SpringCloud第五节内容精简，consul注册与发现

安装可以选择Windows安装，省事

我是在docker里安装的，有点坑 ，可以看看安装文章

还是新建模块，然后提供者，再到消费者

application.yml

###consul服务端口号
server:
  port: 8006

spring:
  application:
    name: consul-provider-payment
  ####consul注册中心地址，最后一个是表示用ip地址注册而不是hostname
  cloud:
    consul:
      host: 192.168.184.128
      port: 8500
      discovery:
        hostname: 192.168.184.128
        service-name: ${spring.application.name}
        prefer-ip-address: true

 

启动类还是那两个注解

@SpringBootApplication

@EnableDiscoveryClient

 

控制器

@RestController
@Slf4j
public class PaymentController {
    @Value("${server.port}")
    private String serverPort;

    @RequestMapping(value = "/payment/consul")
    public String paymentConsul()
    {
        return "springcloud with consul: "+serverPort+"\t"+ UUID.randomUUID().toString();
    }
}

            <scope>test</scope>
        </dependency>

    </dependencies>
</project>

 

然后是消费者

application.yml

###consul服务端口号
server:
  port: 80

spring:
  application:
    name: cloud-consumer-order
  ####consul注册中心地址
  cloud:
    consul:
      host: 192.168.184.128
      port: 8500
      discovery:
        #hostname: 127.0.0.1
        service-name: ${spring.application.name}
        prefer-ip-address: true

 

启动类如上

控制器

@RestController
@Slf4j
public class OrderConsulController {
    public static final String INVOKE_URL = "http://consul-provider-payment";

    @Resource
    private RestTemplate restTemplate;

    @GetMapping(value = "/consumer/payment/consul")
    public String paymentInfo(){
        String result = restTemplate.getForObject(INVOKE_URL+"/payment/consul",String.class);
        return result;
    }
}

 

效果
