SpringCloud config native 配置

1.概述

最近项目使用springCloud 框架，使用config搭建git作为配置中心。

在私有化部署中，出现很多比较麻烦的和鸡肋的设计。

• 每次部署都需要安装gitlab
• 有些环境安装完gitlab，外面不能访问，不给开端口
• 实时同步比较麻烦

基于上述问题，决定将配置中心依springCloud config本地文件的方式进行改造

缺点就是每个服务器上都可以放配置文件

2、springCloud config配置方式

config配置方式有三种,本文主要介绍本地文件方式

• git方式
• svn方式
• 本地文件方式

3、部署架构

springcloud config的流程架构

4、环境搭建

springcloud config分为eureka服务，config服务器端和config客户端

1、eureka服务端搭建

1、pom.xml

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <!-- Eureka-Server 依赖 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
 <dependencyManagement>
        <dependencies>
            <!-- SpringCloud 版本控制依赖 springboot版本需要匹配cloud版本
            这里用的boot版本2.3.2.RELEASE -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Hoxton.SR12</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

2、aplication.yml

server:
  port: 8761

eureka:
  instance:
    hostname: 127.0.0.1 #eureka服务端的实例名称2
  client:
    register-with-eureka: false     #false表示不向注册中心注册自己。
    fetch-registry: false     #false表示自己端就是注册中心，我的职责就是维护服务实例，并不需要去检索服务
    service-url:
      defaultZone: http://127.0.0.1:8761/eureka/

3、启动类

package com.feng;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class SpringCloud13EurekaApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringCloud13EurekaApplication.class, args);
    }
}

4、启动测试

访问地址：http://127.0.0.1:8761/

2、config服务端搭建

1、pom.xml

    <dependencies>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!-- Eureka client -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-server</artifactId>
        </dependency>
        <!--Spring Boot Actuator，感应服务端变化-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
    </dependencies>

    <dependencyManagement>
        <dependencies>
            <!-- SpringCloud 版本控制依赖 -->
            <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>

2、application

server:
  port: 8888
spring:
  profiles:
    active: native #设置为本地config
  application:
    name: springcloud-config
  cloud:
    config:
      server:
        native:
          search-locations: d:/config-repo #本地配置的路径
#        git:
#          uri: http://222.175.101.224:8090/liuyusong/springcloud-config.git
#          search-paths: /config-repo
eureka:
  client:
    service-url.defaultZone: http://127.0.0.1:8761/eureka/
  instance:
    prefer-ip-address: true

3、启动类

package com.feng;

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
@EnableEurekaClient
@EnableConfigServer
public class SpringCloud14ConfigServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringCloud14ConfigServerApplication.class, args);
    }

}

4、测试服务器端

浏览器访问 http://localhost:8888/springcloud-config/config-base-local.yml

浏览器访问个 server端口/应用名字/文件名-环境名.yml

3、config客户端搭建并测试

1、pom.xml

  <dependencies>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!-- Eureka client -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-client</artifactId>
        </dependency>
        <!--Spring Boot Actuator，感应服务端变化-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
    </dependencies>

    <dependencyManagement>
        <dependencies>
            <!-- SpringCloud 版本控制依赖 -->
            <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>

2、application

server:
  port: 8889
spring:
  application:
    name: springcloud-15-config-client

3、bootstrap

spring:
  cloud:
    config:
      discovery:
        enabled: true
        service-id: springcloud-13-config-server #eureka的service
      name: config-test
#      name: config-test,config-test1 可以配置多个配置
eureka:
  client:
    service-url.defaultZone: http://127.0.0.1:8761/eureka/
  instance:
    prefer-ip-address: true

4、启动类

package com.feng;

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

@SpringBootApplication
@EnableDiscoveryClient
public class SpringCloud15ConfigClientApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringCloud15ConfigClientApplication.class, args);
    }
}

5、测试类

package com.feng.controller;

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

@RestController
public class TestController {

    @Value("${myconfig.name}")
    String name;
    @Value("${myconfig.version}")
    String version;
    @GetMapping("/hello")
    public  String hello()
    {
        return "ok1"+name+version;
    }

}

6、测试客户端

测试地址：http://localhost:8889/hello

5、总结

springcloud config 本地化配置的优点是不需要另外搭建gitlab或者svn，部署相对简单

缺点是 如果有多个server端需要手动同步文件，每一个服务器都需要有文件
