Spring Cloud Config Git 配置项目

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);
    }
}

三、定义Config客户端

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;
	}
}
