构建模块

新建springcloud-config-server模块

• 引入pom文件：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<version>1.0-SNAPSHOT</version>
</parent> <modelVersion>4.0.0</modelVersion>

</dependency> </dependencies> </dependencyManagement>
<dependencies>
<!--SpringCloud 整合 config-server--> <dependency>

<artifactId>spring-cloud-config-server</artifactId>
</dependency>
<!--SpringCloud Eureka 客户端-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency> </dependencies>
<!--注意：这里必须添加，否则各种依赖有问题-->

<name>Spring Milestones</name>
<url>https://repo.spring.io/libs-milestone</url>
<snapshots> <enabled>false</enabled>
</snapshots> </repository> </repositories>
</project>

• application.yml配置文件：

##服务端口号
server:
port: 8888
eureka:
client:
service-url:
##当前服务注册到Eureka服务地址
defaultZone: http://localhost:8100/eureka,http://localhost:9100/eureka
register-with-eureka: true
## 需要检索服务信息
fetch-registry: true
## 服务注册名称
spring:
application:
name: config-server
cloud:
config:
server:
git:
#### config-server读取git环境地址
uri: https://gitee.com/svavo_admin/config.git
search-paths:
64. gkconfig
#### 读取分支环境
label: master

gitee --> 新建仓库-->新建文件夹 gkconfig

• AppConfigServer 启动类：

package com.baba.wlb;
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;
/**
78. @Author wulongbo
79. @Date 2021/1/27 14:57
80. @Version 1.0
*/@SpringBootApplication
@EnableEurekaClient
@EnableConfigServer
public class AppConfigServer {
public static void main(String[] args) {
SpringApplication.run(AppConfigServer.class,args);
}
}

启动项目

分别启动 Eureka Server,和 config-server。

码云gitee创建配置文件

命名规范

服务名称-环境.properties或者服务名称-环境.yml

创建配置文件

在gkconfig ，目录下面创建两个配置文件：

1. test-configClient-prd.properties

babainfo=pro.baba.znkj.com

2.test-configClient-sit.properties

babainfo=sit.baba.znkj.com

再次访问Eureka上的服务，


成功读取到gitee上面的配置文件信息！

config-client模块

构建springcloud-config-client

在这之前我们在gitee上新建两个项目需要用到的配置文件：

• pom依赖：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<dependencies>
<!--SpringCloud 整合 config-client--> <dependency>

</dependency>
<!--SpringCloud Eureka 客户端-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency> </dependencies>
<!--注意：这里必须添加，否则各种依赖有问题-->
<repositories>

<name>Spring Milestones</name>
<url>https://repo.spring.io/libs-milestone</url>
<snapshots> <enabled>false</enabled>
</snapshots> </repository> </repositories></project>

• bootstrap.yml配置文件：

##服务端口号
server:
port: 8883
eureka:
client:
service-url:
##当前服务注册到Eureka服务地址
defaultZone: http://localhost:8100/eureka,http://localhost:9100/eureka
register-with-eureka: true
## 需要检索服务信息
fetch-registry: true
## 服务注册名称
spring:
application:
#### 服务名称要和gitee上的配置文件服务名称一致
name: config-client
cloud:
config:
#### 读取版本环境
profile: sit
discovery:
#### config server 服务注册别名
service-id: config-server
#### 开启读取权限
enabled: true

• PropertyController控制页面：读取gitee配置信息

package com.baba.wlb.controller;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @Author wulongbo
* @Date 2021/1/27 16:06
* @Version 1.0
*/
@RestController
public class PropertyController {
@Value("${babainfo}")
private String babainfo;
@RequestMapping("/getBabainfo")
public String getBabainfo(){
return babainfo;
}
}

• 启动类AppConfigClient：

package com.baba.wlb;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
/**
* @Author wulongbo
* @Date 2021/1/27 16:09
* @Version 1.0
*/@SpringBootApplication
@EnableEurekaClient
public class AppConfigClient {
public static void main(String[] args) {
SpringApplication.run(AppConfigClient.class,args);
}
}

启动config-client

浏览器访问：http://localhost:8883/getBabainfo

成功读取到gitee上面的配置文件信息！
