Spring Cloud 生產(chǎn)者公約

在生產(chǎn)者端，您必須在插件配置中添加兩個(gè)其他依賴項(xiàng)。一個(gè)是Spring Cloud Contract Pact支持，另一個(gè)是您使用的當(dāng)前Pact版本。

Maven. 

<plugin>
	<groupId>org.springframework.cloud</groupId>
	<artifactId>spring-cloud-contract-maven-plugin</artifactId>
	<version>${spring-cloud-contract.version}</version>
	<extensions>true</extensions>
	<configuration>
		<packageWithBaseClasses>com.example.fraud</packageWithBaseClasses>
	</configuration>
	<dependencies>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-contract-pact</artifactId>
			<version>${spring-cloud-contract.version}</version>
		</dependency>
	</dependencies>
</plugin>

Gradle. 

classpath "org.springframework.cloud:spring-cloud-contract-pact:${findProperty('verifierVersion') ?: verifierVersion}"

當(dāng)您執(zhí)行應(yīng)用程序的構(gòu)建時(shí)，將生成一個(gè)測(cè)試。生成的測(cè)試可能如下：

@Test
public void validate_shouldMarkClientAsFraud() throws Exception {
	// given:
		MockMvcRequestSpecification request = given()
				.header("Content-Type", "application/vnd.fraud.v1+json")
				.body("{\"clientId\":\"1234567890\",\"loanAmount\":99999}");

	// when:
		ResponseOptions response = given().spec(request)
				.put("/fraudcheck");

	// then:
		assertThat(response.statusCode()).isEqualTo(200);
		assertThat(response.header("Content-Type")).matches("application/vnd\\.fraud\\.v1\\+json.*");
	// and:
		DocumentContext parsedJson = JsonPath.parse(response.getBody().asString());
		assertThatJson(parsedJson).field("['rejectionReason']").isEqualTo("Amount too high");
	// and:
		assertThat(parsedJson.read("$.fraudCheckStatus", String.class)).matches("FRAUD");
}

相應(yīng)的生成的存根可能如下：

{
  "id" : "996ae5ae-6834-4db6-8fac-358ca187ab62",
  "uuid" : "996ae5ae-6834-4db6-8fac-358ca187ab62",
  "request" : {
    "url" : "/fraudcheck",
    "method" : "PUT",
    "headers" : {
      "Content-Type" : {
        "matches" : "application/vnd\\.fraud\\.v1\\+json.*"
      }
    },
    "bodyPatterns" : [ {
      "matchesJsonPath" : "$[?(@.['loanAmount'] == 99999)]"
    }, {
      "matchesJsonPath" : "$[?(@.clientId =~ /([0-9]{10})/)]"
    } ]
  },
  "response" : {
    "status" : 200,
    "body" : "{\"fraudCheckStatus\":\"FRAUD\",\"rejectionReason\":\"Amount too high\"}",
    "headers" : {
      "Content-Type" : "application/vnd.fraud.v1+json;charset=UTF-8"
    },
    "transformers" : [ "response-template" ]
  },
}
