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.The concept mappings on the client and server are the same as the abstractions of Spring Environment and ProertySource, 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 it needs to run when migrating.The default implementation of the server storage backend uses git, so it easily supports the label version's configuration environment and accesses various tools for managing content.It is easy to add alternative implementations and insert them using the Spring configuration.

1. Introduce a pom-related jar package where pom.xml is configured as follows:

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

Java Code Collection Code

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);  
    }  
}
