我在将Spring-cloud-contract与我的服务集成在消费者方面存在问题。在我的服务中，我使用已经假装（调用其他服务）和zuul（用于路由）来自spring-cloud。当我尝试运行使用@AutoConfigureStubRunner注释的测试时，会出现问题。这是我的简单课程：

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureStubRunner(ids = {"group:artifact:+:stubs:8080"}, workOffline = true)
public class WithContractTests {
    @Test
    public void test() {}
}

在输出中，我可以看到存根已正确启动：

o.s.c.c.stubrunner.StubRunnerExecutor    : All stubs are now running RunningStubs [namesAndPorts={group:artifact:1.0.0-SNAPSHOT:stubs=8080}]

然后在创建spring上下文时出现此错误：

有趣的是，spring-cloud-contract示例中出现了同样的错误： 将Zuul添加到项目后https://github.com/spring-cloud/spring-cloud-contract/tree/master/samples/standalone/dsl/http-client。通过添加Zuul我的意思是添加 spring-cloud-starter-zuul 作为依赖项和 @EnableZuulProxy 注释。之后，我们可以在执行测试时看到以下错误：

将Zuul与Stub runner一起使用时，是否需要一些额外的配置？

1 个答案:

答案 0 :(得分：0)

哦，小伙子，这是我的错。你能在合同中提出问题吗？到目前为止，您必须要覆盖现有的类，它不会将服务器添加到从委托返回的列表中，而是创建添加服务器的新列表。我没有对Zuul进行测试：/

这里已经修复了（希望如此） - https://github.com/spring-cloud/spring-cloud-contract/issues/82
