在Accept标头中没有“application/json”属性的Apache Camel REST API上的HTTP请求导致错误

我正在使用Apache Camel REST API运行Sping Boot 应用程序。它按我预期的方式工作，除了当我发送接受头中没有“application/json”属性的HTTP GET请求时，应用程序引发错误，并返回代码为200和空正文的HTTP响应。我希望应用程序无论如何都能发送正确的响应。
我无法找到在Sping Boot 中管理此行为的方法。
基本路由类：

import io.patriot_framework.virtual_smart_home.AppConfig;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.model.rest.RestBindingMode;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.stereotype.Component;

/**
 * Routing configuration for localhost:8080.
 */
@Component
public class BaseRoute extends RouteBuilder {

    private AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(AppConfig.class);

    @Override
    public void configure() throws Exception {
        restConfiguration()
                .component("servlet")
                .host("localhost").port(8080)
                .bindingMode(RestBindingMode.auto);
    }
}

房屋路线：

import io.patriot_framework.virtual_smart_home.house.House;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
import org.springframework.stereotype.Component;

/**
 * House endpoint which allows HTTP GET request only and returns information
 * about the whole {@code House} object.
 */
@Component
public class HouseRoute extends BaseRoute {

    @Autowired House house;

    @Override
    public void configure() throws Exception {
        rest(getRoute())
                .get()
                    .produces(MediaType.APPLICATION_JSON_VALUE)
                    .route()
                    .process(exchange -> exchange.getMessage().setBody(house))
                    .endRest();
    }

    protected String getRoute() {
        return "house/";
    }
}

错误：

出于某种原因，当我将bindingMode从RestBindingMode.auto更改为RestBindingMode.json时，它起了作用。
