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 }

二 提供消费配置

• pom.xml

  <dependency>
              <groupId>org.springframework.cloud</groupId>
              <artifactId>spring-cloud-starter-openfeign</artifactId>
          </dependency>
          <!--web-->
          <dependency>

  ?
          <!--nacos 一定要注意版本问题-->
          <dependency>

          </dependency>
          <dependency>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-test</artifactId>
              <scope>test</scope>
              <exclusions>
                  <exclusion>
                      <groupId>org.junit.vintage</groupId>
                      <artifactId>junit-vintage-engine</artifactId>
                  </exclusion>
              </exclusions>
          </dependency>
      </dependencies>

• application.yml

  server:
    port: 8882
  spring:
    application:
      name: nacos-consumer
    cloud:
      nacos:
        discovery:
          server-addr: 192.168.180.113:8848

• 启动类配置

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

• web层

  /**
   * @author WGR
   * @create 2019/10/25 -- 0:46
   */
  @RestController
  @RequestMapping("/test")
  public class TestController {
  ?
      @Autowired(required = false)
      private TestService testService;
  ?
      @GetMapping("/user")
      public String getUser() {
          return testService.getUser();
      }
  }

• service层

  /**
   * @author WGR
   * @create 2019/10/25 -- 0:47
   */
  @FeignClient("nacos-product")
  public interface TestService {
  ?
      @GetMapping("user")
      String getUser();
  ?
  }

  ?
