我如何从ApacheCammel路由接收到Spring引导控制器的响应

通过使用consumertemplate将数据从路由发送到endpointdirect:receive，我在控制器中接收相同的数据，但错误如下

[骆驼（骆驼-1）线#1- JmsConsumer[MQT.EI.PRD2X4_PRODUCER_UT.REPLY.Q1]]错误 o、 a.c.processor.DefaultErrorHandler.log-为的传递失败 （消息ID:ID:C3E2D840D4D8E3F1404040400D85C2573B4CF7342打开 交换ID:ID-APINP-ELPT60235-1597255599355-0-5）。筋疲力尽 传递尝试：1捕获： org.apache.camel.component.direct.DirectConsumerNotAvailableException： 终结点上没有可用的使用者：direct://recive. 交易所[ID-APINP-ELPT60235-1597255599355-0-5]

是否有人能就如何从控制器的路径获取响应数据给出建议

控制器代码：

@Autowired
    private CamelContext camelContext;
    @Autowired
    private ProducerTemplate producer;
    @Autowired
        ConsumerTemplate consumer;

    @PostMapping("/request-reply")
    public String requestReplyMapping(@RequestBody String inputReq) {

        Exchange exchangeRequest = ExchangeBuilder.anExchange(camelContext).withBody(inputReq).build();
        Exchange exchangeResponse = producer.send("direct:request-reply", exchangeRequest);

        Exchange receive = consumer.receive("direct:receive"); //receiving data from this endpoint
        return null;

    }

@Component
public class RequestReplyRouter extends RouteBuilder {

    @Override
    public void configure() throws Exception {

        from("direct:request-reply").
        to("jms:RequestQueue?ReplyTo=ResponseQueue&exchangePattern=InOut")
        .log("Request-reply Body is  ${body}   and header info is   ${headers}  ");

        from("jms:ResponseQueue")
        .log("Received Body is  ${body}   and header info is   ${headers}  ")
        .to("direct:receive"); // sending data to the endpoint
    }

}

路线代码：

@Autowired
    private CamelContext camelContext;
    @Autowired
    private ProducerTemplate producer;
    @Autowired
        ConsumerTemplate consumer;

    @PostMapping("/request-reply")
    public String requestReplyMapping(@RequestBody String inputReq) {

        Exchange exchangeRequest = ExchangeBuilder.anExchange(camelContext).withBody(inputReq).build();
        Exchange exchangeResponse = producer.send("direct:request-reply", exchangeRequest);

        Exchange receive = consumer.receive("direct:receive"); //receiving data from this endpoint
        return null;

    }

@Component
public class RequestReplyRouter extends RouteBuilder {

    @Override
    public void configure() throws Exception {

        from("direct:request-reply").
        to("jms:RequestQueue?ReplyTo=ResponseQueue&exchangePattern=InOut")
        .log("Request-reply Body is  ${body}   and header info is   ${headers}  ");

        from("jms:ResponseQueue")
        .log("Received Body is  ${body}   and header info is   ${headers}  ")
        .to("direct:receive"); // sending data to the endpoint
    }

}

您不需要一个consumerTemplate来完成您的尝试。默认情况下，Direct组件的交换模式为InOut。因此，您可以使用

exchangereresponse

变量在处理骆驼路线后获取交换

骆驼路线：

from("direct:start")
.log("${body} in stat")
.transform().simple("text")
.to("direct:nextRoute");

from("direct:nextRoute")
.log("${body} in nextRoute");

休息控制器：

public class RestController{

    final static String CAMEL_START_URI ="direct:start";

    @Autowired
    CamelContext camelContext;

    @Autowired
    @EndpointInject(uri=CAMEL_START_URI)
    ProducerTemplate producer;

    @PostMapping(value = "/request")
    public String requestMapping(@RequestBody String inputReq) {
        
        Exchange sendExchange = ExchangeBuilder.anExchange(camelContext).withBody(inputReq).build();
        Exchange outExchange = producer.send(sendExchange);
        String outString = outExchange.getMessage().getBody(String.class);
        System.out.println(outString); //this will have a value of "text" since I am setting the body as "text" in the second route
        return outString; 
    }

}

我很感激你的时间，但我仍然面临其他问题，请你检查一下好吗
