Scala WebApplication + Maven 프로젝트 구성

Scala WebApplication + Maven 프로젝트 구성

1. WebApplication프로젝트 작성

mvn archetype:create -DgroupId=com.babukuma -DartifactId=Scala.Web -DarchetypeArtifactId=maven-archetype-webapp

2. 디렉토리 구성
 - java소스
  ・src/main/java
  ・src/test/java (테스트용)
 - scala소스
  ・src/main/scala
  ・src/test/scala (테스트용)
 - resources
  ・src/main/resources
  ・src/test/resources (테스트용)
 - WebApplication파일
  ・src/main/webapp
  ・src/test/webapp (테스트용)

package com.babukuma

import javax.servlet.http._

class HelloScalaServlet extends HttpServlet {
 override def doGet(request : HttpServletRequest, response : HttpServletResponse) = 
  response.getWriter().print("Hello Scala")
}
