That was when it all began.

UndertowからVert.xバックエンドになった、QuarkusのRESTEasyを試す

Quarkus RESTEasy

これは、なにをしたくて書いたもの？

最近Quarkusを触っていなかったのですが、少し前にRESTEasyのバックエンドがUndertowからVert.xに移ったという話を見たので、
1度見ておこうかなと。

Quarkus 0.24.0 released - Vert.x everywhere

Quarkus 0.23.2 released - Back on track

Quarkus 0.23.1 released - Paving the way to our new HTTP layer

0.24.0で完全に移行していて、0.23.1から移り始めていたんですね。2019年9月の話ですねぇ。

久しぶりに、ちょっと試してみましょう。

環境

今回の環境は、こちら。

$ java -version
openjdk version "1.8.0_232"
OpenJDK Runtime Environment (build 1.8.0_232-8u232-b09-0ubuntu1~18.04.1-b09)
OpenJDK 64-Bit Server VM (build 25.232-b09, mixed mode)


$ $GRAALVM_HOME/bin/native-image --version
GraalVM Version 19.2.1 CE


$ mvn --version
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: $HOME/.sdkman/candidates/maven/current
Java version: 1.8.0_232, vendor: Private Build, runtime: /usr/lib/jvm/java-8-openjdk-amd64/jre
Default locale: ja_JP, platform encoding: UTF-8
OS name: "linux", version: "4.15.0-74-generic", arch: "amd64", family: "unix"

サンプルプロジェクト

今回は、RESTEasy＋JSON（Jackson）な構成でいきましょう。

プロジェクトの作成。今回使用するQuarkusのバージョンは、1.1.1.Finalです。

$ mvn io.quarkus:quarkus-maven-plugin:1.1.1.Final:create \
    -DprojectGroupId=org.littlewings \
    -DprojectArtifactId=resteasy-vertx-jackson \
    -Dextensions="resteasy-jackson"

作成されたディレクトリに移動。

$ cd resteasy-vertx-jackson

pom.xmlに書かれた依存関係は、こんな感じです。

  <dependencies>
    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-resteasy</artifactId>
    </dependency>
    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-junit5</artifactId>
      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>io.rest-assured</groupId>
      <artifactId>rest-assured</artifactId>
      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-resteasy-jackson</artifactId>
    </dependency>
  </dependencies>

Mavenで依存関係を見てみましょう。

$ mvn dependency:tree

こんな感じの結果に。

というか、Servletすらいないじゃないですか。JAX-RSのSpecは、さすがにいますね。

今回は、書籍をお題にコードを書いてみます。

書籍クラス。
src/main/java/org/littlewings/quarkus/resteasy/Book.java

package org.littlewings.quarkus.resteasy;

public class Book {
    private String isbn;
    private String title;
    private int price;

    // getter／setterは省略
}

JAX-RSリソースクラス。
src/main/java/org/littlewings/quarkus/resteasy/BookResource.java

package org.littlewings.quarkus.resteasy;

import java.util.ArrayList;
import java.util.List;
import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;

import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.UriInfo;

@Path("book")
public class BookResource {
    Map<String, Book> books = new ConcurrentHashMap<>();

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public List<Book> books() {
        return new ArrayList<>(books.values());
    }

    @GET
    @Path("{isbn}")
    @Produces(MediaType.APPLICATION_JSON)
    public Book find(@PathParam("isbn") String isbn) {
        return books.get(isbn);
    }

    @PUT
    @Path("{isbn}")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    public Response create(Book book, @Context UriInfo uriInfo) {
        books.put(book.getIsbn(), book);

        return Response.created(uriInfo.getRequestUriBuilder().build()).build();
    }
}

パッケージングして、

$ mvn package

起動。

$ java -jar target/resteasy-vertx-jackson-1.0-SNAPSHOT-runner.jar

認識しているExtensionに、Servletはいません。

Servlet APIの代わりや、スレッドの情報を見る

ところで、ここまでだと特に面白味がないので、HttpServletRequest代わりの情報とかどうしたらいいんだろう？というところだと、
RESTEasyのSPIを使うみたいです。

HttpRequest (RESTEasy JAX-RS 4.4.1.Final API)

Servlet compatibility

https://docs.jboss.org/resteasy/docs/4.4.1.Final/javadocs/org/jboss/resteasy/spi/package-summary.html

あと、スレッドの情報とか気になったりします。

というわけで、こんなJAX-RSリソースクラスを使って確認。
src/main/java/org/littlewings/quarkus/resteasy/HttpRequestResource.java

package org.littlewings.quarkus.resteasy;

import java.util.LinkedHashMap;
import java.util.Map;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;

import org.jboss.logging.Logger;
import org.jboss.resteasy.spi.HttpRequest;

@Path("http-request")
public class HttpRequestResource {
    Logger logger = Logger.getLogger(HttpRequestResource.class);

    @GET
    @Path("print-request")
    @Produces(MediaType.APPLICATION_JSON)
    public Map<String, Object> printRequest(@Context HttpRequest request) {
        Map<String, Object> response = new LinkedHashMap<>();

        response.put("method", request.getHttpMethod());
        response.put("request-uri", request.getUri().getRequestUri().toString());
        response.put("path", request.getUri().getPath());
        response.put("query", request.getUri().getRequestUri().getQuery());

        return response;
    }

    @GET
    @Path("thread-dump")
    @Produces(MediaType.TEXT_PLAIN)
    public String printThreadDump() {
        logger.infof("Thread[%s / %s]", Thread.currentThread().getName(), Thread.currentThread().getClass().getName());

        Thread.dumpStack();

        return "print Thread Dump";
    }
}

確認。

$ curl -s localhost:8080/http-request/print-request?param=hoge | jq
{
  "method": "GET",
  "request-uri": "http://localhost:8080/http-request/print-request?param=hoge",
  "path": "/http-request/print-request",
  "query": "param=hoge"
}


$ curl -s http://localhost:8080/http-request/thread-dump
print Thread Dump

スレッドダンプは、こんな感じでした。

スレッドプールの情報を追うと、このあたりのようです。

quarkus/ExecutorRecorder.java at 1.1.1.Final · quarkusio/quarkus · GitHub

https://quarkus.io/guides/all-config#quarkus-core_quarkus.thread-pool.core-threads

https://github.com/quarkusio/quarkus/blob/1.1.1.Final/core/runtime/src/main/java/io/quarkus/runtime/ThreadPoolConfig.java

他のバージョンだと、Vert.xのスレッドプールで調整しているようだったので、バージョンごとにだいぶ変わるんですねぇ…。

Servlet APIを使う

RESTEasyのバックエンドを、Vert.xではなくUndertowにするには、Undertow Extensionを追加します。

$ mvn quarkus:add-extension -Dextensions=quarkus-undertow

依存関係に、こちらが追加されます。

    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-undertow</artifactId>
    </dependency>

「mvn dependency:tree」で依存関係を見ると、Servlet APIは追加されるものの、その背後にいるのはVert.xですね。

アプリケーションの起動時には、ExtensionとしてServletが認識されています。

起動時に、XNIOのログも出力されず、スレッドダンプを取ったりするとNettyが現れるので、完全にNettyベースになったんですねぇ。

ここでは、がっつりとUndertowのAPIが登場します。

この状態だと、Servlet APIが利用可能になります。

    @GET
    @Path("print-servlet-request")
    @Produces(MediaType.APPLICATION_JSON)
    public Map<String, Object> printServletRequest(@Context HttpServletRequest request) {
        Map<String, Object> response = new LinkedHashMap<>();

        response.put("method", request.getMethod());
        response.put("request-url", request.getRequestURL());
        response.put("request-uri", request.getRequestURI());
        response.put("query", request.getQueryString());

        return response;
    }

確認。

$ curl -s localhost:8080/http-request/print-servlet-request?param=hoge | jq
{
  "method": "GET",
  "request-url": "http://localhost:8080/http-request/print-servlet-request",
  "request-uri": "/http-request/print-servlet-request",
  "query": "param=hoge"
}

メソッド追加後のコードは、こちら。
src/main/java/org/littlewings/quarkus/resteasy/HttpRequestResource.java

package org.littlewings.quarkus.resteasy;

import java.util.LinkedHashMap;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;

import org.jboss.logging.Logger;
import org.jboss.resteasy.spi.HttpRequest;

@Path("http-request")
public class HttpRequestResource {
    Logger logger = Logger.getLogger(HttpRequestResource.class);

    @GET
    @Path("print-request")
    @Produces(MediaType.APPLICATION_JSON)
    public Map<String, Object> printRequest(@Context HttpRequest request) {
        Map<String, Object> response = new LinkedHashMap<>();

        response.put("method", request.getHttpMethod());
        response.put("request-uri", request.getUri().getRequestUri().toString());
        response.put("path", request.getUri().getPath());
        response.put("query", request.getUri().getRequestUri().getQuery());

        return response;
    }

    @GET
    @Path("thread-dump")
    @Produces(MediaType.TEXT_PLAIN)
    public String printThreadDump() {
        logger.infof("Thread[%s / %s]", Thread.currentThread().getName(), Thread.currentThread().getClass().getName());

        Thread.dumpStack();

        return "print Thread Dump";
    }

    @GET
    @Path("print-servlet-request")
    @Produces(MediaType.APPLICATION_JSON)
    public Map<String, Object> printServletRequest(@Context HttpServletRequest request) {
        Map<String, Object> response = new LinkedHashMap<>();

        response.put("method", request.getMethod());
        response.put("request-url", request.getRequestURL());
        response.put("request-uri", request.getRequestURI());
        response.put("query", request.getQueryString());

        return response;
    }
}

ところでですね、依存関係にUndertowの名前がほとんど登場しなかったのに、スレッドダンプを見たらいきなり出てきたのがちょっと
気になります。

どうやら、こちらが実体のようですね。

GitHub - quarkusio/quarkus-http

A Vert.x based Servlet implementation.

らしいです。

こちらに置かれているコードのパッケージは、「io.undertow」となっていますし。

とりあえず、見たかったものはざっくりと見れたので、ここまで。
