一、springcloud-config文件的POM

<?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">
    <modelVersion>4.0.0</modelVersion>
 
    <groupId>com.tx</groupId>
    <artifactId>springcloud_config</artifactId>
    <version>1.0-SNAPSHOT</version>
    <modules>

        <module>config-client</module>
    </modules>
 
 
    <packaging>pom</packaging>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.1.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
 
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>

    </properties>
 
    <dependencies>
        <dependency>

                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
 
</project>
 
二、Server端 application.yml

spring:
  profiles:
     active: jdbc
  application:
     name: config-jdbc-server
  datasource:
     url: jdbc:mysql://127.0.0.1:3306/springcloud?useUnicode=true&characterEncoding=utf8&characterSetResults=utf8&serverTimezone=GMT%2B8
     username: root
     password: root
     driver-class-name: com.mysql.jdbc.Driver
  cloud:
     config:
       label: master
       server:
         jdbc: true
server:
  port: 8769
spring.cloud.config.server.jdbc.sql: SELECT key1, value1 from config_properties where APPLICATION=? and PROFILE=? and LABEL=?
三、client-config的配置文件 bootstrap.yml

spring:
  application:
    name: config-client
  cloud:
    config:
      uri: http://localhost:8769
      fail-fast: true
  profiles:
    active: dev
 
四：总结

/* 最终浏览器http://localhost:8762/foo * 根据配置文件，读取sever的8769端口 http://localhost:8769 * 然后sever端的8769端监听到，读取数据库的port，所以它自己就变成了8762端口 * */
