使用 Spring Boot 1.5.x 的 Spring Cloud 合约出错

Question

我正在尝试为 1.5.X 上的 Spring Boot 应用程序实现 Spring Cloud 合约。

我添加了以下依赖项：

<plugin>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-contract-maven-plugin</artifactId>
    <version>${spring-cloud-contract.version}</version>
    <extensions>true</extensions>
    <configuration>
        <packageWithBaseClasses>com.example</packageWithBaseClasses>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-contract-verifier</artifactId>
            <version>${spring-cloud-contract.version}</version>
        </dependency>
        <dependency>
           <groupId>io.rest-assured</groupId>
           <artifactId>rest-assured</artifactId>
           <version>3.0.2</version>
           <scope>compile</scope>
        </dependency>
        <dependency>
           <groupId>io.rest-assured</groupId>
           <artifactId>spring-mock-mvc</artifactId>
           <version>3.0.2</version>
           <scope>compile</scope>
        </dependency>
    </dependencies>
</plugin>

<dependencies>
    <!-- all dependencies -->
    <!-- you can exclude rest-assured from spring-cloud-contract-verifier -->
    <dependency>
       <groupId>io.rest-assured</groupId>
       <artifactId>rest-assured</artifactId>
       <version>3.0.2</version>
       <scope>test</scope>
    </dependency>
    <dependency>
       <groupId>io.rest-assured</groupId>
       <artifactId>spring-mock-mvc</artifactId>
       <version>3.0.2</version>
       <scope>test</scope>
    </dependency>
</dependencies>

我创建了如下的基类：

BaseClass.java

@RunWith(SpringRunner.class) 
@SpringBootTest(classes=MySpringBootApplication.class)
public abstract class BaseClass {
  @Autowired
  MyController myController;

  //Mock Dependencies
  RestAssuredMockMVC.standaloneSetup(myController)
}

我可以看到测试是由 spring 合同按预期生成的（基于 yml 合同），并且我的构建失败并出现以下错误：

    java.lang.noclassdeffounderror org/springframework/boot/context/properties/bind/binder
       at org.springframework.cloud.function.compiler.config.FunctionProxyApplicationListener.bind(FunctionProxyApplicationListener.java:120)

.......
Caused by: java.lang.ClassNotFoundException: org.springframework.boot.context.properties.bind.Binder

您使用的 Spring Cloud 合约版本与该版本的 Spring Boot 不兼容。这就是为什么你会得到 class not found 异常
