nacos在项目中的配置

添加依赖

        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
            <version>${nacos.version}</version>
        </dependency>

        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
            <version>${nacos.version}</version>
        </dependency>

我这里使用的版本号是2.2.8

<nacos.version>2.2.8.RELEASE</nacos.version>

在bootstrap.yml或bootstrap.properties中添加nacos配置信息

#Nacos注册中心配置
spring.cloud.nacos.config.server-addr=127.0.0.1:8848
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848

spring.application.name=provide
server.port=8080

在启动类上添加 @EnableDiscoveryClient 注解以启动服务注册和发现功能

@SpringBootApplication
@EnableDiscoveryClient
public class NacosSpringcloudDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(NacosSpringcloudDemoApplication.class, args);
    }

}

如果想要nacos服务端的配置文件实现动态刷新功能，可以在controller层加上@RefreshScope注解

@RestController
@RefreshScope
public class UserController {
    

}

我这里使用的springboot版本号是2.3.12.RELEASE，springboot和springcloud的版本号需要对应

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.12.RELEASE</version>
        <relativePath/>
    </parent>
