我是靠谱客的博主丰富白开水，最近开发中收集的这篇文章主要介绍Spring Cloud实战(四)-配置中心一.配置中心config-server，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

接着上一篇 Spring Cloud实战(三)-监控中心现在开始搭建配置中心

3.ConfigApplication.java

package com.example.config;

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;

/**
 * @author 86188
 */
@SpringBootApplication
@EnableEurekaClient
@EnableConfigServer
public class ConfigApplication {
    public static void main(String[] args) {
        SpringApplication.run(ConfigApplication.class, args);
    }
}

4.测试

环境准备

该模块用到了RabbitMQ,此处我使用了docker快速搭建了RabbitMQ环境,如果你已经有了RabbitMQ环境可以略过.如果没有,可以查看我的其他博客Windows10家庭版上安装docker等其他相关博客.

docker run -dp 5672:5672 -p 15672:15672 --name rabbitmq -v D:/WinLinux/docker/rabbitmq/data:/var/lib/rabbitmq -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=yaoyong  rabbitmq:3.8.9-management

启动项目

依次启动之前的项目

java -jar register-server-0.0.1-SNAPSHOT.jar

java -jar monitor-server-0.0.1-SNAPSHOT.jar

java -jar config-server-0.0.1-SNAPSHOT.jar

git上添加一个配置,然后测试传送门

测试内容如下

spring:
  datasource:
    driverClassName: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306
    username: root
    password: root
#  rabbitmq:
#    virtual-host: /mqbus
#    host: localhost
#    port: 5672
#    username: mqbus
#    password: mqbus

Spring Cloud Config官方文档

HTTP 服务具有以下形式的资源:

/{application}/{profile}[/{label}]
/{application}-{profile}.yml
/{label}/{application}-{profile}.yml
/{application}-{profile}.properties
/{label}/{application}-{profile}.properties

例如:

curl localhost:8888/foo/development
curl localhost:8888/foo/development/master
curl localhost:8888/foo/development,db/master
curl localhost:8888/foo-development.yml
curl localhost:8888/foo-db.properties
curl localhost:8888/master/foo-db.properties

修改测试内容

spring:
  datasource:
    driverClassName: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306
    username: root
    password: root
  rabbitmq:
    virtual-host: /mqbus
    host: localhost
    port: 5672
    username: mqbus
    password: mqbus
