This util allows for mapping any HttpServletRequest and HttpServletResponse to and from API gateway classes
- 
Add Jitpack to repos in gradle.build.kts
repositories { maven { url = uri("https://jitpack.io") } } - 
Add dependency
dependencies { compile("com.github.richarddd:aws-lambda-api-gateway-servlet:master-SNAPSHOT") } 
Example with javalin and aws lambda handler:
class HelloHandler : RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
    companion object{
        val app = Javalin.createStandalone()
        app.get("/") { ctx -> ctx.result("Hello World") }
    }
    override fun handleRequest(input: APIGatewayProxyRequestEvent, context: Context) = app.servlet().serve(input)
}
