我正在尝试拦截一条消息以跳过 Http 请求并继续我的路线。下面是您可以复制/粘贴来试用的课程。

使用 camel-test、camel-core、camel-http4 2.10.2 和 httpclient-osgi、httpcore-osgi 4.2.2

这是代码：

import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.apache.camel.builder.AdviceWithRouteBuilder;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.test.junit4.CamelTestSupport;
import org.junit.Test;

public class IsUseAdviceWithJUnit4Test extends CamelTestSupport {

    private String providerEndPointURI = "http://stackoverflow.com";
    private String timerEndPointURI = "timer://myTimer";
    private String mockEndPointURI = "mock:myMock";
    private String directEndPointURI = "direct:myDirect";
    private boolean messageIntercepted;

    @Override
    protected RouteBuilder createRouteBuilder() throws Exception {

        return new RouteBuilder() {
            @Override
            public void configure() throws Exception {

                from(timerEndPointURI + "?fixedRate=true&delay=1000&period=1000")
                        .to(providerEndPointURI + "?throwExceptionOnFailure=false")
                        .to(mockEndPointURI);
            }
        };
    }

    @Test
    public void testIsUseAdviceWith() throws Exception {

        messageIntercepted = false;

        context.getRouteDefinitions().get(0).adviceWith(context, new AdviceWithRouteBuilder() {
            @Override
            public void configure() throws Exception {

                replaceFromWith(directEndPointURI);

                mockEndpoints();

                interceptSendToEndpoint(providerEndPointURI)
                        .skipSendToOriginalEndpoint()
                        .process(new Processor() {
                            @Override
                            public void process(Exchange exchange) throws Exception {
                                messageIntercepted = true;
                                System.out.println("INTERCEPTED");
                            }
                        });
            }
        });

        // we must manually start when we are done with all the advice with
        context.start();

        getMockEndpoint(mockEndPointURI).expectedMessageCount(1);

        template.sendBody(directEndPointURI, "a trigger");

        assertMockEndpointsSatisfied();

        assertEquals(true, messageIntercepted);

        assertNotNull(context.hasEndpoint(directEndPointURI));
        assertNotNull(context.hasEndpoint("mock:" + directEndPointURI));

        assertNotNull(context.hasEndpoint(mockEndPointURI));
    }

    @Override
    public boolean isUseAdviceWith() {
        return true;
    }

    @Override
    public boolean isUseRouteBuilder() {
        return true;
    }
}

感谢您的帮助 ！
