玩一玩ktor - 爱码网

看到gradle 5.0 发布，折腾一下。
安装ktor插件，然后创建ktor工程。
玩一玩ktor

然后跑起来

看到这里，也没什么特别的。启动比Spring Boot要快。
创建的工程里给的代码很简单。

fun main(args: Array<String>): Unit = io.ktor.server.netty.EngineMain.main(args)

@Suppress("unused") // Referenced in application.conf
@kotlin.jvm.JvmOverloads
fun Application.module(testing: Boolean = false) {
    install(CallLogging) {
        level = Level.INFO
        filter { call -> call.request.path().startsWith("/") }
    }

    routing {
        get("/") {
            call.respondText("HELLO WORLD!", contentType = ContentType.Text.Plain)
        }
    }
}

我想要是路由稍微多点，怎么写，难道都写一个routing里？
http参数怎么拿？
cookie和session等怎么用？
事务怎么做
和MyBatis怎么结合？难道DAO层也用JetBrains那个？

算了，不想了，又没看完文档，想也白想。其实我比较关注，这个东西是不是性能上会有很大提升，毕竟直接上了netty。
