SpringCloud-ServerConfig center server configuration

ServerConfig

SpringCloud components, ServerConfig is to configure the service center, components for unified management of project configuration

principle

Springboot by starting a service (server-config), configure git repository address (also svn or other), through configured file address, access to the configuration file. Other micro-service access configuration does not require access to git, you can only access by ServerConfig.

Set up

Premise summary, this building use ide: Spring Tool Suite 4

Version: 4.3.0.RELEASE
Build Id: 201906200901

Installed maven 3.6.3, and configure the network address of the warehouse unobstructed maven, some foreign address of the warehouse may not speed, slow download dependence.

Mirroring the domestic warehouse but faster https://www.cnblogs.com/Narule/p/12595960.html

Start main method of this class, see the print console console log is started successfully, successfully started, you can pass

localhost: 8888 / eureka-dev.yml view configuration information, as long as there is this file to configure address

configserver Profile Rule

/ { 应用名 } / { 环境名 } [ / { 分支名 } ]
/ { 应用名 } - { 环境名 }.yml
/ { 应用名 } - { 环境名 }.properties
/ { 分支名 } / { 应用名 } - { 环境名 }.yml
/ { 分支名 } / { 应用名 } - { 环境名 }.properties

If a springboot service called eureka, eureka configuration is as follows

bootstrap.yml

spring:
  application:
    name: eureka #应用名
  cloud:
    config:
     uri: localhost:8888 #配置中心的访问地址 这不是配置文件的地址，是配置服务server-config的地址
     profile: dev #环境
     label: master #分支
management:
  endpoints:
    web:
      exposure:
        include:
        - "*"
        
eureka:
  server:
    renewal-percent-threshold: 0.45
    
log:
  path: log

Then he will read

eureka-dev.yml name, git branch for the master files (default)
