Spring Cloud Kubernetes 2.0.0 M1（Milestone 1）是 Spring Cloud 官方为适配 Kubernetes 原生能力而发布的**首个 2.x 版本里程碑版
Spring Cloud Kubernetes 2.0.0 M1（Milestone 1）是 Spring Cloud 官方为适配 Kubernetes 原生能力而发布的首个 2.x 版本里程碑版本，于 2022 年初发布（具体为 2022年2月），标志着该项目从 Spring Cloud Commons 集成范式向完全基于 Spring Boot 3 和 Jakarta EE 9+（即jakarta.*命名空间）的现代化重构迈出关键一步。该版本的重要变化包括：
✅核心升级：
- 基于Spring Boot 3.0.0-Mx和Spring Framework 6.0.0-Mx；
- 全面迁移到Jakarta EE 9+ API（如
jakarta.annotation,jakarta.inject），弃用所有javax.*包； - 移除对旧版 Spring Cloud Commons 中
ServiceRegistry/Registration的依赖，转而使用 Spring Boot 3 的ServiceInstanceRegistration抽象；
✅功能演进：
- 重写
KubernetesDiscoveryClient，支持多命名空间服务发现（通过spring.cloud.kubernetes.discovery.namespaces配置）； - 增强 ConfigMap/Secret 的实时监听能力（基于 Informer 机制，降低轮询开销）；
- 初步支持 Spring Cloud LoadBalancer 与 Kubernetes Service 的原生集成（替代 Ribbon）；
- 引入
@ConditionalOnKubernetes等新条件注解，提升环境感知能力；
⚠️注意：
- 此为Milestone 版本（非生产就绪），不建议用于生产环境；
- 与 Spring Cloud 2022.x（即 Kilburn）版本线对齐，不兼容 Spring Boot 2.x / Spring Cloud 2021.x 及更早版本；
- 后续正式版（2.0.0 GA）于 2022年10月随 Spring Cloud 2022.0.0（Kilburn）发布。

Spring Cloud Kubernetes provide Spring Cloud common interface implementations that consume Kubernetes native services. The main objective of the projects provided in this repository is to facilitate the integration of Spring Cloud and Spring Boot applications running inside Kubernetes.

The easiest way to get started is by including the Spring Cloud BOM and then adding spring-cloud-starter-kubernetes-all to your application’s classpath. If you don’t want to include all of the Spring Cloud Kubernetes features you can add individual starters for the features you would like. By default Spring Cloud Kubernetes will enable the kubernetes profile when it detects it is running inside a Kubernetes cluster. You can take advantage of this by creating a kubernetes-application configuration properties for anything specific to Kubernetes you might want to configure. Once the starter is on the classpath the application should behave as any other Spring Cloud application.
