我尝试 clean install 项目，以便 spring-cloud-contract 生成我的测试类。 BaseClass 如下：

    @RunWith(SpringRunner.class)
    @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.MOCK, classes = PricingServiceApplication.class)
    @DirtiesContext
    public class BaseClass {

    @Autowired
    private RateChartController rateChartController;

    @Before
    public void setup() {
        StandaloneMockMvcBuilder standaloneMockMvcBuilder = MockMvcBuilders
            .standaloneSetup(rateChartController);
        RestAssuredMockMvc.standaloneSetup(standaloneMockMvcBuilder);
    }
}

我偶然发现的异常如下：

如果你能帮助我解决这个问题，我将不胜感激。

Answer 1

看起来您在默认路径 (src/test/resources/contracts) 下没有合同，这导致无法复制到目标，从而导致异常。

Answer 2

经过几天努力寻找解决方案后，我得出的结论是我的 Spring 引导版本 (1.5.10) 与 Spring Cloud Contract Verifier (2.1.1) 不兼容), 虽然我没有在网上找到任何兼容性矩阵，它只是基于我在这种情况下的实验。通过迁移到 Spring Boot 2.1.x 问题已解决，并且运行良好。非常感谢 Josh Long 和 Marcin Grzejszczak 在会议上关于 Spring Contract 的介绍。

Answer 3

要对问题应用临时解决方案，只需在 (src/test/resources) 下创建一个文件夹 contracts。创建后应该是 (src/test/resources/contracts) 。但是您应该实施合同验证程序来相应地满足您的端点。希望对您有所帮助。
