我在春季启动应用中使用camelServlet和camel kafka，但遇到了我无法理解的错误
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");
我已经定义了骆驼servlet bean如下：
@Bean
public ServletRegistrationBean camelServletRegistrationBean() {
ServletRegistrationBean registration = new ServletRegistrationBean(new CamelHttpTransportServlet(), "/camel/*");
registration.setName("CamelServlet");
return registration;

发出获取请求时，我是否需要在标头中添加camelContext？
