mongodb - 玩!添加reactivemongo插件后框架 Controller 返回EMPTY RESPONSE

Question

我对reactivemongo和Play框架很陌生。当我需要添加 MongoDB 连接时，我正在开发 Play 应用程序。我决定使用reactiveMongo，并根据此处的教程制作了所有内容: https://github.com/sgodbillon/reactivemongo-demo-app

我遇到的问题是，在添加插件并配置它之后，我开始从应用程序接收空响应(ERR_EMPTY_RESPONSE)。一旦我删除插件并初始化，我就开始再次接收带有 HTML 文本的正确 Web 应用程序响应。

这是构建文件:

object ApplicationBuild extends Build {

  val appName         = "webapp"
  val appVersion      = "1.0-SNAPSHOT"

  val appDependencies = Seq(
    // Add your project dependencies here,
    jdbc,
    anorm,
    "org.reactivemongo" %% "play2-reactivemongo" % "0.10-SNAPSHOT"
  )
  val main = play.Project(appName, appVersion, appDependencies).settings(
    resolvers += "Sonatype Snapshots" at       "http://oss.sonatype.org/content/repositories/snapshots/"
  )
}

插件配置文件是典型的，只有一行:

400:play.modules.reactivemongo.ReactiveMongoPlugin

这是我在启动和页面打开期间的控制台输出:

--- (Running the application from SBT, auto-reloading is enabled) ---

[info] play - Listening for HTTP on /0:0:0:0:0:0:0:0:9000

(Server started, use Ctrl+D to stop and go back to the console...)

[info] application - ReactiveMongoPlugin starting...
[info] application - ReactiveMongoPlugin successfully started with db 'users'! Servers:
                [localhost:27017]
[info] play - Application started (Dev)
[WARN] [08/16/2013 23:12:28.922] [New I/O worker #1] [EventStream(akka://play)]     [akka.event-handlers] config is deprecat
ed, use [akka.loggers]

造成这种行为的原因是什么？

经过多次迭代，我发现这是一个版本不匹配问题，二进制不兼容。始终确保检查用于编译每个库的版本，因为有时它不会显示有关二进制不兼容的错误。
