一、配置服务器

1. pom.xml 配置

<?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.sande</groupId>
	<artifactId>config-server</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>jar</packaging>

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

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.4.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>
		<spring-cloud.version>Finchley.SR1</spring-cloud.version>
	</properties>

	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>
		
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-security</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-config-server</artifactId>
		</dependency>
		
		
		
		<!--

			<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
		</dependency>
        -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>
		<!-- 
		<dependency>
       <groupId>com.fasterxml.jackson.core</groupId>
       <artifactId>jackson-annotations</artifactId>
       <version>2.9.6</version>
    </dependency>
    
    <dependency>

       <artifactId>jackson-databind</artifactId>
       <version>2.9.6</version>
    </dependency>
		 -->
	</dependencies>

	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>${spring-cloud.version}</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>


</project>

2. src/main/resources/application.properties 

server.port=7001
spring.application.name=config-server
spring.cloud.config.server.git.uri=https://gitee.com/lixiaxin200319/config-repo
spring.cloud.config.server.git.username=lixiaxin200319
spring.cloud.config.server.git.password=密码
spring.cloud.config.server.git.search-paths={application}
spring.cloud.config.label=master
#spring.cloud.config.server.git.repos.dev.pattern=dev/*
#spring.cloud.config.server.git.repos.dev=https://gitee.com/lixiaxin200319/config-repo/dev
spring.cloud.config.server.git.basedir=E:\\JAVA\\Spring\\config-server\\src\\main\\resources\\repos

注意：如果使用 spring.cloud.config.server.git.repos.dev=https://gitee.com/lixiaxin200319/config-repo/dev 配置了多个仓库源，会导致指定本地仓库的  spring.cloud.config.server.git.basedir 失效。

3. 启动类

package com.sande.configserver;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.config.server.EnableConfigServer;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.RestController;

//@Configuration
//@EnableAutoConfiguration
//@RestController
@EnableConfigServer
@SpringBootApplication
public class ConfigServerApplication {

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

4. 代码仓库目录结构

config-repo
  |
  |-----sdcc--sdcc-dev.properties
  |
  |-----dev

二、配置中心客户端配置

1. 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.sande</groupId>
	<artifactId>config-client</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>jar</packaging>

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

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.4.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>
		<spring-cloud.version>Finchley.SR1</spring-cloud.version>
	</properties>

	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-actuator</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-config</artifactId>
		</dependency>

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

	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>${spring-cloud.version}</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>


</project>

2. src/maiin/resources/bootstrap.yml

spring: 
  application: 
    name: sdcc
  cloud:
    config:
      uri: http://localhost:7001
      profile: dev
      label: master
      username: user
      password: 123456 
      
server:
  port: 7002

注意：上面这些属性必须配置在 bootstrap.yml 或 bootstrap.properties 中，这样 config-server 中的配置信息才能被正确加载。

3. 启动类

package com.sande.configclient;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
public class ConfigClientApplication {

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

@RefreshScope
@RestController
class MessageRestController {

    @Value("${message:Hello default}")
    private String message;
    
  

    @RequestMapping("/message")
    String getMessage() {
        return this.message;
    }
    
   /* @Value("${info}")
    private String info;
    
  

    @RequestMapping("/info")
    String getInfo() {
        return this.info;
    }*/
    
    @Value("${sdccSellLimit}")
    private String sdccSellLimit;

    @RequestMapping("/sdccSellLimit")
    String getSdccSellLimit() {
        return this.sdccSellLimit;
    }
    
    @Value("${sdccSellLimitNumber}")
    private String sdccSellLimitNumber;

    @RequestMapping("/sdccSellLimitNumber")
    String getSdccSellLimitNumber() {
        return this.sdccSellLimitNumber;
    }
   /* @Value("${name}")
    private String name;

    @RequestMapping("/name")
    String getName() {
        return this.name;
    }
    
    @Value("${id}")
    private String id;

    @RequestMapping("/id")
    String getId() {
        return this.id;
    }*/
    
    /*@Value("${prod_version}")
    private String prod_version;
    
    @RequestMapping("/prod_version")
    String getProd_version() {
        return this.prod_version;
    }*/
    
   
    

}
