SpringCloud Stub Runner与Spring

设置Stub Runner项目的Spring配置。

通过在配置文件中提供存根列表，Stub Runner会自动下载并在WireMock中注册所选存根。

如果要查找存根依赖项的URL，可以自动装配StubFinder接口，并使用如下所示的方法：

@ContextConfiguration(classes = Config, loader = SpringBootContextLoader)
@SpringBootTest(properties = [" stubrunner.cloud.enabled=false",
		'foo=${stubrunner.runningstubs.fraudDetectionServer.port}',
		'fooWithGroup=${stubrunner.runningstubs.org.springframework.cloud.contract.verifier.stubs.fraudDetectionServer.port}'])
@AutoConfigureStubRunner(mappingsOutputFolder = "target/outputmappings/",
		httpServerStubConfigurer = HttpsForFraudDetection)
@ActiveProfiles("test")
class StubRunnerConfigurationSpec extends Specification {

	@Autowired
	StubFinder stubFinder
	@Autowired
	Environment environment
	@StubRunnerPort("fraudDetectionServer")
	int fraudDetectionServerPort
	@StubRunnerPort("org.springframework.cloud.contract.verifier.stubs:fraudDetectionServer")
	int fraudDetectionServerPortWithGroupId
	@Value('${foo}')
	Integer foo

	@BeforeClass
	@AfterClass
	void setupProps() {
		System.clearProperty("stubrunner.repository.root")
		System.clearProperty("stubrunner.classifier")
		WireMockHttpServerStubAccessor.clear()
	}

	def 'should mark all ports as random'() {
		expect:
			WireMockHttpServerStubAccessor.everyPortRandom()
	}

	def 'should start WireMock servers'() {
		expect: 'WireMocks are running'
			stubFinder.findStubUrl('org.springframework.cloud.contract.verifier.stubs', 'loanIssuance') != null
			stubFinder.findStubUrl('loanIssuance') != null
			stubFinder.findStubUrl('loanIssuance') == stubFinder.findStubUrl('org.springframework.cloud.contract.verifier.stubs', 'loanIssuance')
			stubFinder.findStubUrl('loanIssuance') == stubFinder.findStubUrl('org.springframework.cloud.contract.verifier.stubs:loanIssuance')
			stubFinder.findStubUrl('org.springframework.cloud.contract.verifier.stubs:loanIssuance:0.0.1-SNAPSHOT') == stubFinder.findStubUrl('org.springframework.cloud.contract.verifier.stubs:loanIssuance:0.0.1-SNAPSHOT:stubs')
			stubFinder.findStubUrl('org.springframework.cloud.contract.verifier.stubs:fraudDetectionServer') != null
		and:
			stubFinder.findAllRunningStubs().isPresent('loanIssuance')
			stubFinder.findAllRunningStubs().isPresent('org.springframework.cloud.contract.verifier.stubs', 'fraudDetectionServer')
			stubFinder.findAllRunningStubs().isPresent('org.springframework.cloud.contract.verifier.stubs:fraudDetectionServer')
		and: 'Stubs were registered'
			"${stubFinder.findStubUrl('loanIssuance').toString()}/name".toURL().text == 'loanIssuance'
			"${stubFinder.findStubUrl('fraudDetectionServer').toString()}/name".toURL().text == 'fraudDetectionServer'
		and: 'Fraud Detection is an HTTPS endpoint'
			stubFinder.findStubUrl('fraudDetectionServer').toString().startsWith("https")
	}

	def 'should throw an exception when stub is not found'() {
		when:
			stubFinder.findStubUrl('nonExistingService')
		then:
			thrown(StubNotFoundException)
		when:
			stubFinder.findStubUrl('nonExistingGroupId', 'nonExistingArtifactId')
		then:
			thrown(StubNotFoundException)
	}

	def 'should register started servers as environment variables'() {
		expect:
			environment.getProperty("stubrunner.runningstubs.loanIssuance.port") != null
			stubFinder.findAllRunningStubs().getPort("loanIssuance") == (environment.getProperty("stubrunner.runningstubs.loanIssuance.port") as Integer)
		and:
			environment.getProperty("stubrunner.runningstubs.fraudDetectionServer.port") != null
			stubFinder.findAllRunningStubs().getPort("fraudDetectionServer") == (environment.getProperty("stubrunner.runningstubs.fraudDetectionServer.port") as Integer)
		and:
			environment.getProperty("stubrunner.runningstubs.fraudDetectionServer.port") != null
			stubFinder.findAllRunningStubs().getPort("fraudDetectionServer") == (environment.getProperty("stubrunner.runningstubs.org.springframework.cloud.contract.verifier.stubs.fraudDetectionServer.port") as Integer)
	}

	def 'should be able to interpolate a running stub in the passed test property'() {
		given:
			int fraudPort = stubFinder.findAllRunningStubs().getPort("fraudDetectionServer")
		expect:
			fraudPort > 0
			environment.getProperty("foo", Integer) == fraudPort
			environment.getProperty("fooWithGroup", Integer) == fraudPort
			foo == fraudPort
	}

	@Issue("#573")
	def 'should be able to retrieve the port of a running stub via an annotation'() {
		given:
			int fraudPort = stubFinder.findAllRunningStubs().getPort("fraudDetectionServer")
		expect:
			fraudPort > 0
			fraudDetectionServerPort == fraudPort
			fraudDetectionServerPortWithGroupId == fraudPort
	}

	def 'should dump all mappings to a file'() {
		when:
			def url = stubFinder.findStubUrl("fraudDetectionServer")
		then:
			new File("target/outputmappings/", "fraudDetectionServer_${url.port}").exists()
	}

	@Configuration
	@EnableAutoConfiguration
	static class Config {}

	@CompileStatic
	static class HttpsForFraudDetection extends WireMockHttpServerStubConfigurer {

		private static final Log log = LogFactory.getLog(HttpsForFraudDetection)

		@Override
		WireMockConfiguration configure(WireMockConfiguration httpStubConfiguration, HttpServerStubConfiguration httpServerStubConfiguration) {
			if (httpServerStubConfiguration.stubConfiguration.artifactId == "fraudDetectionServer") {
				int httpsPort = SocketUtils.findAvailableTcpPort()
				log.info("Will set HTTPs port [" + httpsPort + "] for fraud detection server")
				return httpStubConfiguration
						.httpsPort(httpsPort)
			}
			return httpStubConfiguration
		}
	}
}

对于以下配置文件：

stubrunner:
  repositoryRoot: classpath:m2repo/repository/
  ids:
    - org.springframework.cloud.contract.verifier.stubs:loanIssuance
    - org.springframework.cloud.contract.verifier.stubs:fraudDetectionServer
    - org.springframework.cloud.contract.verifier.stubs:bootService
  stubs-mode: remote

除了使用属性外，还可以使用@AutoConfigureStubRunner内部的属性。您可以在下面找到通过在注释上设置值来获得相同结果的示例。

@AutoConfigureStubRunner(
		ids = ["org.springframework.cloud.contract.verifier.stubs:loanIssuance",
				"org.springframework.cloud.contract.verifier.stubs:fraudDetectionServer",
				"org.springframework.cloud.contract.verifier.stubs:bootService"],
		stubsMode = StubRunnerProperties.StubsMode.REMOTE,
		repositoryRoot = "classpath:m2repo/repository/")

Stub Runner Spring以下列方式为每个已注册的WireMock服务器注册环境变量。Stub Runner ID com.example:foo，com.example:bar的示例。

您可以在代码中引用该代码。

您也可以使用@StubRunnerPort批注注入正在运行的存根的端口。注释的值可以是groupid:artifactid，也可以只是artifactid。Stub Runner ID com.example:foo，com.example:bar的示例。

@StubRunnerPort("foo")
int fooPort;
@StubRunnerPort("com.example:bar")
int barPort;
