为什么我不能用常规将实现作为参数传递给采用其接口的方法？

Question

我正在

groovy.lang.MissingMethodException: No signature of method: org.apache.camel.builder.AdviceWithBuilder.replaceFromWith() is applicable for argument types: (org.apache.camel.component.direct.DirectEndpoint) values: [direct://start]

该方法的签名是AdviceWithBuilder.replaceFromWith(Endpoint ep)我传入了实现Endpoint的DirectEndpoint ，我试图将其强制到Endpoint

@Test
void testSubmitDocument() {
    final Endpoint endpoint = context.getEndpoint("direct:start",Endpoint.class)
    camelContext.getRouteDefinitions().get(0).adviceWith(camelContext, 
         new AdviceWithRouteBuilder (){
             void configure(){
                 weaveById("bar").replaceFromWith(endpoint)
             }
        } 

    )
    }

Answer 1

因为AdviceWithRouteBuilder.weaveById（String pattern）返回AdviceWithBuilder ，但它没有replaceFromWith方法。
