Spring Boot 2.7.1与Spring Cloud发行版不兼容报错排查

在Gradle项目中搭配使用Spring Boot 2.7.1、Spring Cloud 2021.0.3、Spring Contract 3.1.3时，测试阶段加载Spring上下文抛出Bean创建异常，核心错误为Spring Cloud内置的版本兼容性校验不通过，提示Spring Boot 2.7.1与当前使用的Spring Cloud发行版不匹配，给出的临时处理提示为更换Spring Boot为2.6.x版本，或设置配置项关闭兼容性校验。
项目当前引入的Spring Cloud相关依赖如下：

• org.springframework.cloud:spring-cloud-contract-gradle-plugin:3.1.3
• org.springframework.cloud:spring-cloud-dependencies:2021.0.3

方案1：对齐官方兼容版本（生产环境推荐） #

该报错的根本原因是版本不匹配：Spring Cloud 2021.0.3属于Jubilee发行序列，官方适配的Spring Boot版本范围为2.6.x，无法原生兼容Spring Boot 2.7.1。可任选一种版本调整方式处理：

• 保留当前Spring Cloud、Spring Cloud Contract版本不变，将Spring Boot版本降级到2.6.x系列的稳定版本即可
• 保留当前Spring Boot 2.7.1版本不变，将Spring Cloud升级到原生支持2.7.x版本的发行版，同步将Spring Cloud Contract升级到对应适配版本，确保三个组件版本均落在官方兼容范围内。

方案2：临时关闭兼容性校验（仅用于本地调试，不推荐生产使用） #

如果暂时不需要调整依赖版本，可通过配置跳过版本校验流程，根据项目场景选择对应配置方式：

1. 全局配置（application.yml）：

spring:
  cloud:
    compatibility-verifier:
      enabled: false

2. 全局配置（application.properties）：

spring.cloud.compatibility-verifier.enabled=false

3. 测试类临时配置：

@SpringBootTest(properties = "spring.cloud.compatibility-verifier.enabled=false")

注意：关闭校验仅会跳过启动时的版本检查逻辑，不会修复不同版本间实际存在的API不兼容、逻辑差异等问题。如果后续运行中出现类不存在、方法签名不匹配等报错，仍需通过版本对齐的方式解决。
