Explanation of SpringCloud Config Configuration Center

1. Create an Config Configuration Center project

1. Add dependencies

 <dependency>
   <groupId>org.springframework.cloud</groupId>
   <artifactId>spring-cloud-config-server</artifactId>
 </dependency>

2. To start the class, you need to add @ EnableConfigServer

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.config.server.EnableConfigServer;

/**
 * @author fusw
 */
@SpringBootApplication
@EnableConfigServer
public class ConfigCenterApplication {

  public static void main(String[] args) {
    SpringApplication.run(ConfigCenterApplication.class, args);
  }

}

3. Configuration files

eureka.instance.appname=base-iov-config
security.user.name=test
security.user.password=test
# GitLab  You must have the configuration mode of  .git  Suffix 
#  Configure default  git  The address of the warehouse 
spring.cloud.config.server.git.uri=http://xxxx/config-repo.git
# git  Relative address under warehouse address, you can configure multiple, using " , "Segmentation 
spring.cloud.config.server.git.search-paths=*
# Configuration center clone The address after the warehouse configuration file is stored 
spring.cloud.config.server.git.basedir=/data/deploy/config-repo
spring.cloud.config.server.git.force-pull=true
# git  Warehouse account number 
spring.cloud.config.server.git.username=test
# git  Warehouse password 
spring.cloud.config.server.git.password=test



#  Configure   Others git  The address of the warehouse  spring.cloud.config.server.git.repos.x.uri, iot For example 
spring.cloud.config.server.git.repos.iot.uri=http://xxxx/iot/config-repo.git
spring.cloud.config.server.git.repos.iot.search-paths=*
spring.cloud.config.server.git.repos.iot.basedir=/data/deploy/config-repo
spring.cloud.config.server.git.repos.iot.force-pull=true
# git  Warehouse account number 
spring.cloud.config.server.git.repos.iot.username=test
# git  Warehouse password 
spring.cloud.config.server.git.repos.iot.password=test
# Prefix 1 Must be configured to distinguish from the default warehouse 
spring.cloud.config.server.git.repos.iot.pattern=Iot*

# Registry center 
eureka.client.serviceUrl.defaultZone=http://xxx/eureka/

2. git repository for configuration

Create an git warehouse to store the configuration of each project. You can create folders according to the project in the project level 1 directory (the names of each project folder can be started at will, and the Config configuration center only finds the configuration according to the configuration file name), and then each project folder stores the configuration files of different environments.

For example:

Iot-TestProject-dev.yml
Iot-TestProject-prd.yml
Iot-TestProject-test.yml

It is best not to place a default configuration similar to test. yml, and if spring. profiles. active is not used in the individual project configuration files, the default configuration file will be loaded.

3. Each SpringCloud Project Configuration Access Configuration Center

In the bootstrap. properties configuration file under resource, the relevant configuration of the configuration center is as follows

#  Use the configuration file of the default warehouse 
spring.cloud.config.name=TestProject
#  Use iot Configuration file of factory library 
#spring.cloud.config.name=Iot-TestProject
# Which environment configuration file to use, in conjunction with the above configuration, determines which to use 1 Configuration files :TestProject -test.yml
spring.cloud.config.profile=test


#  Correspondence   Object for storing the profile repository git Branching 
spring.cloud.config.label=master

spring.cloud.config.username=test
spring.cloud.config.password=test

#  Open  Config  Service discovery support 
spring.cloud.config.discovery.enabled=true
#  Specify  Server  End-to-end  name That is,  Server  End  spring.application.name  Value of 
spring.cloud.config.discovery.serviceId=base-iov-config
