增加一个带入参 name的页面
http://127.0.0.1:9200/hello?name=dog

Create a new page
Add an action method
Define a route
Customize the greeting


项目导入 idea ， 如果出现 找不到 xxx ,可以 sbt 编译下
sbt compile
sbt clean compile

增加模板 hello.scala.html  不会自动编译
直接命令行 sbt 先编译下 

模板 编译生成
/target/scala-2.13/twirl/main/views/html/hello.template.scala

sbt run -Dhttp.port=9200
默认端口 9000

/app/controllers/HomeController.scala

/app/views/hello.scala.html
/conf/routes

GET    /hello    controllers.HomeController.hello(name:String)




@Singleton
class HomeController @Inject()(cc: ControllerComponents) extends AbstractController(cc) {

  def index() = Action { implicit request: Request[AnyContent] =>
    Ok(views.html.index())
  }
  
  def explore() = Action { implicit request: Request[AnyContent] =>
    Ok(views.html.explore())
  }
  
  def tutorial() = Action { implicit request: Request[AnyContent] =>
    Ok(views.html.tutorial())
  }


  def hello(name: String) = Action {
    Ok(views.html.hello(name))
  }
 
}



@(name: String)
@main("Hello") {
<section id="content">
    <div class="wrapper doc">
        <article>
            <h1>Hello @name!</h1>
        </article>
        <aside>
            @commonSidebar()
        </aside>
    </div>
</section>
}
