@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = TestConfig.class, loader = AnnotationConfigContextLoader.class)
@TestExecutionListeners(listeners = LoadBalancingIntegrationTest.class, mergeMode = TestExecutionListeners.MergeMode.MERGE_WITH_DEFAULTS)
public class LoadBalancingIntegrationTest extends AbstractTestExecutionListener{

    //...

    DummyWebAppService[] dummyWebAppControllers = new DummyWebAppService[4];

    int haproxyListeningPort = 8000;

    //DummyWebApp
    @Value("${dummyWebApp.mvnPath}")
    String mavenPath;

    @Value("${dummyWebApp.webAppPath}")
    String webAppPath;

    @Override
    public void beforeTestClass(TestContext testContext) throws Exception {
        dummyWebAppControllers[0] = new DummyWebAppService(mavenPath, webAppPath, 8080);
    }

    //..test cases follow
}

我在测试用例中使用spring依赖注入。我对TestExecutionListeners的执行顺序有疑问。根据{{​​3}},可以通过Ordered接口或@Order注释和this documentation about the ordering of custom TestExecutionListeners指定顺序。但是,在执行此测试类时,beforeTestClass在任何注入之前执行。我甚至放入了mergeMode = TestExecutionListeners.MergeMode.MERGE_WITH_DEFAULTS,因此不会错过任何默认TestExecutionListeners。在beforeTestClass注释掉时,注入正常执行。

我的问题是,为什么我的beforeTestClass首先执行?我可以告诉它在注射后执行吗?

不确定它是否是正确的修复程序,但它足以用于我的用例,即在beforeTestClass之前注入bean。只需通过写作强制它自动装配即可 @Override public void beforeTestClass(TestContext testContext) throws Exception { testContext.getApplicationContext().getAutowireCapableBeanFactory().autowireBean(this); dummyWebAppControllers[0] = new DummyWebAppService(mavenPath, webAppPath, 8080); }

似乎有点hacky强迫autowire,但嘿我的问题解决了
