概述

创建一个工程名为 hello-spring-cloud-config 的项目,pom.xml 配置文件如下:

<?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>

    <parent>
        <groupId>com.snake</groupId>
        <artifactId>hello-spring-cloud-dependencies</artifactId>
        <version>1.0.0-SNAPSHOT</version>
        <relativePath>../hello-spring-cloud-dependencies/pom.xml</relativePath>
    </parent>

    <artifactId>hello-spring-cloud-config</artifactId>
    <packaging>jar</packaging>

    <name>hello-spring-cloud-config</name>
    <url>http://www.snake.com</url>
    <inceptionYear>2018-Now</inceptionYear>

    <dependencies>
        <!-- Spring Boot Begin -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <!-- Spring Boot End -->

        <!-- Spring Cloud Begin -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-server</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
        <!-- Spring Cloud End -->
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>com.snake.hello.spring.cloud.config.ConfigApplication</mainClass>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

主要增加了 spring-cloud-config-server 依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-config-server</artifactId>
</dependency>

#Application

通过 @EnableConfigServer 注解,开启配置服务器功能

package com.funtl.hello.spring.cloud.config;

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

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

#application.yml

增加 Config 相关配置,并设置端口号为:8888

spring:
  application:
    name: hello-spring-cloud-config
  cloud:
    config:
      label: master
      server:
        git:
          uri: https://github.com/topsale/spring-cloud-config
          search-paths: respo
          username:
          password:

server:
  port: 8888

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

相关配置说明,如下:

  • spring.cloud.config.label:配置仓库的分支
  • spring.cloud.config.server.git.uri:配置 Git 仓库地址(GitHub、GitLab、码云 ...)
  • spring.cloud.config.server.git.search-paths:配置仓库路径(存放配置文件的目录)
  • spring.cloud.config.server.git.username:访问 Git 仓库的账号
  • spring.cloud.config.server.git.password:访问 Git 仓库的密码

注意事项:

  • 如果使用 GitLab 作为仓库的话,git.uri 需要在结尾加上 .git,GitHub 则不用

#测试

浏览器端访问:http://localhost:8888/config-client/dev/master 显示如下:

<Environment> 
  <name>config-client</name>  
  <profiles> 
    <profiles>dev</profiles> 
  </profiles>  
  <label>master</label>  
  <version>9646007f931753d7e96a6dcc9ae34838897a91df</version>  
  <state/>  
  <propertySources> 
    <propertySources> 
      <name>https://github.com/topsale/spring-cloud-config/respo/config-client-dev.yml</name>  
      <source> 
        <foo>foo version 1</foo>  
        <demo.message>Hello Spring Config</demo.message> 
      </source> 
    </propertySources> 
  </propertySources> 
</Environment>

证明配置服务中心可以从远程程序获取配置信息

#附:HTTP 请求地址和资源文件映射

  • http://ip:port/{application}/{profile}[/{label}]
  • http://ip:port/{application}-{profile}.yml
  • http://ip:port/{label}/{application}-{profile}.yml
  • http://ip:port/{application}-{profile}.properties
  • http://ip:port/{label}/{application}-{profile}.properties
