ConfigServerApplication 文件

package com.thefirstwind.springCloudConfigServer;

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

@EnableConfigServer
@SpringBootApplication
public class ConfigServerApplication {

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

启动验证

{
    "name": "catalogservice",
    "profiles": [
        "default"
    ],
    "label": null,
    "version": "8a06f25aeb3f28a8f06b5634eae01858b2c6465d",
    "state": null,
    "propertySources": [
        {
            "name": "https://github.com/thefirstwind/springcloud-series-config-repo.git/catalogservice.properties",
            "source": {
                "spring.datasource.username": "root",
                "spring.datasource.driver-class-name": "com.mysql.jdbc.Driver",
                "spring.datasource.password": "admin",
                "spring.datasource.url": "jdbc:mysql://localhost:3306/catalog"
            }
        }
    ]
}
http://localhost:8888/catalogservice/prod then you will get the following response with catalogservice prod configuration details.

{
    "name": "catalogservice",
    "profiles": [
        "prod"
    ],
    "label": null,
