下面是我的main class代码：

public static void main(String[] args) {
        Vertx vertx = Vertx.vertx();
        vertx.deployVerticle(new MainVerticle(), whenDeployed -> {
                vertx.close();
//              System.exit(0);
            });
    }

字符串
下面是主垂直部分的代码：

public class MainVerticle extends AbstractVerticle {

    private static final ObjectMapper mapper = new ObjectMapper();
    private static final Logger log = LoggerFactory.getLogger(MainVerticle.class);
    
    @Override
    public void start(Promise<Void> startPromise) throws Exception {
        
        Configuration config = null;
        
        try(FileInputStream fin = new FileInputStream("/opt/vertex-proxy/config.json")){
            config = mapper.readValue(fin, Configuration.class);
            
        } catch(Exception e) {
            log.error("Invalid configuration\n{}", e.getCause());
        }
        
        log.info("Started application\n");
        
        ProxyOptions proxyOptions = new ProxyOptions()
                .setHost(config.getProxy().getIp())
                .setPort(config.getProxy().getPort());
                
        WebClientOptions options = new WebClientOptions().setUserAgent("Yash client")
                .setProtocolVersion(HttpVersion.HTTP_2).setHttp2ClearTextUpgrade(false)
                .setConnectTimeout(config.getTarget().getConnectionTimeout())
                .setProxyOptions(proxyOptions);
        
        WebClient client = WebClient.create(vertx, options);

        
        HttpRequest<Buffer> req = client.get(config.getTarget().getPort(), config.getTarget().getIp(), config.getTarget().getUri());
        
        req.send().onSuccess(response -> {
            log.info("Received response with status code: " + response.statusCode());
            log.info("Response:\n" + response.bodyAsString());
            startPromise.complete();
            
        }).onFailure(err -> {
            log.error("Something went wrong\n" + err.getCause());
            startPromise.complete();
        });
        
    }
    
    @Override
    public void stop() throws Exception {
        System.out.println("\nStopping application");
    }

}

当我在Eclipse中运行上面的代码时，它的性能非常好，程序在执行后关闭。但是当我构建一个maven jar并尝试使用命令java -jar application.jar运行jar时，程序执行并显示响应，但它不会退出，除非手动中断。
有谁能提出一个正确的方法来解决这个问题，使它在Eclipse和jar中的行为相同？
我甚至尝试在onSuccess和onFailure块中使用java.lang.System.exit（），也在main类中的whenDeployed块中使用，也在stop（）方法中使用，但仍然观察到类似的行为。
