在Springboot 版本是 2.6.6 的情况下，nacos 客户端 依赖的actuator 也需要升级。

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
    <version>2.2.5.RELEASE</version>

<dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-actuator</artifactId>
     <version>2.6.6</version>
</dependency>

Springboot 版本是 2.6.6 的情况下，报下面异常，希望 nacos client 能升级下 springboot 版本。

 java.lang.ClassNotFoundException: org.springframework.boot.actuate.autoconfigure.health.HealthIndicatorAutoConfiguration

官方文档版本支持说明：

2021.x branch: Corresponds to Spring Cloud 2021 & Spring Boot 2.6.x. JDK 1.8 or later versions are supported. 升级你的spring-cloud-alibaba，使用2021.x版本而不是2.2.x版本。
