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。
