You can modify your REST project, so as to produce the needed static documents (html, pdf etc) upon building the project.
If you have a Java Maven project you can use the pom snippet below. It uses a series of plugins to generate a pdf and an html documentation (of the project's REST resources).
- rest-api -> swagger.json : swagger-maven-plugin
- swagger.json -> Asciidoc : swagger2markup-maven-plugin
- Asciidoc -> PDF : asciidoctor-maven-plugin
Please be aware that the order of execution matters, since the output of one plugin, becomes the input to the next:

The asciidoctor plugin assumes the existence of an .adoc file to work on.
You can create one that simply collects the ones that were created by the swagger2markup plugin:
include::{generated}/overview.adoc[]
include::{generated}/paths.adoc[]
include::{generated}/definitions.adoc[]
If you want your generated html document to become part of your war file you have to make sure that it is present on the top level - static files in the WEB-INF folder will not be served.
You can do this in the maven-war-plugin:
<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>
The war plugin works on the generated documentation - as such, you must make sure that those plugins have been executed in an earlier phase.
