【问题描述】：
我在 Spring Boot 应用程序中使用 camelServlet、camel kafka，我收到了这个我无法理解的错误
当我尝试调用配置为 REST DSL 路由的 get 端点时，出现以下错误
路线：
rest().get("/getBatchID")
.to("direct:getBatchID");
我已将骆驼 servlet bean 定义如下：
@Bean
public ServletRegistrationBean camelServletRegistrationBean() {
ServletRegistrationBean registration = new ServletRegistrationBean(new CamelHttpTransportServlet(), "/camel/*");
registration.setName("CamelServlet");
return registration;

发出get请求时是否需要在header中添加camelContext？？
