Spring Cloud Config Git 配置项目

SpringBoot应用使用application.properties或application.yml作为配置文件，
SpringCloud微服务框架管理诸多服务，如果每个服务都配置自己配置文件，配置工作
非常繁琐，SpringCloud提供了Config子项目，此项目核心就是配置中心，通过一个服务器和多个客户端实现配置服务。

例程：

一、在Git创建仓库

二、定义Config-Server

POM.xml

	</build>

</project>

application.properties配置

server.port=8150
spring.application.name=config-server

spring.cloud.config.server.git.uri=https://github.com/qixiangchen/springcloudconfig
spring.cloud.config.server.git.username=xxx
spring.cloud.config.server.git.password=xxx

启动类

package com.gf.eureka_order;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.config.server.EnableConfigServer;

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

通过浏览器访问配置

http://localhost:8150/order/prod

http://localhost:8150/order/test

三、定义Config客户端

POM.xml

<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/maven-v4_0_0.xsd">

  <version>0.0.1-SNAPSHOT</version>
  <name>eureka-order Maven Webapp</name>
  <url>http://maven.apache.org</url>
	<!--

	</parent>
	
	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	</properties>

		 -->
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-config</artifactId>
		</dependency>
	</dependencies>
  
	<!-- 
		Spring Cloud的命名没有按照版本方式管理，是采用命名方式，
		版本名称采用伦敦地铁站的名称命名，根据字母表的顺序对应版本时间顺序，
		比如最早的Release版本号为Angel，第二个Release版本为Brixton
	 -->
	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>Dalston.SR1</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>
	
	<!-- 
	 根据SpringCloud约定打成可以独立执行Jar包，使用Maven命令
	 mvn  package  spring-boot:repackage
	 -->
	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

</project>

配置文件bootstrap.properties

server.port=8250
spring.application.name=order

spring.cloud.config.profile=test
spring.cloud.config.uri=http://localhost:8150/

启动类

package com.gf.eureka_order;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;


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

Controller

package com.gf.eureka_order;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/configclient")
public class ConfigCtrl {
	@Value("${name}")
	String name = null;
	
	@RequestMapping("/showname")
	public String showname()
	{
		return name;
	}
}

测试效果

Config-Client项目通过Config-Server使用Git仓库中的配置
