Spring XD集成测试失败，“Path必须以/ character开头”

Question

我一直在寻找一种在Spring XD中正确测试自定义模块的方法，所以我一直在尝试模仿how Spring Xd itself tests spark processors。但是，无论我如何使用SingleNodeApplication进行配置，我仍然会收到以下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jobsController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.xd.dirt.server.admin.deployment.DeploymentMessagePublisher org.springframework.xd.dirt.rest.XDController.deploymentMessagePublisher; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'deploymentMessageProducer' defined in class org.springframework.xd.dirt.server.admin.deployment.zk.DeploymentConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.xd.dirt.server.admin.deployment.zk.ZKDeploymentMessagePublisher]: Factory method 'deploymentMessageProducer' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'deploymentQueue' defined in class org.springframework.xd.dirt.server.admin.deployment.zk.DeploymentConfiguration: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Path must start with / character

我得到它无法自动装配jobsController，但它总是由于某些（zookeeper？）路径不以/开头。我错过了一些明显的东西吗这里引用的是我的@BeforeClass方法导致一切都失败：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration
public class RakeExtractorProcessorXdTest {

    private static SingleNodeApplication application;

    private static SingleNodeIntegrationTestSupport integrationSupport;

    // This dies
    @BeforeClass 
    public static void setUp() {
        application = new SingleNodeApplication().run("--transport", "local");
        integrationSupport = new SingleNodeIntegrationTestSupport(application);
        integrationSupport.addModuleRegistry(new SingletonModuleRegistry(ModuleType.processor,
            "rake-extractor"));
    }
}

问题是我的项目中没有必要的测试依赖项来运行$start_date->copy()->addDays($tier->duration_days); 实例。通过将SingleNodeApplication插件添加到gradle builds中解决了这个问题。

我们实际上并没有引入太多的Spring XD依赖项，因为我们将它作为docker容器部署，并根据需要在Dockerfile中添加我们的自定义模块。

有一些插件冲突。 spring-xd-module插件看起来像wrapper of Spring Boot and propdeps和uses old versions，与普通的spring-xd-module插件（版本为1.4.1，在spring-boot中发生冲突） 1.2.3）和spring-xd-module插件。通过重组项目层次结构并将所有自定义XD模块放入其自己的gradle子项目中来解决此问题。
