请记得在bootstrap.properties文件中新增配置

spring.cloud.nacos.config.refreshable-dataids=nacos-service.properties,true

 

 后面又找了找，找到了没过时的配置

三者搭配

# 配置支持共享的 Data Id
spring.cloud.nacos.config.shared-configs[0].data-id=nacos-service.properties
 
# 配置 Data Id 所在分组，缺省默认 DEFAULT_GROUP
spring.cloud.nacos.config.shared-configs[0].group=DEFAULT_GROUP
 
# 配置Data Id 在配置变更时，是否动态刷新，缺省默认 false
spring.cloud.nacos.config.shared-configs[0].refresh=true

　　

 环境隔离

如果之前使用的是eureka,

使用

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
替换
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>就可以了
注解使用@EnableDiscoveryClient

 

 消费者springboot使用2.4.2版本时，pom依赖加入

?

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-loadbalancer</artifactId>
        </dependency>

　　消费者springboot使用2.6.13版本，和上面引入一样的依赖

不引入报错如下

 好了关于nacos注册中心和配置中心使用就暂时到这里了
