无效的记录器接口

Question

我正在尝试使用 undertow.io API启动一个简单的api服务器。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();

我会得到这个错误：

我认为这是暗流记录器的问题，但我不知道如何解决它。 请帮我:)

Answer 1

您的堆栈跟踪包含很多以下内容：~[？：？]。如果您在 jar 上运行 proguard 以缩小和混淆，则可能会删除您需要的记录器接口。禁用保护，然后重试。

Answer 2

您是否使用了正确的依赖项？我使用了与官方网站中提到的相同的依赖项，它在 Java 1.8 下对我有用。

你好世界服务器.java

package undertow;
import io.undertow.Undertow;
import io.undertow.server.HttpHandler;
import io.undertow.server.HttpServerExchange;
import io.undertow.util.Headers;
public class HelloWorldServer {
public static void main(final String[] args) {      
HelloWorldServer helloWorldServer = new HelloWorldServer();
helloWorldServer.initiateServer();
}
private void initiateServer() {
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 312");
}
}).build();
this.server.start();
}
Undertow server = null;
int port= 8080;
String host = "localhost";
}

Caused by: java.lang.IllegalArgumentException: Invalid logger interface io.undertow.UndertowLogger (implementation not found in org.bukkit.plugin.java.PluginClassLoader@12cb152a)

io.undertow.UndertowLogger是一个界面，它使用jboss.logging注释之一进行注释。编译接口时，会执行注释处理器，这将生成记录器实现。

错误消息意味着，在运行时，JBoss 记录器无法加载实现类。

如果有问题的类是由您构建的，请检查在构建期间是否正在运行注释处理器。Maven有时会发疯并拒绝运行注释处理器。如果是这样，mvn clean通常会解决这个问题。

如果该类由第三方提供，则可能缺少一些依赖项。
