Quarkus使用Camel调用外部端点,错误：使用quarkus.camel.servlet.url-patterns将至少一个servletMap到路径

我正在尝试实现Camel来提供微服务应用程序，我希望使用自己的标头（带有令牌、别名等）调用HTTP路由。首先，我希望调用外部端点（如“http://outside.endpoint.com“），并接收JSON响应以在内部处理对象。
我的错误：

我的路由中有camel-rest调用来执行 getCompanies bean：

package com.example.control;

import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.model.rest.RestBindingMode;

import javax.enterprise.context.ApplicationScoped;
import javax.ws.rs.core.Response;

@ApplicationScoped
public class CompanyRouter extends RouteBuilder {

    @Override
    public void configure() {
        restConfiguration().component("restlet")
                .host("localhost").port("8056")
                .bindingMode(RestBindingMode.auto);;

        rest("/api/people")
        // HTTP: GET /api
                .get()
                .outType(Response.class)
                .to("bean:getCompaniesBean"); // This will invoke the bean
    }
}

调用方法 listCompanies 的bean：

package com.example.control;

import javax.enterprise.context.ApplicationScoped;
import javax.ws.rs.core.Response;

@ApplicationScoped
public class GetCompaniesBean {

    public Response listCompanies() {

        return Response.ok("Joinha!").build();
    }
}

如果要使用默认值CamelHttpTransportServlet，则可以提供最小配置，并仅设置quarkus.camel.servlet.url-patterns。例如：

quarkus.camel.servlet.url-patterns = /services/*

有关详细信息，请参阅以下文档：
https://camel.apache.org/camel-quarkus/latest/reference/extensions/servlet.html#_additional_camel_quarkus_configuration
除非您真的需要使用servlet，否则使用platform-http组件作为HTTP使用者可能更好更简单：
