Spring Boot 1.2.RC2からついに[Undertowがサポートされた](http://spring.io/blog/2014/11/21/spring-boot-1-2-0-rc2-available-now)ので、使ってみた。
これでSpring Bootでは
* Tomcat
* Jetty
* Undertow
のどれかを組み込みサーバーとして使うことが出来る。
起動時間の差を調べてみよう。
[前にもやった](http://blog.ik.am/#/entries/281)が、Spring Bootのバージョンが上がったので、組み込みサーバーのバージョンが上がっている。
Spring MVCを抜いて、素のサーブレットが一個あるだけの状態でそれぞれ起動時間を計測した。10回やって最速だったものを貼っていく。(MBA 11-inch, Mid 2011)
サンプルコードは[こちら](https://blog.ik.am/api/v1/files/696b770d-120b-4070-800e-84ac4effcfff/servlet-sample.zip)。

Undertow > Tomcat > Jettyな順番になっちゃった。Jettyの方が速い印象があるの意外だった。（というか普段Jettyの方が体感1秒くらい速い）きっと比較の仕方も良くないのだろう。
とにかくUndertowが使えてうれしいですね。
ちなみにRC2のUndertow対応だと依存関係が足りなくて、BeanValidationを使うと(`spring-boot-starter-web`に含まれる)起動時にこけます。以下の依存関係追加が必要。
org.jboss.spec.javax.el
jboss-el-api_3.0_spec
1.0.4.Final
面倒くさいから次のバージョンで入れてもらえるように[Pull Request送りました](https://github.com/spring-projects/spring-boot/pull/1979)。
