### 一、简介 ###

在分布式系统中，由于服务数量巨多，为了方便服务配置文件统一管理，实时更新，所以需要分布式配置中心组件。在Spring Cloud中，有分布式配置中心组件spring cloud config ，它支持配置服务放在配置服务的内存中（即本地），也支持放在远程Git仓库中。在spring cloud config 组件中，分两个角色，一是config server，二是config client。

### 二、构建Config Server ###

创建一个spring-boot项目，取名为config-server,其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">
        <modelVersion>4.0.0</modelVersion>
     
        <groupId>com.forezp</groupId>
        <artifactId>config-server</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <packaging>jar</packaging>
     
        <name>config-server</name>
        <description>Demo project for Spring Boot</description>
     
        <parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>1.5.2.RELEASE</version>
            <relativePath/> 
        </parent>
     
        <properties>
            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
            <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
            <java.version>1.8</java.version>
        </properties>
     
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-config-server</artifactId>
            </dependency>
     
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>

        </dependencies>
     
        <dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>org.springframework.cloud</groupId>

                    <version>Camden.SR6</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
        </dependencyManagement>
     
     
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>
     
        <repositories>
            <repository>
                <id>spring-milestones</id>
                <name>Spring Milestones</name>
                <url>https://repo.spring.io/milestone</url>
                <snapshots>
                    <enabled>false</enabled>
                </snapshots>
            </repository>
        </repositories>
     
     
    </project>

在程序的入口Application类加上@EnableConfigServer注解开启配置服务器的功能，代码如下：

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

需要在程序的配置文件application.properties文件配置以下：

spring.application.name=config-server
    server.port=8888
     
     
    spring.cloud.config.server.git.uri=https://github.com/forezp/SpringcloudConfig/
    spring.cloud.config.server.git.searchPaths=respo
    spring.cloud.config.label=master
    spring.cloud.config.server.git.username=your username
    spring.cloud.config.server.git.password=your password

*  spring.cloud.config.server.git.uri：配置git仓库地址
 *  spring.cloud.config.server.git.searchPaths：配置仓库路径
 *  spring.cloud.config.label：配置仓库的分支
 *  spring.cloud.config.server.git.username：访问git仓库的用户名
 *  spring.cloud.config.server.git.password：访问git仓库的用户密码

如果Git仓库为公开仓库，可以不填写用户名和密码，如果是私有仓库需要填写，本例子是公开仓库，放心使用。

远程仓库[https://github.com/forezp/SpringcloudConfig/][https_github.com_forezp_SpringcloudConfig] 中有个文件config-client-dev.properties文件中有一个属性：

foo = foo version 3

启动程序：访问[http://localhost:8888/foo/dev][http_localhost_8888_foo_dev]

{"name":"foo","profiles":["dev"],"label":"master",
    "version":"792ffc77c03f4b138d28e89b576900ac5e01a44b","state":null,"propertySources":[]}

架构代码如下:
