apache camel-我正在尝试使用pollench。
这将继续询问db是否有特定id的记录可用，如果是，则返回结果，否则保持轮询至少90秒。通过envoking crud repository服务（按id查找）可以找到。
但是，下面的实现出现了一个获取错误-请有人就如何使用pollench提出建议

SasdBean dBean = new SasdBean();

        SimpleRegistry registry = new SimpleRegistry();
        Map<Class<?>, Object> params = new HashMap<Class<?>, Object>();
        params.put(SasdBean.class, dBean);
        // bind the params
        registry.put("params", params);

        CamelContext context = new DefaultCamelContext(registry);

        Processor myProcessor = new Processor() {
            public void process(Exchange exchange) {
                //   String correlationId = exchange.getIn().getBody(String.class);
                LOGGER.info("Called with exchange  : " + exchange.getIn().getBody().toString());
                // ResponseDTO response= responseService.retrieveResponseByCorrelationId(correlationId);
                //exchange.getOut().setBody(response);
                //  LOGGER.info("Called with exchange: " + exchange);
            }
        };

        context.addRoutes(new RouteBuilder() {
            @Override
            public void configure() throws Exception {
                from("direct:start")
                        .pollEnrich().method(SasdBean.class,"doSomething")
                        .timeout(9000)
                        .to("seda:end");

            }
        });

        context.start();

        ProducerTemplate producerTemplate = context.createProducerTemplate();
        producerTemplate.sendBody("direct:start",correlationId);

        ConsumerTemplate consumerTemplate = context.createConsumerTemplate();
        String sasdResponse = consumerTemplate.receiveBody("seda:end",String.class);
        LOGGER.info("Results : "+ sasdResponse);

我得到的错误。
