1.. 개요

Undertow를 시작해보자.

2. Maven 프로젝트 생성

이 과정의 설명은 생략한다.

3. pom.xml

    
    <dependency>
      <groupId>io.undertow</groupId>
      <artifactId>undertow-core</artifactId>
      <version>2.0.1.Final</version>
    </dependency>
    <dependency>
      <groupId>io.undertow</groupId>

 4. 코드

package io.sarc.undertowTest;

import io.undertow.Undertow;
import io.undertow.server.HttpHandler;
import io.undertow.server.HttpServerExchange;
import io.undertow.util.Headers;

public class HelloWorldServer {
    public static void main(String[] args) {
         Undertow server = Undertow.builder()
                    .addHttpListener(8080, "localhost")
                    .setHandler(new HttpHandler() {
                        public void handleRequest(final HttpServerExchange exchange) throws Exception {
                            exchange.getResponseHeaders().put(Headers.CONTENT_TYPE, "text/plain");
                            exchange.getResponseSender().send("Hello sarc.io");
                        }
                    }).build();
            server.start();
    }
}
