1. introduce

Spring Cloud Config provides server and client support for external configuration in distributed systems. With Config Server, you can manage the external properties of your application in all environments. Conceptual mapping on client and server is the same abstraction as Spring Environment and Property Source, so they fit well with Spring applications, but can be used with any application running in any language. As applications go through the deployment process from developers to testing and production, you can manage the configuration between these environments and determine that the application has everything to run when it is migrated. The default implementation of the server storage backend uses git, so it easily supports the tag version configuration environment and accesses various tools for managing content. It's easy to add alternative implementations and insert them using Spring configuration.

1. Introduce pom-related jar packages, where pom.xml is configured as follows:

<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        </plugins>

</project>  

1. ConfigApplication.java startup file configuration in src/main/java:

package com.ml.honghu;  
  
import org.springframework.boot.SpringApplication;  
import org.springframework.boot.autoconfigure.SpringBootApplication;  
import org.springframework.cloud.config.server.EnableConfigServer;  
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;  
  
@EnableConfigServer  
@EnableEurekaClient  
@SpringBootApplication  
public class ConfigApplication {  
  
    public static void main(String[] args) {  
        SpringApplication.run(ConfigApplication.class, args);  
    }  
}  

1. bootstrap.yml configuration under src/main/resource

server:   
port: 8888  
spring:  
  application:  
    name: commonservice-config-server  
  profiles:  
    active: discovery,native  
  cloud:  
    config:  
      server:  
        git:  
          uri: http://192.168.0.254/honghu.../honghu-config.git  
          username: honghu  
          password: 123456  
          searchPaths: config-dev  
security:  
  basic:  
    enabled: true  
  user:  
    name: honghu  
    password: 123456  
eureka:  
  client:  
    serviceUrl:  
      defaultZone: http://honghu:123456@localhost:8761/eureka/  
      honghuZone: http://honghu:123456@localhost:8761/eureka/  
    registry-fetch-interval-seconds: 300  
    availability-zones:  
      honghu: honghuZone  
  instance:  
    prefer-ip-address: true  
    metadataMap:  
      version: 1.0  
      variant: A  
      user: ${security.user.name}  
      password: ${security.user.password}  
management:  
  security:  
    enabled: false  

Note: If you don't load configuration file information from remote git or svn libraries, you can configure the loading local address, such as configuration under window s:

server:   
port: 8888  
spring:  
  application:  
    name: commonservice-config-server  
  profiles:  
    active: discovery,native  
  cloud:  
    config:  
      server:  
        <span style="color: #ff0000;">native.searchLocations: d:/honghu-config</span>  
security:  
  basic:  
    enabled: true  
  user:  
    name: honghu  
    password: 123456  
eureka:  
  client:  
    serviceUrl:  
      defaultZone: http://honghu:123456@localhost:8761/eureka/  
      honghuZone: http://honghu:123456@localhost:8761/eureka/  
    registry-fetch-interval-seconds: 300  
    availability-zones:  
      honghu: honghuZone  
  instance:  
    prefer-ip-address: true  
    metadataMap:  
      version: 1.0  
      variant: A  
      user: ${security.user.name}  
      password: ${security.user.password}  
management:  
  security:  
    enabled: false  

So far, the whole config service project has been configured!!

From now on, I will record the construction process and essence of spring cloud micro-service Cloud Architecture recently developed, and help more friends who are interested in developing spring cloud framework. Let's discuss the construction process of spring cloud architecture and how to apply it to enterprise projects.
