SpringCloud微服務雲架構構建B2B2C電子商務平臺之-(六)分散式配置中心(Spring Cloud Config)

一、簡介

在分散式系統中,由於服務數量巨多,為了方便服務配置檔案統一管理,實時更新,所以需要分散式配置中心元件。在Spring Cloud中,有分散式配置中心元件spring cloud config ,它支援配置服務放在配置服務的記憶體中(即本地),也支援放在遠端Git倉庫中。在spring cloud config 元件中,分兩個角色,一是config server,二是config client。

二、構建Config Server

建立一個spring-boot專案,取名為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>

        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.2.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </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>

        <dependency>

            <scope>test</scope>
        </dependency>
 
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
        </dependency>
    </dependencies>

                <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>

在程式的入口Application類加上@EnableConfigServer註解開啟配置伺服器的功能,程式碼如下:

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

需要在程式的配置檔案application.properties檔案配置以下:

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倉庫地址
  • spring.cloud.config.server.git.searchPaths:配置倉庫路徑
  • spring.cloud.config.label:配置倉庫的分支
  • spring.cloud.config.server.git.username:訪問git倉庫的使用者名稱
  • spring.cloud.config.server.git.password:訪問git倉庫的使用者密碼

啟動程式:訪問http://localhost:8888/foo/dev

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

架構程式碼如下:
