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
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
