我的命名空间是centos
效果图
可以是yml格式，名称不要变

配置文件application.properties
server.port=8081 #nacos注册 spring.application.name=nacos-service spring.cloud.nacos.discovery.server-addr=192.168.31.50:8850 spring.cloud.nacos.discovery.namespace=7dd82e29-1903-4e70-b59b-40b9a59ebd3e management.endpoints.web.exposure.include=* # 设置Nacos客户端日志级别为DEBUG logging.level.com.alibaba.nacos=DEBUG logging.level.com.ip=debug logging.level.web=debug
配置文件bootstrap.properties
server.port=8081 #nacos配置 #2024.3.1 13:56 add spring.cloud.nacos.config.server-addr=192.168.31.50:8850 spring.cloud.nacos.config.namespace=7dd82e29-1903-4e70-b59b-40b9a59ebd3e spring.cloud.nacos.config.group=DEFAULT_GROUP spring.cloud.nacos.config.file-extension=properties # 设置Nacos客户端日志级别为DEBUG logging.level.com.alibaba.nacos=DEBUG logging.level.com.ip=debug logging.level.web=debug
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
