第一步：添加依赖

		<dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba.nacos</groupId>
            <artifactId>nacos-spring-context</artifactId>
            <version>0.2.2-RC1</version>
        </dependency>

第二步：添加config

import com.alibaba.nacos.api.annotation.NacosProperties;
import com.alibaba.nacos.spring.context.annotation.discovery.EnableNacosDiscovery;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableNacosDiscovery(globalProperties = @NacosProperties(serverAddr = "{nacos的ip}:8848"))
public class NacosConfiguration {

}

第三步：注入测试，以controller为例

使用@NacosInjected注入NamingService对象

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.api.naming.pojo.Instance;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;


@RestController
@RequestMapping
@CrossOrigin
public class NameController {
    @NacosInjected
    NamingService namingService;

    @GetMapping("name")
    public List<Instance> getService() throws NacosException {
        List<Instance> allInstances = namingService.getAllInstances("admin-dev");
        allInstances.forEach(all->{
            System.err.println(all.getIp());    //ip
            System.err.println(all.getPort());  //端口
        });
        return allInstances;
    }
}

第四步：接口测试

返回数据：

控制台打印数据：

成功！
