spring云数据流与测试中的spring引导数据mongodn冲突

spring spring-boot spring-cloud

spring云数据流与测试中的spring引导数据mongodn冲突,spring,spring-boot,spring-cloud,spring-data-mongodb,spring-cloud-stream,Spring,Spring Boot,Spring Cloud,Spring Data Mongodb,Spring Cloud Stream,我有一个非常简单的junit套件，如下所示： @RunWith(SpringJUnit4ClassRunner.class) @SpringBootTest(classes = MessagingTest.BindingProcess.class, properties = { "server.port=-1" }) @DirtiesContext @DataMongoTest public class MessagingTest { @SpringBootApplication @Enabl

我有一个非常简单的junit套件，如下所示：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = MessagingTest.BindingProcess.class, properties = { "server.port=-1" })
@DirtiesContext
@DataMongoTest
public class MessagingTest {

@SpringBootApplication
@EnableBinding(Source.class)
public static class BindingProcess {
}

@Autowired
private BinderFactory binderFactory;

@Autowired
private MessageCollector messageCollector;

@Test
public void dummyTest() {
    Assert.assertTrue(true);
}
}

并且测试因以下异常而失败：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'service.MessagingTest': Unsatisfied dependency expressed through field 'messageCollector'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.cloud.stream.test.binder.MessageCollector' available: expected at least 1 bean which qualifies as autowire candidate.

但是如果我删除
@DataMongoTest
注释，一切都很好。我不太清楚这件事发生了什么。有人能帮忙吗

@DataMongoTest
禁用自动配置，因此不会拾取测试绑定器配置

要使测试绑定器正常工作，您可以尝试通过以下方式将其自动配置添加到测试中： 

@导入配置（org.springframework.cloud.stream.test.binder.TestSupportBinderAutoConfiguration.class）

使用Spring Cloud Stream Ditmars.SR3，我不知道为什么，但我必须明确声明这些自动配置：

@ImportAutoConfiguration({TestSupportBinderAutoConfiguration.class, MessageCollectorAutoConfiguration.class})
为什么要测试空类，创建它只是为了获取源绑定？您还可以使用TestSupportBinder获取messageCollector的实例
