简介
当我们的业务系统越来越庞大复杂的时候，各种配置就会层出不群。一旦配置修改了，那么我们就是必须修改后停服务，然后再上线，如果服务少，我们可以手动来操作，如果是成千上百的服务，如果是手动操作，肯定就不合适宜了，然后SpringCloudConfig就出来了，就是我们通常意义上的配置中心，把应用原本放在本地文件的配置抽取出来放在中心服务器，从而能够提供更好的管理、发布能力。Java B2B2C多用户商城 springboot架构-config-bus(十三)
SpringCloudConfig分服务端和客户端，服务端负责将git（svn或本地文件系统）中存储的配置文件发布成REST接口，客户端可以从服务端REST接口获取配置。但客户端并不能主动感知到配置的变化，从而主动去获取新的配置，这需要每个客户端通过POST方法触发各自的/refresh。
SpringCloudBus通过一个轻量级消息代理连接分布式系统的节点。这可以用于广播状态更改（如配置更改）或其他管理指令。SpringCloudBus提供了通过POST方法访问的endpoint/bus/refresh，这个接口通常由git的webhook功能调用，用以通知各个SpringCloudConfig的客户端去服务端更新配置，本节就讲怎么搭建一套自动刷新的spring cloud config
一、创建模块
模块结构如下：
二、maven聚合模块microservice-config的pom.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

三、配置中心模块（microservice-config-eureka）
3.1、pom.xml
<?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">
<parent>
<artifactId>miroservice-config</artifactId>
<groupId>com.jacky</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>microservice-config-eureka</artifactId>
<packaging>jar</packaging>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka-server</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<executions>
<!--设置在执行maven 的install时构建镜像-->
<execution>
<id>build-image</id>
<phase>install</phase>
<goals>
<goal>build</goal>
</goals>
</execution>
</executions>
<configuration>
<!--安装了docker的主机，并且打开了api remote接口设置-->
<dockerHost>http://192.168.6.130:5678</dockerHost>
<pushImage>true</pushImage><!--设置上传镜像到私有仓库，需要docker设置指定私有仓库地址-->
<!--镜像名称-->
<imageName>${docker.repostory}/${docker.image.prefix}/${project.artifactId}:${project.version}</imageName>
<!--镜像的基础版本-->
<baseImage>java:openjdk-8-jdk-alpine</baseImage>
<!--镜像启动参数-->
<entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint>
<resources>
<resource>
<targetPath>/</targetPath>
<directory>${project.build.directory}</directory>
<include>${project.build.finalName}.jar</include>
</resource>
</resources>
</configuration>
</plugin>
</plugins>
</build>
</project>
3.2、application.yml
spring:
application:
name: microservice-config-server
security:
basic:
enabled: true
user:
name: jacky
password: admin
server:
port: 9511
eureka:
client:
register-with-eureka: false
fetch-registry: false
service-url:
defaultZone: http://jacky:admin@localhost:9511/eureka
3.3、启动类EurekaApplication.java
package com.jacky.cloud;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaApplication.class, args);
}
}
3.3、启动类EurekaApplication.java
package com.jacky.cloud;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaApplication.class, args);
}
}
四、配置中心服务端（microservice-config-server）
4.1、pom.xml文件
