spring cloud contract http实例

微服务很多时，服务之前相互调用，接口参数的一致性要变得很难维护。
spring cloud>spring cloud contract 提供了测试接口一致性的方法。

一项目配置

plugins {id "groovy"id "org.springframework.cloud.contract" version "4.0.5"id "maven-publish"
}String contractVersion = "1.0.0-contract-SNAPSHOT"ext {set('springCloudVersion', "2022.0.5")set('groovyVersion', "4.0.20")set('contractVersion', "4.0.5")set('streamVersion', "4.0.5")
}contracts {testMode = 'MockMvc'deleteStubsAfterTest = truebaseClassForTests = "com.leve.${artifactId}.ContractTestBase"generatedTestJavaSourcesDir = project.file("src/contractTest/contract")
}dependencies {testImplementation("org.apache.groovy:groovy-all:${groovyVersion}")testImplementation("org.springframework.cloud:spring-cloud-starter-contract-verifier")testImplementation("org.springframework.cloud:spring-cloud-starter-contract-stub-runner")
}dependencyManagement {imports {mavenBom("org.springframework.cloud:spring-cloud-dependencies:${property("springCloudVersion")}")mavenBom "org.springframework.cloud:spring-cloud-contract-dependencies:${property("contractVersion")}"mavenBom ("org.springframework.cloud:spring-cloud-stream-dependencies:${property("streamVersion")}")}
}publishing {publications {maven(MavenPublication) {artifact(tasks.named('verifierStubsJar'))}// 如果项目名称带有横杠的，比如说auth-ghost，那么需要像下面这样去掉横杠，不然openfign404// maven.artifactId = "authghost"}repositories {maven {url = uri("https://nexus.111.com/repository/leve-maven/")version = contractVersioncredentials {username = nexusUsernamepassword = nexusPassword}allowInsecureProtocol = false}}
}

二基类

公共基类，需要注意基类所在的路径，可以修改配置指定基类的名称和路径。

 
/*** ContractTestBase*/
@SpringBootTest(properties = {"spring.cloud.function.definition=",
})
@AutoConfigureStubRunner
public class ContractTestBase{@Autowiredprivate WebApplicationContext applicationContext;@MockBeanprivate UserInfoService userInfoService;@BeforeEachpublic void setUp() {RestAssuredMockMvc.webAppContextSetup(applicationContext);}}

三消费端配置

ids看你需要哪些服务，自行增改。版本号可以不要，会拉取最新的。

stubrunner:ids:- "com.test:user"- "com.test:ghost"repositoryRoot: https://nexus.test.com/repository/leve-maven/stubsMode: REMOTE

在测试类上面使用 @AutoConfigureStubRunner

四运行测试

User服务调用 ghost服务的接口

4.1 生产端

在ghost服务按照上面的配置，写好contract.yml文件，构建测试通过后，然后publish到nexus上面

4.2 消费端

bootstrap.yml文件添加对应的生产端服务id

然后再对应的测试类上面添加 @AutoConfigureStubRunner

方法中通过openfeign调用ghost服务
