11.springcloud的springconfig配置

分为2个步骤

示例代码：

github地址

一、配置类服务器的搭建

1.登录github.com，创建一个自己的账号和仓库，并获取仓库地址: debugggcloud_config_demo

2.从本地上传一个yml文件上去，内容如下

spring:
  profiles:
    active:
    - dev
---
spring:
  profiles: dev     #开发环境
  application: 
    name: debugggcloud-config-debuggg-dev
---
spring:
  profiles: test   #测试环境
  application: 
    name: debugggcloud-config-debuggg-test
#  请保存为UTF-8格式

3.创建一个配置类module: debugggcloud_config_3344

4.pom的复制

这里最重要的包是

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-server</artifactId>
        </dependency>

全部内容如下

<?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"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>debugggcloud_config_3344</artifactId>

        </dependency>
        <dependency>

        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jetty</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
        <!-- 热部署插件 -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>springloaded</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
        </dependency>
    </dependencies>
</project>

5.yml内容如下：

server:
  port: 3344

spring:
  application:
    name:  debugggcloud-config
  cloud:
    config:
      server:
        git:
          uri: https://github.com/mx342/debugggcloud_demo_config.git
          username: username #账号
          password: password #密码

6.启动类创建，并添加注解：@EnableConfigServer

package com.debuggg.cloud;

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

@SpringBootApplication
@EnableConfigServer
public class ConfigServer3344 {
    public static void main(String[] args) {
        SpringApplication.run(ConfigServer3344.class,args);
    }
}

7.启动，并测试：

效果如下图：

二、远程配置应用到具体的服务的搭建

1.将如下配置文件上传到上面创建的git仓库里面去

spring: 
  profiles: 
    active: 
    - dev
---
server: 
  port: 7001 #注册中心占用7001端口,冒号后面必须要有空格

spring: 
  profiles: dev
  application:
    name: debugggcloud-config-eureka-client

eureka: 
  instance: 
    hostname: eureka7001.com #冒号后面必须要有空格
  client: 
    register-with-eureka: false #当前的eureka-server自己不注册进服务列表中
    fetch-registry: false #不通过eureka获取注册信息
    service-url: 
      defaultZone: http://eureka7001.com:7001/eureka/
---
server: 
  port: 7001 #注册中心占用7001端口,冒号后面必须要有空格

spring: 
  profiles: test
  application:
    name: debugggcloud-config-eureka-client

eureka: 
  instance: 
    hostname: eureka7001.com #冒号后面必须要有空格
  client: 
    register-with-eureka: false #当前的eureka-server自己不注册进服务列表中
    fetch-registry: false #不通过eureka获取注册信息
    service-url: 
      defaultZone: http://eureka7001.com:7001/eureka/

2.将之前的eureka项目中添加一个pom坐标：

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
        </dependency>

3.创建一个bootstrap.yml(bootstrap的优先级比application还要高)

具体内容如下：

 spring:
  cloud:
    config:
      name: debugggcloud_config_client #需要从github上读取的资源名称，注意没有yml后缀名
      profile: test   #本次访问的配置项
      label: master
      uri: http://config-3344.com:3344  #本微服务启动后先去找3344号服务，通过SpringCloudConfig获取GitHub的服务地址

4.启动测试
