如何在javalin中给出日志路径

Question

public class App {
    //private static final Logger logger = LoggerFactory.getLogger(App.class);
    private static Logger logger = LoggerFactory.getLogger(App.class.getName());
    private static ObjectMapper mapper = new ObjectMapper();

    public static void main(String[] args) {
        Integer port = args.length>0?Integer.parseInt(args[0]): 7000;       
        Javalin app = Javalin.create().port(port).start();      

        app.get("/", ctx -> ctx.result("service working"));     
        app.post("/mhbwebservice", handler);        
    }
}

请问关于如何在javalin框架中提供日志路径的建议
