SpringCloud uses Config to implement a distributed configuration center and achieve unified management of configurations

Before using SpringCloud's Config to implement a distributed configuration center, it is necessary to introduce corresponding dependency class libraries. The following are the Maven coordinates and a brief introduction of SpringCloud Config: <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-config-server</artifactId> </dependency> This class library provides the ability to create and start configuration center services. In order to implement a distributed configuration center, it is necessary to configure the configuration center service in the Spring Boot application. The following is a complete example that demonstrates how to use SpringCloud Config to implement a distributed configuration center: Firstly, create a Spring Boot application and configure the following properties in the 'application. properties' file: properties spring.application.name=config-server server.port=8888 spring.cloud.config.server.git.uri=<git-repo-url> Among them, 'spring. application. name' is used to define the application name, 'server. port' is used to define the application port number, and 'spring. cloud. config. server. git. uri' is used to specify the URL of the Git repository, which will be used to store configuration files. Then, create a startup class' ConfigServerApplication. java 'and add the' @ Enable ConfigServer 'annotation to enable the Configuration Center service: import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.config.server.EnableConfigServer; @SpringBootApplication @EnableConfigServer public class ConfigServerApplication { public static void main(String[] args) { SpringApplication.run(ConfigServerApplication.class, args); } } Next, create a configuration file named 'config. properties' and submit it to the Git repository. The content of the configuration file is as follows: properties greeting.message=Hello, World! Finally, run the 'ConfigServerApplication' class to start the Configuration Center service. By accessing` http://localhost:8888/config/default `You can obtain the content of the configuration file. Finally, for the implementation of this sample, a simple distributed configuration center service was implemented using SpringCloud Config. By storing the application's configuration files in the Git repository, unified configuration management can be achieved. After using the '@ enableConfigServer' annotation to enable the Configuration Center service, the configuration file can be accessed through the HTTP interface.
