第十节--consul服务注册与发现

上一节将zookeeper结合springcloud服务注册与发现，但是使用的公司比较少

 

一般都使用consul

 

中文官方文档  https://www.springcloud.cc/spring-cloud-consul.html

 

官网下载consul,安装并运行Consul: 下载好之后，直接解压运行consul.exe即可，使用cmd进入consul加压目录查看版本：consul --version

 

 

启动consul, 进入consul.exe目录，cmd运行命令：consul agent -dev

 

 

启动成功之后：访问 http://localhost:8500 即可

服务提供者注册consul

  第一步：新建工程，cloud-provider-consul-payment8006 ，pom.xml文件新增依赖

<dependencies>
    <!--整合consul服务注册-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-consul-discovery</artifactId>
    </dependency>
    <!-- actuator监控信息完善 这两个包必须有-->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <dependency>
        <groupId>com.hx.springcloud</groupId>
        <artifactId>cloud-api-commos</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>druid</artifactId>
    </dependency>
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
    </dependency>


    <!--热部署  -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
        <scope>runtime</scope>
        <optional>true</optional>
    </dependency>
</dependencies>

第二步：yml文件

server:
  port: 8006
spring:
  application:
    name: cloud-payment-service #在consul注册中心的名称
  cloud:
    consul:
      host: localhost
      port: 8500  #不能写错 否则启动错误
      discovery:
        service-name: ${spring.application.name}

第三步：主启动类

@EnableDiscoveryClient //向使用consol或zookeeper作为注册中心时注册服务
@SpringBootApplication
public class PayMentApplication8006 {
public static void main(String[] args) {
SpringApplication.run(PayMentApplication8006.class,args);
}
}

其它的controller,service等和其它工程一致

服务消费者注册consul

  第一步：新建工程cloud-consumer-consulorder80,pom.xml文件

<dependencies>
    <!--整合consul服务注册-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-consul-discovery</artifactId>
    </dependency>
    <!-- actuator监控信息完善 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <dependency>
        <groupId>com.hx.springcloud</groupId>
        <artifactId>cloud-api-commos</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!--热部署  -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
        <scope>runtime</scope>
        <optional>true</optional>
    </dependency>
</dependencies>

第二步：yml文件

server:
  port: 80
spring:
  application:
    name: cloud-consumer-service #在consul注册中心的名称
  cloud:
    consul:
      host: localhost
      port: 8500
      discovery:
        service-name: ${spring.application.name}

第三步：主启动类

@EnableDiscoveryClient
@SpringBootApplication
public class ConsulOrder80 {
    public static void main(String[] args) {
        SpringApplication.run(ConsulOrder80.class,args);
    }
}

config和controller和zookeeper调用时一致

启动项目后，查看consul:  http://localhost:8500/ui/dc1/services

成功！
