Spring Cloud Config Git 配置项目

r囧r小猫 2022-03-10 07:29 202阅读 0赞

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 ##

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_prod]

## 三、定义Config客户端 ##

      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

    	<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;
    	}
    }

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