java - Camel onException() 未触发

Question

我正在尝试测试我的 onException 代码，但它在单元测试下没有触发。我可以 doCatch() 路由中的异常，但否则它只是传递回单元测试代码。我将其归结为硬编码的 throwException() 和 log() 语句，但没有运气。使用 Camel 2.17.1。

有什么想法吗？

路线:

@Component
public class BookingSummaryRouteBuilder extends RouteBuilder {
[...]
@Override
public void configure() throws Exception {

    errorHandler(killSwitchErrorHandlerBuilder);

    onException(Exception.class)
            .description("We can get here functional exception and we mustn't send any mail in this case.")
            .log(LoggingLevel.INFO, "blahblah")
            .handled(true)
            /*.filter().method(exceptionAnalyserService, "isFunctionalException(${exception})")
                .to(DIRECT_FUNCTIONAL_EXCEPTION)
                .stop()
            //not functional exception*/
            .to("direct:dlq.fatal-error")
    ;

    from("activemq:queue:routemod.spot-booking.summary?concurrentConsumers=1")
            .routeId(BOOKING_SUMMARY_ENTRY_ROUTE)
            .description("Requests and receives a booking summary report")
            .log(LoggingLevel.INFO, "blah")
            .throwException(new ConfigurationException("something"))
    ;

单元测试:

public class BookingSummaryRequestRouteTest extends CamelTestSupport {
[...]
private static final String MOCKED_ENTRYPOINT = "direct:mock-entry";

//under test
@InjectMocks
private BookingSummaryRouteBuilder builder;
[...]
@Override
public boolean isUseAdviceWith() {
    return true;
}

@Before
public void setUpAdviceWith() throws Exception {

    AdviceWithRouteBuilder adviceWithConfig = new AdviceWithRouteBuilder() {
        @Override
        public void configure() throws Exception {
            replaceFromWith(MOCKED_ENTRYPOINT);
            interceptSendToEndpoint("tofalink:dummy")
                    .skipSendToOriginalEndpoint()
                    .to(toFalink);
            }
    };

    context.getRouteDefinition(builder.BOOKING_SUMMARY_ENTRY_ROUTE).adviceWith(context, adviceWithConfig);
    context.start();
}


@Override
protected RouteBuilder createRouteBuilder() throws Exception {
    MockitoAnnotations.initMocks(this);

    builder.setDiffsEndpoint(diffsEndpoint);
    builder.setMainframeFacxml(mainframeFacxml);

    return builder;
}

/**
 * No agency found
 */
@Test
public void thatGeneralExceptionRouteInvokedWhenThereIsNoAgency() throws InterruptedException {
    deadLetterChannel.expectedMessageCount(1);
    diffsEndpoint.expectedMessageCount(0);
    doThrow(new ConfigurationException("test"))
            .when(agencyFalinkController).loadByAlphaID(any());

    template.sendBodyAndHeader(MOCKED_ENTRYPOINT, BSH_ID, "scheduleRevisionId", SCHEDULE_REVISION_ID);


    verifyZeroInteractions(killSwitchErrorHandlerBuilder);
    diffsEndpoint.assertIsSatisfied();
    deadLetterChannel.assertIsSatisfied();

}

Answer 1

啊，我在这方面取得了一些进展。问题似乎出在我的 errorHandlerBuilder 上。我用基本的loggingErrorHandler()替换了killswitch，现在会触发onException日志语句。

我的killSwitchErrorHandlerBuilder是一个@Mock，我没有对其进行编程以返回ErrorHandler - 因为我不希望它在此测试中被触发。但我猜如果它返回 null，它就会破坏上下文。

更新通过在 RouteBuilder 中设置 DefaultErrorHandlerBuilder 而不是模拟来修复。
