[pdf] Swagger API 문서에서 PDF 생성

REST 프로젝트를 수정하여 프로젝트 빌드시 필요한 정적 문서 (html, pdf 등)를 생성 할 수 있습니다.

Java Maven 프로젝트가있는 경우 아래 pom 스 니펫을 사용할 수 있습니다. 일련의 플러그인을 사용하여 pdf 및 html 문서 (프로젝트의 REST 리소스)를 생성합니다.

1. rest-api-> swagger.json : swagger-maven-plugin
2. swagger.json-> Asciidoc : swagger2markup-maven-plugin
3. Asciidoc-> PDF : asciidoctor-maven-plugin

한 플러그인의 출력이 다음 플러그인의 입력이되므로 실행 순서가 중요합니다.

asciidoctor 플러그인은 작업 할 .adoc 파일이 있다고 가정합니다. swagger2markup 플러그인으로 만든 항목을 단순히 수집하는 항목을 만들 수 있습니다.

include::{generated}/overview.adoc[]
include::{generated}/paths.adoc[]
include::{generated}/definitions.adoc[]

생성 된 html 문서가 war 파일의 일부가되도록하려면 해당 문서가 최상위 레벨에 있는지 확인해야합니다. WEB-INF 폴더의 정적 파일은 제공되지 않습니다. maven-war-plugin에서이 작업을 수행 할 수 있습니다.

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <configuration>
        <warSourceDirectory>WebContent</warSourceDirectory>
        <failOnMissingWebXml>false</failOnMissingWebXml>
        <webResources>
            <resource>
                <directory>${generated.html.directory}</directory>
            <!-- Add swagger.pdf to WAR file, so as to make it available as static content. -->
            </resource>
            <resource>
                <directory>${generated.pdf.directory}</directory>
            <!-- Add swagger.html to WAR file, so as to make it available as static content. -->
            </resource>
        </webResources>
    </configuration>
</plugin>

war 플러그인은 생성 된 문서에서 작동합니다. 따라서 해당 플러그인이 이전 단계에서 실행되었는지 확인해야합니다.
