(九)整合spring cloud雲服務架構 – commonservice-config配置服務搭建

介紹

Spring Cloud Config為分佈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，因此它輕鬆支持標籤版本的配置環境，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。

引入pom相關jar包，其中pom.xml配置如下：

<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">

            </plugin>  
        </plugins>  
    </build>  
</project>

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

org.springframework.boot.SpringApplication;
org.springframework.boot.autoconfigure.SpringBootApplication;
org.springframework.cloud.config.server.EnableConfigServer;
org.springframework.cloud.netflix.eureka.EnableEurekaClient;
@EnableConfigServer
@EnableEurekaClient
@SpringBootApplication
class ConfigApplication {

public static void main(String[] args) {
```
   SpringApplication.run(ConfigApplication.class, args);  
```
}
}

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

注意：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：

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！！

從現在開始，我這邊會將近期研發的spring cloud微服務雲架構的搭建過程和精髓記錄下來，幫助更多有興趣研發spring cloud框架的朋友，大家來一起探討spring cloud架構的搭建過程及如何運用於企業項目。（企業架構源碼可以加求球：叄五三陸二肆柒二伍玖）
