java - 为什么我不能在 groovy 中将实现作为参数传递给采用其接口(interface)的方法？

Question

我得到了

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)我路过 DirectEndpoint实现端点我尝试将其强制到端点

@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并且它没有 replaceFromWith 方法。
