04-Nacos-服务注册基于spring boot实现

xcg3401232024-01-31 21:54

在不依赖spring cloud 组件基础上，单独的微服务项目，实现nacos接入

1、依赖文件pom.xml

复制代码

<dependency>
    <groupId>com.alibaba.boot</groupId>
    <artifactId>nacos-discovery-spring-boot-starter</artifactId>
    <version>0.2.11</version>
</dependency>

<dependency>
    <groupId>com.alibaba.boot</groupId>
    <artifactId>nacos-config-spring-boot-starter</artifactId>
    <version>0.2.11</version>
</dependency>

2、配置参数bootstrap.yml

复制代码

# 项目自身配置
server: 
  port: 8081
  ip: 192.168.20.150
  name: MOOD-SERVICE

# nacos注册配置
nacos:
  discovery:
    server-addr: 169.254.100.102:8848
  config:
    auto-refresh: true
    server-addr: 169.254.100.102:8848

3、NacosConfig

使用NamingService添加nacos配置信息

复制代码

/***
 *
 * @author xuancg
 * @date 2023/2/7
 */
import com.alibaba.nacos.api.annotation.NacosInjected;
import com.alibaba.nacos.api.exception.NacosException;
import com.alibaba.nacos.api.naming.NamingService;
import com.alibaba.nacos.spring.context.annotation.config.NacosPropertySource;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;

import javax.annotation.PostConstruct;

@Configuration
@NacosPropertySource(dataId = "nacos-springboot-service", autoRefreshed = true)
public class NacosConfig {

    @Value("${server.port}")
    private int serverPort;

    @Value("${server.ip}")
    private String ip;

    @Value("${server.name}")
    private String applicationName;

    @NacosInjected
    private NamingService namingService;

    /**
     * 开机自动注册服务
     *
     * @throws NacosException
     */
    @PostConstruct
    public void registerInstance() throws NacosException {
        namingService.registerInstance(applicationName, ip, serverPort);
    }
}
