1.概述
最近項目使用springCloud 框架，使用config搭建git作為配置中心。
在私有化部署中，出現很多比較麻煩的和雞肋的設計。
- 每次部署都需要安裝gitlab
- 有些環境安裝完gitlab，外面不能訪問，不給開端口
- 實時同步比較麻煩
基於上述問題，決定將配置中心依springCloud config本地文件的方式進行改造
缺點就是每個服務器上都可以放配置文件
2、springCloud config配置方式
config配置方式有三種,本文主要介紹本地文件方式
- git方式
- svn方式
- 本地文件方式
3、部署架構
springcloud config的流程架構
4、環境搭建
springcloud config分為eureka服務，config服務器端和config客戶端
1、eureka服務端搭建
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 依賴 -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>
<dependencyManagement>
<dependencies>
<!-- SpringCloud 版本控制依賴 springboot版本需要匹配cloud版本
這裡用的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服務端的實例名稱2
client:
register-with-eureka: false #false表示不向註冊中心註冊自己。
fetch-registry: false #false表示自己端就是註冊中心，我的職責就是維護服務實例，並不需要去檢索服務
service-url:
defaultZone: //127.0.0.1:8761/eureka/
3、啟動類
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、啟動測試
訪問地址：//127.0.0.1:8761/
2、config服務端搭建
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，感應服務端變化-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
</dependencies>
<dependencyManagement>
<dependencies>
<!-- SpringCloud 版本控制依賴 -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring-cloud.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
2、application
server:
port: 8888
spring:
profiles:
active: native #設置為本地config
application:
name: springcloud-config
cloud:
config:
server:
native:
search-locations: d:/config-repo #本地配置的路徑
# git:
# uri: //222.175.101.224:8090/liuyusong/springcloud-config.git
# search-paths: /config-repo
eureka:
client:
service-url.defaultZone: //127.0.0.1:8761/eureka/
instance:
prefer-ip-address: true
3、啟動類
package com.feng;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.config.server.EnableConfigServer;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
@SpringBootApplication
@EnableEurekaClient
@EnableConfigServer
public class SpringCloud14ConfigServerApplication {
public static void main(String[] args) {
SpringApplication.run(SpringCloud14ConfigServerApplication.class, args);
}
}
4、測試服務器端
瀏覽器訪問 //localhost:8888/springcloud-config/config-base-local.yml
瀏覽器訪問個 server端口/應用名字/文件名-環境名.yml
3、config客戶端搭建並測試
1、pom.xml
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- Eureka client -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-client</artifactId>
</dependency>
<!--Spring Boot Actuator，感應服務端變化-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
</dependencies>
<dependencyManagement>
<dependencies>
<!-- SpringCloud 版本控制依賴 -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${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 可以配置多個配置
eureka:
client:
service-url.defaultZone: //127.0.0.1:8761/eureka/
instance:
prefer-ip-address: true
4、啟動類
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、測試類
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、測試客戶端
5、總結
springcloud config 本地化配置的優點是不需要另外搭建gitlab或者svn，部署相對簡單
缺點是 如果有多個server端需要手動同步文件，每一個服務器都需要有文件
