您来自rabbit的消息正文类型是byte[]，而您要调用MyDTO类型的bean。您的类型不匹配。Camel找不到可以将消息正文从byte[]转换为MyDTO类型的类型转换器。
来自Rabbit的byte[]数据是XML格式的吗？MyDTO类上是否有JAXB注解，以便可以使用JAXB将其从xml编组到Java？

这是Jaxb对象。我的印象是，如果我移动出版商太 Camel 。事情会得到解决。
我将发布者更改为以下版本。

@EndpointInject(context = "myContext" , uri = "direct:myRoute")
    private ProducerTemplate sendAMyContext;

在我调用方法中

@Override
public MyResponse putMyCall(
        MyRequest myrequest) {

        sendMyContext.sendBody(myrequest);

我的 Camel 路线很简单

<camel:camelContext id="MyContext" autoStartup="true" xmlns="http://camel.apache.org/schema/spring">

    <camel:endpoint id="myQueue" uri="${my.queue.1}" />

        <camel:route>
        <camel:from uri="direct:myRoute"/>
        <camel:to uri="bean:mySendHandler"/>
        <camel:convertBodyTo type="String"></camel:convertBodyTo>
        <camel:to uri="ref:myQueue" />
    </camel:route>

</camel:camelContext>

我添加了将Jaxb对象转换为字符串的处理程序（由于错误）

public class MySendHandler {

 @Handler
 public String myDelivery( MyRequest myRequest) throws ParseException, JAXBException {

         JAXBContext jaxbContext = JAXBContext.newInstance(MyRequest.class);
        Marshaller jaxbMarshaller = jaxbContext.createMarshaller();

        // output pretty printed
        jaxbMarshaller.setProperty(Marshaller.JAXB_FRAGMENT, true);
        java.io.StringWriter sw = new StringWriter();
        jaxbMarshaller.marshal(attributedDeliveryRequest, sw);

     return sw.toString();

  }

还是同样的错误

[SpringAMQPConsumer.SpringAMQPExecutor-1] WARN  org.springframework.amqp.support.converter.JsonMessageConverter (JsonMessageConverter.java:111) - Could not convert incoming message with content-type [text/plain]

我的接收 Camel 路线如下

<camel:route id="processVDelivery">
            <camel:from uri="aVEndpoint" />
            <camel:to uri="bean:myDataHandler" />
        </camel:route>

我补充道

<camel:convertBodyTo type="String"></camel:convertBodyTo>

它给了我一个错误，它不能将它从字符串转换为对象
添加此

<camel:unmarshal></camel:unmarshal>

-------------------------

这个问题的答案是你的mashaller必须是类路径的一部分

-------您也可以使用dataformat自订封送处理器

<camel:dataFormats>

                   <camel:jaxb id="name" contextPath="com.something"/>

    </camel:dataFormats

请确保将jaxb.index文件保存在com.something包中，并使用根级别的Jaxb对象名称

使用带 Spring Boot 的Camel Rest

rest("/authenticate")
                .post()
                .route()
                .setHeader("Content-Type", constant("application/json"))
                .setHeader("Accept", constant("application/json"))
                .setHeader(Exchange.HTTP_METHOD, constant("POST"))
                  .process(exchange -> {
        org.apache.camel.TypeConverter tc = exchange.getContext().getTypeConverter();
String str_value = tc.convertTo(String.class, exchange.getIn().getBody());
             System.err.println(str_value);
              exchange.getOut().setBody(str_value);
      })
                //.removeHeader(Exchange.HTTP_URI)
                .to("http://localhost:8082/authenticate?bridgeEndpoint=true")
                  //.convertBodyTo(DTO.class)
                .log("Boo!")
                .end()
                .endRest();
