Spring Cloud Config可以用来作分布式配置中心,本质上ConfigServer会从git / svn / 本地目录上下载到本地环境,EnvironmentController提供了一些了接口给ConfigClient启动时调用,EnvironmentController会返回本地缓存的配置文件给ConfigClient,从而实现分布式配置
首先我们需要创建一个server端工程,pom代码如下
<?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"

</project>
application.yml配置
server:
port: 8888
spring:
#config server 配置 ,从git获取配置
cloud:
config:
server:
git:
uri: https://gitee.com/**********
# username: ******* 如果是私有项目需要填写
# password: ******* 如果是私有项目需要填写
uri填写git地址,这里的配置是从git获取的,也可以使用本地文件填写配置
Application主类代码,主要是@EnableConfigServer
package com.hlab.gongura;
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;
import org.springframework.cloud.netflix.feign.EnableFeignClients;
@EnableEurekaClient
@EnableFeignClients
@SpringBootApplication
@EnableConfigServer
public class GonguraApplication {
public static void main(String[] args) throws Exception {
SpringApplication.run(GonguraApplication.class, args);
}
}
配置完成后试下访问看看得到的结果
{
"name": "application-dev",
"profiles": ["default"],
"label": null,
"version": null,
"state": null,
"propertySources": [{
"name": "https://gitee.com/CheungQ/spring-cloud-config-repository/application-dev.yml",
"source": {
"demo.title": "new 新内容 (yml 11文件)"
}
}]
}
远程git中的配置文件application-prod.yml中的内容为
demo:
title: "prod env title"
至此,server端配置完成,接下来我们要配置的是client端,client端其实就是一个普通的工程,在resources目录下创建一个新的配置文件bootstrap.yml,注意不是application.yml,内容如下
spring:
application:
name: orchid-client
cloud:
config:
uri: http://localhost:8888
name: application
profile: prod
接下来就可以直接用@value注解获取配置了,另外有个tips,本地配置中最好加下对应的配置,比如我在application.yml中加了
demo:
title: "本地"
否则会报错
