当我尝试将 Play 2.3 应用程序配置为使用 hikaricp 时，我不断收到以下堆栈跟踪

java.lang.RuntimeException: java.lang.ClassNotFoundException: "com.mysql.jdbc.jdbc2.optional.MysqlDataSource"
 com.zaxxer.hikari.util.PoolUtilities.createInstance(PoolUtilities.java:105)

 scala.collection.SetLike$class.map(SetLike.scala:92)
 scala.collection.AbstractSet.map(Set.scala:47)

我的 build.sbt 包含 mysql-connector，它应该在类路径中

name := """myapp"""

version := "2.3-SNAPSHOT"

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

scalaVersion := "2.11.1"

resolvers += Resolver.url("Edulify Repository", url("http://edulify.github.io/modules/releases/"))(Resolver.ivyStylePatterns)

libraryDependencies ++= Seq(
    javaCore,
    "mysql" % "mysql-connector-java" % "5.1.18",
    javaJdbc,
    "org.codehaus.jackson" % "jackson-mapper-asl" % "1.9.13",
    "com.lowagie" % "itext" % "2.1.7",
    "net.sf.jasperreports" % "jasperreports" % "5.2.0",
    "org.mindrot" % "jbcrypt" % "0.3m",
    javaEbean,
    cache,
    javaWs,
    "com.edulify" %% "play-hikaricp" % "1.4.1"
)

这也是我的 conf/play.plugins 文件：

200:com.edulify.play.hikaricp.HikariCPPlugin

任何帮助，将不胜感激

同样的问题发生在我身上我认为在 hikaricp.prod.properties 文件中你提供
jdbcUrl = " JDBC_CONNECTION "删除引号解决了问题 jdbcUrl = JDBC_CO
