Spring Cloud Config 為分布式系統中的外部配置提供服務器和客戶端支持。使用 Config Server，您可以在所有環境中管理應用程序的外部屬性。客戶端和服務器上的概念映射與Spring Environment和PropertySource抽象相同，

因此它們與 Spring 應用程序非常契合，但可以與任何以任何語言運行的應用程序一起使用。隨著應用程序通過從開發人員到測試和生產的部署流程，您可以管理這些環境之間的配置，並確定應用程序具有遷移時需要運行的一切。服務器存儲後端的默認實現使用 git，因此它輕松支持標簽版本的配置環境，以及可以訪問用於管理內容的各種工具。很容易添加替代實現，並使用 Spring 配置將其插入。

2. 引入 pom 相關 jar 包，其中 pom.xml 配置如下：

<?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">

    <parent>
        <groupId>com.ml.honghu</groupId>
        <artifactId>commonservice</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>

        </dependency>
        <dependency>

        <dependency>

        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>

    <execution>

    <goals><goal>build-info</goal>
    </goals>
    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</project>
 

3. 在src/main/java進行ConfigApplication.java啟動文件配置：

package com.ml.honghu; 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; 
@EnableConfigServer
@EnableEurekaClient
@SpringBootApplication public class ConfigApplication{      public static void main(String[] args) { 
        SpringApplication.run(ConfigApplication.class, args); 
    } 
 

4. 在 src/main/resource 下進行 bootstrap.yml 配置

server:  port: 8888 spring:   application: 
    name: commonservice-config-server 
  profiles: 
    active: discovery,native   cloud:     config:       server:         git: 
uri: http://192.168.0.254/honghu.../honghu-config.git           username: honghu           password: 123456           searchPaths: config-dev security:   basic: 
    enabled: true   user: 
    name: honghu     password: 123456 eureka:   client:     serviceUrl: 
defaultZone: http://honghu:123456@localhost:8761/eureka/       honghuZone: http://honghu:123456@localhost:8761/eureka/     registry-fetch-interval-seconds: 300     availability-zones: 
honghu: honghuZone   instance: 
    prefer-ip-address: true     metadataMap:       version: 1.0       variant: A       user: ${security.user.name}       password: ${security.user.password} management: 
  security: 
    enabled: false 

註意： 如果不從遠程 git 或者 svn 庫加載配置文件信息，可以配置加載本地地址，比如 window 下配置使用：

server:  port: 8888 spring:   application: 
    name: commonservice-config-server 
  profiles: 
    active: discovery,native   cloud:     config:       server: 
<span   style="color:   #ff0000;">native.searchLocations: d:/honghu-config</span>
security:   basic: 
    enabled: true   user: 
    name: honghu     password: 123456 eureka:   client:     serviceUrl: 
defaultZone: http://honghu:123456@localhost:8761/eureka/       honghuZone: http://honghu:123456@localhost:8761/eureka/     registry-fetch-interval-seconds: 300     availability-zones: 
honghu: honghuZone   instance: 
    prefer-ip-address: true     metadataMap:       version: 1.0       variant: A       user: ${security.user.name}       password: ${security.user.password} management: 
  security: 
enabled: false 

到此，整個 config 服務項目配置完畢！！
