Consul是一套开源的分布式服务发现和配置管理系统,由HashiCorp 公司用Go语言开发.
提供了微服务系统中的服务治理、配置中心、控制总线等功能。这些功能中的每一个都可以根据需要单独使用,也可以一起使用以构建全方位的服务网格,总之Consul提供了一种完整的服务网格解决方案。
它具有很多优点。包括:基于raft协议,比较简洁;支持健康检查,同时支持HTTP和DNS协议支持跨数据中心的WAN集群提供图形界面跨平台,支持Linux、Mac、Windows。
windows版解压缩后,得consul.exe,打开cmd
consul -v:
在当前Consul解压目录打开cmd窗口
执行命令
consul agent -dev:
就在刚才打开的cmd界面输入即可
浏览器输入 - http://localhost:8500/ - 打开Consul控制页。

###consul服务端口号
server:
port: 8006
spring:
application:
name: consul-provider-payment
####consul注册中心地址
cloud:
consul:
host: localhost
port: 8500
discovery:
#hostname: 127.0.0.1
service-name: ${spring.application.name}
4.主启动类
@SpringBootApplication
@EnableDiscoveryClient
public class PaymentMain8006
{
public static void main(String[] args) {
SpringApplication.run(PaymentMain8006.class, args);
}
}
5.业务类Controller
@RestController
@Slf4j
public class PaymentController
{
@Value("${server.port}")
private String serverPort;
@RequestMapping(value = "/payment/consul")
public String paymentConsul()
{
return "springcloud with consul: "+serverPort+"\t "+ UUID.randomUUID().toString();
}
}
6.验证测试
启动项目,访问对应controller写的请求,加上端口号
http://localhost:8006/payment/consul
http://localhost:8500 - 会显示provider8006
1.新建Module消费服务order80 - cloud-consumerconsul-order80

###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: localhost
port: 8500
discovery:
#hostname: 127.0.0.1
service-name: ${spring.application.name}
4.主启动类
@SpringBootApplication
@EnableDiscoveryClient //该注解用于向使用consul或者zookeeper作为注册中心时注册服务
public class OrderConsulMain80
{
public static void main(String[] args) {
SpringApplication.run(OrderConsulMain80.class, args);
}
}
5.配置Bean
@Configuration
public class ApplicationContextConfig
{
@Bean
@LoadBalanced
public RestTemplate getRestTemplate()
{
return new RestTemplate();
}
}
6.Controller
@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;
}
}
7.验证测试
运行consul,cloud-providerconsul-payment8006,cloud-consumerconsul-order80
http://localhost:8500/ 主页会显示出consul,cloud-providerconsul-payment8006,cloud-consumerconsul-order80三服务。
8.访问测试地址 - http://localhost/consumer/payment/consul
