SpringBoot集成Consul服務接入配置中心

閒話少談，直奔主題

1、個人研發環境

springboot：2.1.8.RELEASE

spring.cloud：Greenwich.SR5

2、POM文件展現

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

        </plugins>
    </build>
</project>

3、bootstrap.yaml文件的編寫。(通過驗證，配置中心默認加載bootstrap.(yml|yaml|properties)配置文件，完成配置中心功能的初始化）

# consul的配置啓動環境
consul:
  host: 192.168.10.118 # 註冊地址( need )
  port: 8501 # Consul 端口( need )
  acl-token: 495af318-0822-b701-ee8d-80dc6d4d863a # 訪問token ( need )
spring:
  #consul配置
  cloud:
    # Spring Cloud Consul 通用配置項，對應 ConsulProperties 類
    consul:
      host: ${consul.host} # 註冊地址
      port: ${consul.port} # Consul 端口
      # consul配置中心
      config:
        prefix: config
        enabled: true
        format: YAML
        data-key: common
        acl-token: ${consul.acl-token}
      # Spring Cloud Consul Discovery 配置項，對應 ConsulDiscoveryProperties 類
      discovery:
        enabled: true
        # register: true # 註冊自身到consul
        deregister: true # 服務中止時取消註冊
        service-name: ${spring.application.name} # 註冊到 Consul 的服務名，默認爲 `spring.application.name` 配置項
        health-check-path: /actuator/health # 健康檢查的接口，默認爲 /actuator/health，由 Spring Boot Actuator 提供
        acl-token: ${consul.acl-token}

4、consul的系統參數配置

 5、配置完成，系統啓動成功讀取配置......
