Spring Cloud Config分布式配置服务搭建

Spring Cloud可以添加config模块为微服务做分布式配置，支持git和本地文件存储，但是最为分布式配置服务，本地存储最好仅用于测试，不然多服务器的文件系统同步是一个障碍。下面列出配置文件和代码，搭建一个分布式配置服务server。

application.yml

#APP config
REGISTRY_SERVER_URL: http://127.0.0.1:8761/eureka/
#Rabbit config
RABBITMQ_SERVER_HOST: 192.168.1.13
RABBITMQ_SERVER_PORT: 5672
RABBITMQ_SERVER_USERNAME: cloud
RABBITMQ_SERVER_PASSWORD: cloud

logging.file: logs/${spring.application.name}.log
logging.level.root: INFO
logging.level.cn.gaiasys: DEBUG
server:
  port: 8888
  tomcat:
    max-threads: 128 
    min-spare-threads: 64

spring:
  application:
    name: config-server
  main:
    banner-mode: "on"
  mvc:
    favicon.enabled: false
  rabbitmq:
    host: ${RABBITMQ_SERVER_HOST}
    port: ${RABBITMQ_SERVER_PORT}
    username: ${RABBITMQ_SERVER_USERNAME}
    password: ${RABBITMQ_SERVER_PASSWORD}
  cloud:
    config:
      server:
        git:
          uri: https://github.com/renchhao/ms-config.git
          searchPaths: ms-config
          username: 
          password: 
        native:
          search-locations: classpath:/ms-config
        overrides:
          REGISTRY_SERVER_URL: ${REGISTRY_SERVER_URL}
          spring.rabbitmq.host: ${RABBITMQ_SERVER_HOST}
          spring.rabbitmq.port: ${RABBITMQ_SERVER_PORT}
          spring.rabbitmq.username: ${RABBITMQ_SERVER_USERNAME}
          spring.rabbitmq.password: ${RABBITMQ_SERVER_PASSWORD}
#如果要启用本地配置文件提供服务,修改为native
spring.profiles.active: git

参考：http://cloud.spring.io/spring-cloud-static/Camden.SR5/#_spring_cloud_config

具体的说明在上面配置文件中已经有注释，需要注意的是native的方式，路径是file://打头，如果是windows环境需要多加一个/。如果路径是file://打头，则默认在[classpath:/, classpath:/config, file:./, file:./config]这些路径下进行搜索，如果相对目录，请带上classpath，不能直接./ms-config。

新建一个application启动类

ConfigServerApplication.java

/**
 * 分布式配置服务.
 * @author Wang.ch
 */
@EnableConfigServer
@SpringBootApplication
@EnableDiscoveryClient
public class ConfigServerApplication {
    public static void main(String[] args) {
        new SpringApplicationBuilder(ConfigServerApplication.class).web(true).run(args);
    }
}

build.gradle

dependencies {
    compile("org.springframework.cloud:spring-cloud-config-server")
    compile("org.springframework.cloud:spring-cloud-starter-eureka")
}

这个时候就可以访问：http://localhost:8888/account/prod，

config支持的url访问搜索路径：

/{application}/{profile}[/{label}]
/{application}-{profile}.yml
/{label}/{application}-{profile}.yml
/{application}-{profile}.properties
/{label}/{application}-{profile}.properties
