springboot整合nacos註冊中心和配置中心

我的名稱空間是centos

效果圖

可以是yml格式，名稱不要變

springboot版本2.1.6

pom依賴

　　配置檔案application.properties

server.port=8081

#nacos註冊
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=*

# 設定Nacos客戶端日誌級別為DEBUG
logging.level.com.alibaba.nacos=DEBUG

logging.level.com.ip=debug
logging.level.web=debug

　　配置檔案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

# 設定Nacos客戶端日誌級別為DEBUG
logging.level.com.alibaba.nacos=DEBUG



logging.level.com.ip=debug
logging.level.web=debug

　　

請記得在bootstrap.properties檔案中新增配置

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

後面又找了找，找到了沒過時的配置

三者搭配

# 配置支援共享的 Data Id
spring.cloud.nacos.config.shared-configs[0].data-id=nacos-service.properties

# 配置 Data Id 所在分組，預設預設 DEFAULT_GROUP
spring.cloud.nacos.config.shared-configs[0].group=DEFAULT_GROUP

# 配置Data Id 在配置變更時，是否動態重新整理，預設預設 false
spring.cloud.nacos.config.shared-configs[0].refresh=true

　　

環境隔離

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>
替換

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>就可以了
註解使用@EnableDiscoveryClient

消費者springboot使用2.4.2版本時，pom依賴加入

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

　　消費者springboot使用2.6.13版本，和上面引入一樣的依賴

不引入報錯如下

好了關於nacos註冊中心和配置中心使用就暫時到這裡了
