SpringCloud之Config配置中心目录`config` 简介`config` 作用`config` 架构 config 简介 springcloud config 项目是一个解决分布式系统的配置管理方案。它包含了 client 和 server 两个部分，server 端提供配置文件的存储、以接口的形式将配置文件的内容提供出去，client 端通过接口获取数据、并依据此数据初始化自己的应用目前 springcloud config 的使用主要是通过 git/svn 方式做一个配置中心，然后每个服务从其中获取自身配置所需的参数 spring 阅读详情

1.config pom文件

2.配置文件

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:10000/eureka/
spring:
  application:
    name: springcloud-config
  cloud:
    config:
      server:
        git:
          uri: https://gitee.com/wangzhejun/springcloudconfig.git
          search-paths: /springcloudconfig
          username: *******
          password: *******
server:
  port: 9005

3.启动类

package com.knife.ConfigTest;

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;

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

4.启动配置项目，访问浏览器能看到git 上的配置信息

{"name":"application","profiles":["dev"],"label":"master","version":"3893e4e9589514a16f3ae2b22469c59c37a42d08","state":null,"propertySources":[{"name":"https://gitee.com/wangzhejun/springcloudconfig.git/application-dev.yml","source":{"my.message":1234567,"word":"test"}}]}

5.客户端pom文件

<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.knife</groupId>
  <artifactId>ProviderTest</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>jar</packaging>

  <name>ProviderTest</name>
  <url>http://maven.apache.org</url>

  <parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.5.RELEASE</version>
		<relativePath /> 
	</parent>

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

	</properties>

	<dependencies>
		<dependency>

		</dependency>
		
		<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>${spring-cloud.version}</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>
</project>

6.客户端配置bootstrap.yml(优先级高于application.yml)

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:10000/eureka/
spring: 
  application: 
    name: providerTest
  cloud:
    config:
      name: application
      profile: dev
      label: master
      discovery:
        enabled: true
        serviceId: springcloud-config
server:
  port: 2222

7.启动类

package com.knife.ProviderTest;

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


@EnableDiscoveryClient
@SpringBootApplication
public class ProviderApp {

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

8.controller层

package com.knife.ProviderTest;

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

@RestController
public class ProviderController {
	
	@Value("${my.message}")
	private String message;

	@RequestMapping(value = "/test", method = RequestMethod.GET)
	public String test() {
		return "i am provider "+message;
	}

}

9.启动客户端能看到获取配置日志

2019-12-02 13:38:37.088  INFO 9720 --- [           main] c.c.c.ConfigServicePropertySourceLocator : Fetching config from server at : http://172.17.10.30:9005/
