consul–基础–7.2–集成springBoot–yml常用配置

1、配置说明

spring:
  application:
    name: ${project.name}
  profiles:
    active: dev
  cloud:
    consul:
      # 单机配置
      # host: 10.220.147.130
      # port: 8500
      # 集群配置
      host: 0.220.147.130:8500,10.220.147.131:8500
      config:
        # 开启配置中心
        enabled: true
        # watch选项为配置监视功能，主要监视配置的改变
        watch:
          #启用配置自动刷新
          enabled: true
          #刷新频率，单位：毫秒
          delay: 10000
          #刷新延迟时间，单位：秒
          wait-time: 30
          # 表示如果没有发现配置，是否抛出异常，true为是，false为否，当为false时，consul会打印warn级别的日志信息
        fail-fast: false

        # consul创建key值与环境的分隔符
        profile-separator: s

        # 配置文件的文件格式
        format: yaml
        # 配置文件的存储的根路径，默认为config
        prefix: config
        # 配置文件存储key的值，或者理解为文件的名称，默认为data
        data-key: data

      # 服务发现配置
      discovery:
        # 启用服务发现
        enabled: true
        # 启用服务注册
        register: true
        # 服务停止时取消注册
        deregister: true
        # 显示ip地址
        prefer-ip-address: true
        # 注册到consule的ip地址
        ip-address: 118.118.118.118

        # 健康检查频率，也就是心跳频率
        health-check-interval: 5s
        # 严重服务(监控检查不通过的服务)的检查间隔频率
        health-check-critical-timeout: 1s
        # 健康检查的路径
        health-check-path: /actuator/health


        # 服务注册标识(服务 ID)，格式为：应用名称+服务器IP+端口，请勿使用随机数，因为它会在服务重启过程中，会在consul上生成多个实例
        instance-id: ${spring.application.name}:${spring.cloud.client.ip-address}:${server.port}
        # 注册的节点名称
        service-name: consul-01
        # 使用心跳检查push机制定期向consul server汇报自身存活情况，逾期没有汇报则server认为异常。
        heartbeat:
          enabled: true
        #元数据和Consul标签
        tags: version=1.0,author=bayuqi

2、案例

先让用户服务注册到consul
注册成功后，再停止用户服务

2.1、配置

server:
  port: 9006
  servlet:
    context-path: /
spring:
  application:
    name: user-server
#  config:
#    import: "optional:consul:"
  cloud:
    consul:
      host: 192.168.187.89
      port: 8500
      discovery:
        prefer-ip-address: true
        instance-id: ${spring.application.name}:${spring.application.instance_id:${spring.cloud.client.ip-address}-${server.port}}
        # 健康检查的路径
        health-check-path: '/service'
        # 健康检查频率，也就是心跳频率
        health-check-interval: 1s
        # 严重服务(监控检查不通过的服务)的检查间隔频率
        health-check-critical-timeout: 3s
        # 健康检查超时时间
        health-check-timeout: 2s

2.2、健康检查

@RequestMapping("/service")
public String service() throws UnknownHostException {


    InetAddress localHost = InetAddress.getLocalHost();

    String hostIP = localHost.getHostAddress();
    long currentTime = System.currentTimeMillis();

    long intervalTime = (currentTime - previousTime);//请求间隔时间
    previousTime = currentTime;
    String result = "用户服务：" + hostIP + ":" + serverPort + ",请求间隔时间：" + intervalTime;
    System.out.println(result);
    return result;
}

结果：
用户服务：2.0.0.1:9006,请求间隔时间：1006
用户服务：2.0.0.1:9006,请求间隔时间：1004
用户服务：2.0.0.1:9006,请求间隔时间：1007
用户服务：2.0.0.1:9006,请求间隔时间：1005
用户服务：2.0.0.1:9006,请求间隔时间：1004
用户服务：2.0.0.1:9006,请求间隔时间：1007
用户服务：2.0.0.1:9006,请求间隔时间：1022
用户服务：2.0.0.1:9006,请求间隔时间：1006
用户服务：2.0.0.1:9006,请求间隔时间：1006
用户服务：2.0.0.1:9006,请求间隔时间：1007
用户服务：2.0.0.1:9006,请求间隔时间：1004
用户服务：2.0.0.1:9006,请求间隔时间：1004
用户服务：2.0.0.1:9006,请求间隔时间：1003
