Question

我刚刚将spring boot升级到2.1.0.RELEASE，并将spring cloud stream升级到了Greenwich.SR1。

我有一个集成测试，可以自动装配MessageCollector，但是由于在KafkaBinderConfiguration中已经创建了绑定程序，因此无法加载上下文。

有一个TestSupportBinderConfiguration类，它创建一个测试绑定器bean，但由于其签名而没有发生：

@Configuration
@ConditionalOnMissingBean(Binder.class)
public class TestSupportBinderConfiguration {}

有什么想法吗？
