### **Spring Cloud Consul作为注册中心** ###

**consul官方文档：[https://www.consul.io/docs/acl/index.html][https_www.consul.io_docs_acl_index.html]**

**spring cloud官方资料：****[https://spring.io/projects/spring-cloud-consul][https_spring.io_projects_spring-cloud-consul]**

**[https://cloud.spring.io/spring-cloud-consul/reference/html/][https_cloud.spring.io_spring-cloud-consul_reference_html]**

### 一、安装consul ###

**1. 下载地址：[https://www.consul.io/downloads.html][https_www.consul.io_downloads.html]**

**到此安装成功**

### **二、配置consul服务提供者** ###

**1. 创建spring-cloud-consul-provider工程，pom.xml文件内容**

      port: 8094
    spring:
      application:
        name: spring-cloud-consul-provider
      boot:
        admin:
          client:
            url: http://localhost:8092
      zipkin:

          exposure:
            include: '*'
      endpoint:
        health:
          show-details: always

**3. api接口类**

package com.zsx.api.controller;
    
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.http.HttpStatus;
    import org.springframework.http.ResponseEntity;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    @RequestMapping("api/v1/provider")
    public class ConsulProviderTestController {
    
        @Value("${server.port}")
        private String port;
    
        @GetMapping("/{message}")
        public ResponseEntity get(@PathVariable("message") String message) {
            return new ResponseEntity(String.format("The message content is : %s, Service port is : %s", message, port), HttpStatus.OK);
        }
    }

**4. 引导类**

package com.zsx;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    
    @SpringBootApplication
    @EnableDiscoveryClient
    public class ConsulProviderApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(ConsulProviderApplication.class, args);
        }
    }

**5. 启动引导类主程序**

            </plugins>

**2. application.yml文件内容**

server:
      port: 8096
    spring:
      application:
        name: spring-cloud-consul-consumer
      boot:
        admin:
          client:
            url: http://localhost:8092
      zipkin:

          exposure:
            include: '*'
      endpoint:
        health:
          show-details: always

**3. api接口类**

package com.zsx.api.controller;
    
    import com.zsx.service.ConsumerTestService;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.http.HttpStatus;
    import org.springframework.http.ResponseEntity;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    @RequestMapping("consul/consumer/")
    public class ConsumerTestController {
    
        @Autowired
        private ConsumerTestService consumerTestService;
    
        @GetMapping("/{message}")
        public ResponseEntity get(@PathVariable("message") String message) {
            return new ResponseEntity(consumerTestService.get(message), HttpStatus.OK);
        }
    }

**4. 消费者调用服务提供者接口类**

package com.zsx.service;
    
    import com.zsx.hystrix.ConsumerTestHystrix;
    import org.springframework.cloud.openfeign.FeignClient;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.PathVariable;
    
    @FeignClient(value = "spring-cloud-consul-provider", fallback = ConsumerTestHystrix.class)
    public interface ConsumerTestService {
    
        @GetMapping(value = "/api/v1/provider/{message}")
        String get(@PathVariable("message") String message);
    }

**5. 熔断器实现类**

package com.zsx.hystrix;
    
    import com.zsx.service.ConsumerTestService;
    import org.springframework.stereotype.Component;
    
    @Component
    public class ConsumerTestHystrix implements ConsumerTestService {
    
        @Override
        public String get(String message) {
            return "Failed to get message";
        }
    }

**6. 仪表盘servlet注册类**

package com.zsx.config;
    
    import com.netflix.hystrix.contrib.metrics.eventstream.HystrixMetricsStreamServlet;
    import org.springframework.boot.web.servlet.ServletRegistrationBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    @Configuration
    public class HystrixServletDefinitions {
    
        @Bean(name = "hystrixRegistrationBean")
        public ServletRegistrationBean servletRegistrationBean() {
            ServletRegistrationBean registration = new ServletRegistrationBean(
                    new HystrixMetricsStreamServlet(), "/hystrix.stream");
            registration.setName("hystrixServlet");
            registration.setLoadOnStartup(1);
            return registration;
        }
    }

**7. 引导类**

package com.zsx;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
    import org.springframework.cloud.openfeign.EnableFeignClients;
    
    @SpringBootApplication
    @EnableDiscoveryClient
    @EnableFeignClients
    @EnableHystrixDashboard
    public class ConsulConsumerApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(ConsulConsumerApplication.class, args);
        }
    }

**8. 依次运行consul注册中心，consul服务提供者（运行2个）、consul消费者主程序**
