通过github作为分布式配置中心,在github上新建仓库:spring-cloud-learn,并创建文件夹config-repo(也可以不创建文件夹,配置会有一点不同)并上传3分文件,内容分别为:
from=local-dev
from=local-test
from=local-prod
<!-- config-server 服务配置中心 -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-server</artifactId>
</dependency>
spring:
application:
name: config-server
cloud:
config:
server:
git:
uri: https://github.com/xianghaizing/spring-cloud-learn
search-paths: config-repo
server:
port: 8888
uri 指定github地址search-paths 指定配置搜索目录@EnableConfigServer
@SpringBootApplication
public class ConfigServerApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigServerApplication.class, args);
}
}
@EnableConfigServer 启动配置中心
bootstrap.yml 高于 application.yml, bootstrap.yml一般用于加载远程配置
/{application}/{profile}[/{label}]
/{application}-{profile}.yml
/{label}/{application}-{profile}.yml
/{application}-{profile}.properties
/{label}/{application}-{profile}.properties
一定要记住这个命名规则,不然客户端获取不到配置.这个坑困扰了我好几天,终于踩平了
application 作为client的 spring.application.name (必须一致)profile 作为client的 spring.cloud.config.profilelabel 作为client的 spring.cloud.config.label (默认master)<!-- spring mvc -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>

<!-- 配置中心client端 -->

spring:
application:
name: lyf
cloud:
config:
uri: http://localhost:8888
profile: dev
label: master
server:
port: 8030
management:
endpoints:
web:
exposure:
include: refresh # 暴露刷新节点 2.x版本需要手动开启
@RefreshScope
@RestController
public class ConfigClientController {
@Value("${from}")
private String from;
@RequestMapping("/from")
public String getFrom(){
return this.from;
}
}
${from}就是远程properties文件中的from=dev中的那个key
启动服务端和客户端
由于配置文件名为lyf-dev.properties,所以访问地址为 /lyf/dev
GET http://localhost:8888/lyf/dev
{
"name": "lyf",
"profiles": [
"dev"
],
"label": null,
"version": "9dd38a778c9b4ec9d7b8e972aeabe749e24e0161",
"state": null,
"propertySources": [
{
"name": "https://github.com/xianghaizing/spring-cloud-learn/config-repo/lyf-dev.properties",
"source": {
"from": "local-dev"
}
},
{
"name": "https://github.com/xianghaizing/spring-cloud-learn/config-repo/lyf.properties",
"source": {
"from": "local"
}
}
]
}
GET http://localhost:8030/from
local-dev
修改dev配置: from=local-dev-02 并push到github
GET http://localhost:8888/lyf/dev
{
"name": "lyf",
"profiles": [
"dev"
],
"label": null,
"version": "a89342009a315c78671b31a35392158673828bba",
"state": null,
"propertySources": [
{
"name": "https://github.com/xianghaizing/spring-cloud-learn/config-repo/lyf-dev.properties",
"source": {
"from": "local-dev-02"
}
},
{
"name": "https://github.com/xianghaizing/spring-cloud-learn/config-repo/lyf.properties",
"source": {
"from": "local"
}
}
]
}
GET http://localhost:8030/from
local-dev
此时客户端并没有拿到最新配置,需要手动发送post请求执行刷新
POST http://localhost:8030/actuator/refresh
[
"config.client.version",
"from"
]
再次访问
GET http://localhost:8030/from
local-dev-02
