Camel 测试 - 无法创建路由...因为必须在以下位置指定 ref：进程

Question

我写了这条骆驼路线：

@Component
public class FirstRoute extends RouteBuilder {

    private static final String DIRECT_ENDPOINT = "direct:test_direct";
    private static final String HTTP_ENDPOINT = "http:test_http";

    @Autowired
    private URIProcessor uriProcessor;

    @Override
    public void configure() throws Exception {
        restConfiguration().component("servlet").bindingMode(RestBindingMode.json);

        rest("/doTest/").post("/{comp}").to(DIRECT_ENDPOINT);

        test();
    }

    public void test() {        
        from(DIRECT_ENDPOINT).routeId("route_rest")
        .marshal().json(JsonLibrary.Jackson)
        .process(uriProcessor)
        .to(HTTP_ENDPOINT).unmarshal().json(JsonLibrary.Jackson, TestDto.class);

    }


}

效果很好。

我想为这条路线编写一个测试类，所以在测试类中我写道：

    @Override
    protected RouteBuilder createRouteBuilder() throws Exception {
        return new FirstRoute();

但是当我运行测试时出现错误。

这是错误日志：

org.apache.camel.FailedToCreateRouteException: Failed to create route route_rest at: >>> process[Processor@0x0] <<< in route: Route(route_rest)[[From[direct:testEsenzioneReddito]] -> [Ma... because of ref must be specified on: process[Processor@0x0]
    ...
Caused by: java.lang.IllegalArgumentException: ref must be specified on: process[Processor@0x0]
... 42 more

我不知道这可能是什么，有人有任何建议吗？谢谢
