您可以将toD与动态URI一起使用，动态URI从消息正文、标头或交换属性中获取版本、源和ID。您还可以使用property-placeholders定义主机、端口和其他配置。
由于REST端点都使用相同的结构，因此您可以更改版本、源和id，并对大多数（如果不是所有）REST API调用使用相同的URI。

范例：

public class ExampleTest extends CamelTestSupport {

    static final String API_DYNAMIC_URI = "https://{{api.uri}}:{{api.port}}/{{api.version}}" 
        + "/${exchangeProperty.source}/${exchangeProperty.id}"
        + "?disableStreamCache=true";

    @Test
    public void exampleTest() throws Exception {

        context.adviceWith(context.getRouteDefinition("exampleRoute"), 
            new AdviceWithRouteBuilder(){

            @Override
            public void configure() throws Exception {

                weaveById("apiEndpoint")
                    .replace()
                    .toD("mock:${exchangeProperty.source}/${exchangeProperty.id}")
                    .setBody().simple("Source: ${exchangeProperty.source} id: ${exchangeProperty.id}");
            } 
        });        

        Map<String, Object> body1 = new HashMap<>();
        body1.put("source", "source1");
        body1.put("id", "A");

        Map<String, Object> body2 = new HashMap<>();
        body2.put("source", "source2");
        body2.put("id", "B");

        MockEndpoint source1MockEndpoint = getMockEndpoint("mock:source1/A");
        source1MockEndpoint.expectedMessageCount(1);

        MockEndpoint source2MockEndpoint = getMockEndpoint("mock:source2/B");
        source2MockEndpoint.expectedMessageCount(2);

        startCamelContext();
        template.sendBody("direct:start", body1);

        template.sendBody("direct:start", body2);
        template.sendBody("direct:start", body2);

        source1MockEndpoint.assertIsSatisfied();
        source2MockEndpoint.assertIsSatisfied();
    }

                    .toD(API_DYNAMIC_URI).id("apiEndpoint")
                    .log("Received: ${body}");
            }
        };
