1.定义两个类：
CustomHttpHandler.java

import io.undertow.server.HttpHandler;
import io.undertow.server.HttpServerExchange;
import io.undertow.util.StatusCodes;public class CustomHttpHandler implements HttpHandler {private final HttpHandler next;public CustomHttpHandler(HttpHandler next) {this.next = next;}@Overridepublic void handleRequest(HttpServerExchange exchange) throws Exception {if ("TRACE".equals(exchange.getRequestMethod().toString())) {exchange.setStatusCode(StatusCodes.FORBIDDEN);exchange.endExchange();return;}// 其他处理逻辑next.handleRequest(exchange);}
}

UndertowConfigCustomizer.java

import org.springframework.boot.web.embedded.undertow.UndertowServletWebServerFactory;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.stereotype.Component;@Component
public class UndertowConfigCustomizer implements WebServerFactoryCustomizer<UndertowServletWebServerFactory> {@Overridepublic void customize(UndertowServletWebServerFactory factory) {factory.addDeploymentInfoCustomizers(deploymentInfo ->deploymentInfo.addInitialHandlerChainWrapper(httpHandler -> new CustomHttpHandler(httpHandler)));}
}

但是对于spring cloud gateway 网关服务 还需要单独定义过滤器，才能修复
DisableTraceFilter.java

import io.netty.handler.codec.http.HttpMethod;
import org.springframework.core.Ordered;
import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Component;
import org.springframework.web.server.ServerWebExchange;
import org.springframework.web.server.WebFilter;
import org.springframework.web.server.WebFilterChain;
import reactor.core.publisher.Mono;@Component
public class DisableTraceFilter implements WebFilter, Ordered {@Overridepublic int getOrder() {// 确保此过滤器优先于其他过滤器return Integer.MIN_VALUE;}@Overridepublic Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {if (HttpMethod.TRACE.name().equals(exchange.getRequest().getMethod().name())) {// 返回403禁止访问exchange.getResponse().setStatusCode(HttpStatus.FORBIDDEN);return exchange.getResponse().setComplete();}return chain.filter(exchange);}
}
