我尝试过对Apache Camel进行单元测试，我从一个真实的的基本案例开始，我的路径看起来像这样：

public class TestRoute extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        from("jpa:Data").to("jpa:Data").id("testId");
    }
}

现在，以下方法不起作用。我尝试模拟所有端点，但得到的结果是mock://jpa:Data Received message count. Expected: <1> but was: <0>

public class RouteTest extends CamelTestSupport {
    @Override
    @BeforeEach
    public void setUp() throws Exception {
        super.setUp();
    }

    @Override
    protected RoutesBuilder createRouteBuilder() throws Exception {
        return new TestRoute();
    }

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

    @Test
    void testRoute() throws Exception {
        AdviceWith.adviceWith(context, null, false, a -> {
            a.replaceFromWith("direct:start");
            a.mockEndpointsAndSkip("*");
        });
        context.start();
        // The false here makes sure that I get an exception if I'm using a name 
        // of a nonexistent mocked endpoint, so that shouldn't be the problem here
        getMockEndpoint("mock:jpa:Data", false).expectedMessageCount(1);

        var data = getSomeTestData();
        template.sendBody("direct:start", data);
        assertMockEndpointsSatisfied();
    }
}

我发现的一个解决方法是用a.weaveById("testId").replace().to("mock:jpa:Data");替换a.mockEndpointsAndSkip("*");。但是我不确定在这种情况下有什么区别，因为mockEndpointsAndSkip也应该用模拟版本替换所有端点。在真实的场景中手动替换所有端点会有点麻烦。
