nacos服务提供者

一、创建服务提供者

IDEA中创建聚合工程Nacos作为父工程

二、依赖管理

父POM

消费者依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>com.zw</groupId>
        <artifactId>springcloud-alibaba-example</artifactId>
        <version>1.0-SNAPSHOT</version>
        <relativePath>../pom.xml</relativePath>
    </parent>
    <artifactId>nacos-server-consumer</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>nacos-server-consumer</name>
    <description>消费者</description>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
    </dependencies>
</project>

三、配置文件

配置文件application.yml进行如下配置

server:
  # 端口
  port: 8088
spring:
  application:
  #  应用程序的名称
    name: nacos-server-provider
  cloud:
    nacos:
      discovery:
        # 注册中心地址
        server-addr: 127.0.0.1:8848

四、开启服务注册发现功能

在Application.java的入口程序类上添加注解@EnableDiscoveryClient 开启服务注册发现功能

@SpringBootApplication
@EnableDiscoveryClient
public class NacosServerProviderApplication {
    public static void main(String[] args) {
        SpringApplication.run(NacosServerProviderApplication.class, args);
    }
}

控制层

import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@Slf4j
public class NacosProviderController {
    @Value("server.port")
    String port;

    @RequestMapping("/")
    public String test() {
        return port + ": 生产者";
    }
