方式1：

  1.将配置信息放在缓存中，缓存中没有就去数据库中取然后再更新缓存。

方式2：

  1.将配置文件信息存放在版本控制（git,svn）中。

  2.server-config服务缓存配置文件信息，可以被其他服务进行调用读取。

方式2：

1.创建service-config项目导包

2.github配置文件上传，application.properties配置文件配置

spring.application.name=server-config
server.port=9090
spring.cloud.config.server.git.uri=https://github.com/shaly/config-server.git
spring.cloud.config.server.git.searchPaths=respo
spring.cloud.config.label=master
spring.cloud.config.server.git.username=
spring.cloud.config.server.git.password=
#spring.cloud.config.server.git.uri：git仓库地址
#spring.cloud.config.server.git.searchPaths：配置仓库路径
#spring.cloud.config.label：分支
#spring.cloud.config.server.git.username：访问git仓库的用户名,公开时可以不写
#spring.cloud.config.server.git.password：访问git仓库的用户密码,公开时可以不写

3.启动项配置注解

package com.syf.study;

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

@EnableConfigServer //开启配置
@SpringBootApplication
public class ServiceConfigApplication {

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

4.访问测试

配置成功

5.创建service-config-client项目，导包

<?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.syf.study</groupId>
	<artifactId>service-config-client</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>jar</packaging>

	<name>service-config-client</name>
	<description>Demo project for Spring Boot</description>

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.5.14.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>

	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter</artifactId>
			<version>1.2.3.RELEASE</version>
		</dependency>

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>
		<!--springcloud config-->
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-config</artifactId>
		</dependency>

	</dependencies>

	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>Dalston.RC1</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>

			<name>Spring Milestones</name>
			<url>https://repo.spring.io/milestone</url>
			<snapshots>
				<enabled>false</enabled>
			</snapshots>
		</repository>
	</repositories>
</project>

6.application.properties配置文件配置

spring.application.name=service-config-client
spring.cloud.config.label=master
spring.cloud.config.profile=dev
spring.cloud.config.uri= http://localhost:9090/
server.port=9091

7.创建访问类

package com.syf.study.controller;


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

@RestController
public class GetConfigController {
    @Value("${foo}")
    private String foo;
    @Value("${username}")
    private String username;
    @Value("${alibabaurl}")
    private String alibabaurl;
    @RequestMapping("/getConfigs")
    public String getConfigs(){
        return "foo="+foo+";username="+username+";alibabaurl="+alibabaurl;
    }

}

8.启动测试
