java - Undertow 无效记录器接口(interface)

Question

我正在尝试使用 undertow.io 启动一个简单的 api 服务器API。这是我的启动代码。

this.server = Undertow.builder().addHttpListener(this.port, this.host).setHandler(new HttpHandler() {
        @Override
        public void handleRequest(HttpServerExchange exchange) throws Exception {
            exchange.getResponseSender().send("Hello World");
        }
    }).build();
   this.server.start();

我会收到此错误:

我认为这是 undertow 记录器的问题，但我不知道如何修复它。请帮助我:)

你的堆栈跟踪包含很多这些东西:~[?:?]。如果您在 jar 上运行 proguard 来缩小和混淆，那么它可能会删除您需要的记录器接口(interface)。禁用混淆器并重试。
