1、ConfigServer_8888配置中心

最初的时候，我讲ConfigServer的端口设置为5001，在url获取config配置中心的时候，没有任何问题，但是在ConfigClient使用服务中心的时候，发现了不论ConfigClient怎么配置，都是去寻找的默认的8888 Config配置中心。没办法，我总得测试呗，所以我将Config配置中心的端口改成了8888

网络传言

1、是Bootstrap，但是很明显，我的不是这个问题。

2、locahost域名的的问题，这种情况我还没试

1.1、添加pom依赖

<!--config-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-config-server</artifactId>
</dependency>


<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>com.healerjean.proj</groupId>
        <artifactId>hlj-parent</artifactId>
        <version>1.0.0-SNAPSHOT</version>
    </parent>

    <artifactId>hlj-config-5001</artifactId>
    <version>${project.healerjean.version}</version>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!--config-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-server</artifactId>
        </dependency>

        <!--lombok-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

1.2、启动类

@EnableConfigServer ：添加分布式配置服务端支持

package com.healerjean.proj;

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;

@EnableConfigServer //添加分布式配置服务端支持
@SpringBootApplication
public class ConfigServer_8888_Application {

    public static void main(String[] args) {
        SpringApplication.run(ConfigServer_8888_Application.class, args);
    }

}

2、Github存储配置信息

2.1、创建仓库cloud-config

2.1.1、根目录创建配置项目文件夹 config-client

1586936994852

2.1.2、创建配置文件properties

命名规则：自定义项目名称-profile.properties

1586937020658

client.properties

from=github-default

client-dev.properties

from=github-dev

client-local.properties

from=github-local

client-prod.properties

from=github-prod

2.1.3、上传到Github

1586937072702

2.2、Config配置中心配置

2.1.1、application.properties

spring.application.name=hlj-config-server
server.port=8888


# config => git仓库
spring.cloud.config.server.git.uri=https://github.com/HealerJean/cloud-config/
# 配置文件所属文件夹路径
spring.cloud.config.server.git.searchPaths=config-client
# 分支名称
spring.cloud.config.label=master
#公开仓库不需要写用户名和密码，如果是私有仓库则需要些用户名和密码
spring.cloud.config.server.git.username=
spring.cloud.config.server.git.password=

2.3、启动测试

2.3.1、http访问路径解释

application：properties代表的项目名

profile：properties代表的Profile

label：Gihub分支名称

http路径
/{application}/{profile}[/{label}]
/{label}/{application}-{profile}.yml
/{application}-{profile}.yml
/{application}-{profile}.properties 
http://localhost:8888/client/prod/master

接口返回：

        "prod"
    ],
    "label": "master",
    "version": null,
    "state": null,
    "propertySources": [
        {

                "from": "github-prod"
            }
        },
        {

            "source": {
                "from": "github-default"
            }
        }
    ]
}

                "from": "github-default"
            }
        }
    ]
