  // define your API... via script or MVC:

      * Get a pet by ID.

Now the jooby:spec maven plugin:

<plugin>
  <groupId>org.jooby</groupId>
  <artifactId>jooby-maven-plugin</artifactId>
  <executions>
    <execution>
      <goals>
        <goal>spec</goal>
      </goals>
    </execution>
  </executions>
</plugin>

Start your app and try:

• The Swagger-UI at /swagger
• The swagger.json at /swagger/swagger.json
• The swagger.yml at /swagger/swagger.yml

There are a few options available, let's see what they are:

The path option controls where to mount the Swagger routes:

{
  ...

  new Swagger("docs").install(this);

}

Produces: /docs for swagger-ui, /docs/swagger.json and /docs/swagger.yml. Default path is: /swagger.

The filter option controls what is exported to Swagger:

{
  ...

  new Swagger()
    .filter(route -> {
      return route.pattern().startsWith("/api");
    })
    .install(this);
}

Default filter keeps /api/* routes.

One ore more routes are grouped by a tag. The default tag provider produces pets for a route at /api/pets or /pets. You can specify your own tag provider via:

{
  new Swagger()
    .tag(route -> route.name())
    .install(this);
}

This option turn off the swagger-ui:

{
  ...

  new Swagger()
    .noUI()
    .install(this);
}
