Add morphia into Play 2.0

明年今日 — Wed, 11 Apr 2012 14:23:00 GMT

There are two ways of adding morphia jar file into play 2.0.
Demo source code can be found at: https://github.com/czihong/playMongoDemo

1. Unmanaged dependencies
1.1 download morphia jar file from http://code.google.com/p/morphia/downloads/list
1.2 save morphia-0.99.jar into your {playProjectDIr}/lib
1.3 add this jar file to your project classpath

2. Managed Dependencies
Modified the Build.scala file

import sbt._
import Keys._
import PlayProject._

object ApplicationBuild extends Build {

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

    val appDependencies = Seq(
            // Add your project dependencies here,
        "com.google.code.morphia" % "morphia" % "0.99"
    )

    val main = PlayProject(appName, appVersion, appDependencies, mainLang = JAVA).settings(
            // Add your own project settings here
            resolvers += "Maven repository" at "http://morphia.googlecode.com/svn/mavenrepo/"
    )
}

I saw this error occur as well.  I am using Scala but the same error occured at the same location.  I see you have included the slf4j library in your classpath.

Did you take a look at http://code.google.com/p/morphia/wiki/SLF4JExtension ?
You need to include the extension in your classpath and then ensure you call the following code at start-up to register the logger extension and the error disappears.  You can put it in a static {} block if you prefer.

For the explain, see the build system of play 2.0 document.
