SpringCloud之Nacos服务发现(十六)

一 服务提供配置

• pom.xml

 <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!--nacos 一定要注意版本问题-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        <version>0.9.0.RELEASE</version>
    </dependency>
</dependencies>

• application.yml

  server:
    port: 8881
  spring:
    application:
      name: nacos-product
    cloud:
      nacos:
        discovery:
          server-addr: 192.168.180.113:8848

• 启动类

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

• web层

   1 /**
   2  * @author WGR
   3  * @create 2019/10/25 -- 0:29
   4  */
   5 @RestController
   6 @RequestMapping("/user")
   7 public class UserController {
   8     @GetMapping
   9     public String getUser(){
  10         return "admin";
  11     }
  12 }
