java - 注入(inject) WebJarAssets Controller 期间出现 NoSuchMethodError

Question

我遇到了一个问题，由于 WebJarAssets 资源初始化失败，在运行应用程序时出现 NoSuchMethodError。我希望在我的 scala.html 文件中使用 WebJarAssets，如下所示

<script type='text/javascript' src='@routes.WebJarAssets.at(WebJarAssets.fullPath("react", "react.js"))'></script>
<script type='text/javascript' src='@routes.WebJarAssets.at(WebJarAssets.fullPath("react", "react-dom.js"))'></script>
<script type='text/javascript' src='@routes.WebJarAssets.at(WebJarAssets.fullPath("jquery", "jquery.js"))'></script>

我的build.sbt如下

name := "myApp"
version := "1.0"

lazy val root = (project in file(".")).enablePlugins(PlayJava, SbtWeb, PlayEbean)

scalaVersion := "2.11.8"

JsEngineKeys.engineType := JsEngineKeys.EngineType.Node

libraryDependencies ++= Seq(
    javaJdbc,
    cache,
    javaWs,
    "mysql" % "mysql-connector-java" % "5.1.27",
    "commons-io" % "commons-io" % "2.5" withSources(),
    "org.webjars" % "webjars-play_2.11" % "2.4.0-2",
    //"org.webjars" %% "webjars-play" % "2.5.0",
    "org.webjars" % "react" % "15.3.1",
    "org.webjars.npm" % "react-dom" % "15.0.1",
    "org.apache.poi" % "poi" % "3.14",
    "org.apache.poi" % "poi-ooxml" % "3.14",
    "org.webjars" % "jquery" % "3.1.0",
    "org.apache.pdfbox" % "pdfbox" % "2.0.3",
    "org.webjars" % "highcharts" % "4.2.5",
    "org.webjars" % "material-design-icons" % "3.0.0",
    evolutions,
    "javax.mail" % "mail" % "1.4.7",
    "be.objectify" %% "deadbolt-java" % "2.5.3"
)

resolvers += Resolver.url("Typesafe Ivy releases", url("https://repo.typesafe.com/typesafe/ivy-releases"))(Resolver.ivyStylePatterns)

fork in run := false

如您所见，我尝试了几个不同的 webjar 库我的应用程序的plugin.sbt如下

// The Play plugin
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.5.12")

// Web plugins
addSbtPlugin("com.typesafe.sbt" % "sbt-coffeescript" % "1.0.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-less" % "1.1.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-jshint" % "1.0.4")
addSbtPlugin("com.typesafe.sbt" % "sbt-rjs" % "1.0.8")
addSbtPlugin("com.typesafe.sbt" % "sbt-digest" % "1.1.1")
addSbtPlugin("com.typesafe.sbt" % "sbt-mocha" % "1.1.0")
addSbtPlugin("org.irundaia.sbt" % "sbt-sassify" % "1.4.6")
addSbtPlugin("io.teamscala.sbt" % "sbt-babel" % "1.0.5")

addSbtPlugin("com.typesafe.sbt" % "sbt-gzip" % "1.0.0")
//addSbtPlugin("com.github.stonexx.sbt" % "sbt-babeljs" % "1.0.5")

// Play enhancer - this automatically generates getters/setters for public fields
// and rewrites accessors of these fields to use the getters/setters. Remove this
// plugin if you prefer not to have this feature, or disable on a per project
// basis using disablePlugins(PlayEnhancer) in your build.sbt
addSbtPlugin("com.typesafe.sbt" % "sbt-play-enhancer" % "1.1.0")

// Play Ebean support, to enable, uncomment this line, and enable in your build.sbt using
// enablePlugins(PlayEbean).
 addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "4.0.0-M2")

//sbt plugin for eclipse
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "5.1.0")

运行应用程序后，我得到以下堆栈跟踪

任何有关可能导致此问题的原因的见解都会非常有帮助。

Answer 1

您使用的是 Play 2.5，因此请使用以下依赖项:

"org.webjars" %% "webjars-play" % "2.5.0-4"

并确保您已定义路线:

GET         /assets/*file           controllers.Assets.at(path="/public", file)
