obj(
        "userId" -> identityId.userId,
        "providerId" -> identityId.providerId
      )
    }
  }

  /**
   * An `IdentityId` deserialized from JSON.
   */
  implicit val identityIdJsonRead = (
    (__ \ 'userId).read[String] ~
    (__ \ 'providerId).read[String]
  )(securesocial.core.IdentityId.apply _)
}

找到...我只需要重新映射identityId到_id：

import com.novus.salat._
import com.mongodb.casbah.Imports._

import play.api.Play
import play.api.Play.current

/**
 * Defines a custom Salat context for MongoDB.
 */
package object mongodbContext {

  /**
   * The custom context that globally overrides the Salat defaults.
   */
  implicit val context = {
    val context = new Context {
      val name = "global"
      override val typeHintStrategy = StringTypeHintStrategy(when = TypeHintFrequency.WhenNecessary, typeHint = "_t")
    }

    context.registerGlobalKeyOverride(remapThis = "identityId", toThisInstead = "_id")
    context.registerClassLoader(Play.classloader)
    context
  }
}

...最终数据库中的数据是正确的：

> db.identities.find()
{ "_id" : { "userId" : "joey", "providerId" : "userpass" }, "firstName" : "Joey", "lastName" : "Smith", "fullName" : "Joey Smith", "email" : "joey@mydomain.com", "authMethod" : { "method" : "userPassword" }, "passwordInfo" : { "hasher" : "bcrypt", "password" : "$2a$10$lWxiZz3XJcj3ckOOTTgleOo3tBy2zZvO.LfX9jeUtatHENcTHQ.hS" } }
