Question

我试图将spring cloud合约添加到我的jHipster应用程序中。这是一个基本的Spring Boot Micro服务应用程序。我没有为微服务号1生成存根有任何问题，但是当我尝试使用它时，我得到：

org.springframework.cloud.contract.stubrunner.StubNotFoundException：找不到带有符号测试的存根的存根

我使用的是SC-Contract 1.0.1.RELEASE的版本。

jHipster没有使用@SpringBootApplication注释，因此我必须使用@SpringBootTest(classes=...)设置我的上下文。就我而言：

@SpringBootTest(webEnvironment=WebEnvironment.RANDOM_PORT, classes=TestApp.class)

这是TestApp.java：

@ComponentScan
@EnableAutoConfiguration(exclude = { MetricFilterAutoConfiguration.class, MetricRepositoryAutoConfiguration.class })
@EnableConfigurationProperties({ JHipsterProperties.class, LiquibaseProperties.class })
@EnableDiscoveryClient
public class TestApp {

    private static final Logger log = LoggerFactory.getLogger(TestApp.class);

    @Inject
    private Environment env;

    /**
     * Initializes Test.
     * <p>
     * Spring profiles can be configured with a program arguments --spring.profiles.active=your-active-profile
     * <p>
     * You can find more information on how profiles work with JHipster on <a href="http://jhipster.github.io/profiles/">http://jhipster.github.io/profiles/</a>.
     */
    @PostConstruct
    public void initApplication() {
        log.info("Running with Spring profile(s) : {}", Arrays.toString(env.getActiveProfiles()));
        Collection<String> activeProfiles = Arrays.asList(env.getActiveProfiles());
        if (activeProfiles.contains(Constants.SPRING_PROFILE_DEVELOPMENT) && activeProfiles.contains(Constants.SPRING_PROFILE_PRODUCTION)) {
            log.error("You have misconfigured your application! It should not run " +
            "with both the 'dev' and 'prod' profiles at the same time.");
        }
        if (activeProfiles.contains(Constants.SPRING_PROFILE_DEVELOPMENT) && activeProfiles.contains(Constants.SPRING_PROFILE_CLOUD)) {
            log.error("You have misconfigured your application! It should not" +
            "run with both the 'dev' and 'cloud' profiles at the same time.");
        }
    }

    /**
     * Main method, used to run the application.
     *
     * @param args the command line arguments
     * @throws UnknownHostException if the local host name could not be resolved into an address
     */
    public static void main(String[] args) throws UnknownHostException {
        SpringApplication app = new SpringApplication(TestApp.class);
        DefaultProfileUtil.addDefaultProfile(app);
        Environment env = app.run(args).getEnvironment();
        log.info("\n----------------------------------------------------------\n\t" +
            "Application '{}' is running! Access URLs:\n\t" +
            "Local: \t\thttp://localhost:{}\n\t" +
            "External: \thttp://{}:{}\n----------------------------------------------------------",
        env.getProperty("spring.application.name"),
        env.getProperty("server.port"),
        InetAddress.getLocalHost().getHostAddress(),
        env.getProperty("server.port"));

        String configServerStatus = env.getProperty("configserver.status");
        log.info("\n----------------------------------------------------------\n\t" +
    "Config Server: \t{}\n----------------------------------------------------------",
        configServerStatus == null ? "Not found or not setup for this application" : configServerStatus);
    }
}

最后，这是我的Test类（简化）：

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment=WebEnvironment.RANDOM_PORT,classes=TestApp.class)
@AutoConfigureStubRunner(ids = "com.mycompany.myapp:article:+:stubs:8080", workOffline = true)
public class ArticleServiceTests {

    private ArticleService service = new ArticleService();

    @Test
    public void shouldExist(){}

}

感谢您的帮助！

我发现问题出在哪里，但我还不知道如何解决问题。

使用jHipster，我使用的是hazelcast，hazelcast正在使用eureka，eureka正在实现DiscoveryClient接口（eureka类的链接：https://github.com/spring-cloud/spring-cloud-netflix/blob/758ff920fc71d9a2aaf41d1250d3cc5ddd46b870/spring-cloud-netflix-eureka-client/src/main/java/org/springframework/cloud/netflix/eureka/EurekaDiscoveryClient.java），如StubRunnerDiscoveryClient中的SC-Contract。

两个类，具有相同的接口且没有任何访问权限。

加载的第一个是spring.cloud.contract.stubrunner，因此当hazelcast尝试加载时会出现此异常。

所以我编辑了使用DiscoveryClient的当前代码，现在它很好！
