Java 部署多模块播放项目

我正在尝试使用SBT部署一个多模块播放项目。 我们的项目有5个模块

[公共空间，频道，…]

。 当我在本地系统中使用

sbt run

时，一切正常。 对于在服务器中部署，我使用

sbt dist

to。 但是，当我使用由

sbt dist

生成的脚本运行应用程序时，问题就出现了

以下是一个错误示例：

[error] error_handler - Unhandled Error
java.lang.IllegalArgumentException: No query defined for that name [automaticChannel.getTagByChannelId]
    at org.hibernate.internal.AbstractSharedSessionContract.buildQueryFromName(AbstractSharedSessionContract.java:770)

通用存储库类存在于公共资源模块中，自动渠道存储库存在于渠道模块中

buid.sbt

文件的一部分：

lazy val connector = (project in file("modules/connector"))
  .enablePlugins(PlayScala)
  .settings(
    commonSettings,
    libraryDependencies += "org.mindrot" % "jbcrypt" % "0.4"
  )

lazy val common = (project in file("modules/common"))
  .enablePlugins(PlayJava)
  .dependsOn(connector)
  .settings(
    commonSettings,
    libraryDependencies ++= Seq(
      javaJdbc,
      filters,
      guice,
      javaWs,
      ehcache,
      javaJpa,

      "org.jsoup" % "jsoup" % "1.10.1",
      "com.thoughtworks.xstream" % "xstream" % "1.3"
    )
  )

lazy val search = (project in file("modules/search")).enablePlugins(PlayJava).dependsOn(common).settings(commonSettings)
lazy val channel = (project in file("modules/channel")).enablePlugins(PlayJava).dependsOn(common, search).settings(commonSettings)
lazy val recommend = (project in file("modules/recommend")).enablePlugins(PlayJava).dependsOn(common, search).settings(commonSettings)

lazy val root = (project in file("."))
  .enablePlugins(PlayJava)
  .dependsOn(channel, recommend)
  .aggregate(channel, recommend)
  .settings(commonSettings)

我想知道

sbt run

和

sbt dist

之间有什么区别

部署多模块SBT项目的常用和推荐方法是什么

这是一个类路径问题。您必须在build.sbt中放入以下代码：

PlayKeys.externalizeResources := false

---

默认情况下，项目中的资源不会打包在由

sbtdist

创建的jar文件中
