服务提供者注册

2、Nacos作为服务注册中心演示

1、官方文档 ：https://spring-cloud-alibaba-group.github.io/github-pages/hoxton/en-us/index.html#_introduction

2、基于Nacos的服务提供者

在父POM中

        <dependency>
          <groupId>com.alibaba.cloud</groupId>
          <artifactId>spring-cloud-alibaba-dependencies</artifactId>
          <version>2.1.0.RELEASE</version>
          <type>pom</type>
          <scope>import</scope>
        </dependency>

1、新建Module
2、POM
在本项目中引入

 <dependencies>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>com.tfjy.springcloud</groupId>
            <artifactId>cloud-api-commons</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

3、YML

server:
  port: 9001
spring:
  application:
    name: nacos-payment-provider
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848 #配置nacos地址
management: （监控的端点）
  endpoints:
    web:
      exposure:
        include: '*'

4、主启动

@SpringBootApplication
@EnableDiscoveryClient
public class PaymentMain9001 {
    public static void main(String[] args) {
        SpringApplication.run(PaymentMain9001.class,args);
    }
}

5、业务类

@RestController
public class PaymentController {
    @Value("${server.port}")
    private String serverPort;
    @GetMapping(value = "/payment/nacos/{id}")
    public String getPayment(@PathVariable("id") Integer id){
        return "nacos registry,serverPort:"+serverPort+"\t id"+id;
    }
}

6、测试
