在 Spring Integration 中模拟 MessageHandler 时出现 java.lang.NoSuchMethodError

Question

我有一个简单的 Spring Integration 配置

@Configuration
public class FTPIntegration {


@Bean
public MessageChannel outputIntegrationChannel(ErrorHandler errorHandler) {
    return MessageChannels
            .publishSubscribe()
            .errorHandler(errorHandler)
            .get();
}

@Bean
public IntegrationFlow ftpIntegration(ErrorHandler errorHandler, MessageHandler messageHandler) {
    return IntegrationFlows
            .from(outputIntegrationChannel(errorHandler))
            .transform(Transformers.toJson())
            .handle(messageHandler)
            .get();
}
}

我想准备一些使用 Mockito 来模拟、监视 MessageHandler 和 ErrorHandler 的集成测试。所以这就是我想在测试配置中替换它们的原因。

@Profile("test")
@EnableIntegration
@Configuration
@Import(value = FTPIntegration.class)
public class TestConf {

@Bean
@Primary
public ErrorHandler errorHandler() {
    return mock(ErrorHandler.class);
}

@Bean
@Primary
public MessageHandler messageHandler() {
    return mock(MessageHandler.class);
}
}

并在我的测试课中使用它

@ActiveProfiles("test")
@RunWith(SpringRunner.class)
@SpringBootTest(classes = TestConf.class)
public class FTPIntegrationTest {

@Autowired
@Qualifier("outputIntegrationChannel")
private MessageChannel integrationChannel;
}

但是在初始化时我得到了一个错误

java.lang.NoSuchMethodError: org.mockito.MockingDetails.getMockCreationSettings()Lorg/mockito/mock/MockCreationSettings;

是我的配置有问题还是无法在 Spring Integration 中使用 Mockito 的组件？

当我使用一些简单的方法参考时，例如 在MessageError和MessageHandler 中返回 log::error 或 log::info时，它可以正常工作。

我也尝试使用 MockIntegration.mockMessageHandler(); 但结果是相同的（例外），因为它在下面使用了 Mockito 的模拟。

Mockito 是 1.x 版本，它与 Spring Integration 与 5.x 版本不兼容。将 Mockito 升级到 2.x (2.22.0) 修复了这个问题并与 Spring Integration (5.0.8.RELEASE) 一起使用。
