spring cloud 合同验证器测试失败，spring cloud bus

Posted 2023-02-16

技术标签:

【中文标题】spring cloud 合同验证器测试失败，spring cloud bus【英文标题】：spring cloud contract verifier test fails with spring cloud bus 【发布时间】：2021-02-21 13:00:39 【问题描述】：

我使用 spring-cloud-contract 来测试 2 个应用程序之间的 rabbitmq 消息。这里创建了一个简单的应用程序。 https://github.com/winster/contract-test-sample（免费龙目岛）

但是，如果我将 spring-cloud-starter-bus-amqp 添加到生产者依赖项（无论是否替换 spring-boot-starter-amqp），生产者端自动生成的 ContractVerifierTest 将失败并出现以下跟踪。

有人可以指导我如何解决这个问题吗？

【问题讨论】：

【参考方案1】：

问题在于验证者使用的是stream 实现而不是amqp。在org.springframework.cloud.contract.verifier.messaging 内部，有不同的MessageVerifier 实现可用。不知何故使用了没有明确启用stream。因此，上述问题的解决方案是在test/resources/application.properties中添加以下内容

stubrunner.stream.enabled=false

还有stubrunner.amqp.enabled=true
