spring cloud config 简介

  • Spring Cloud Config为分布式系统中的外部化配置提供服务器和客户端支持。使用Config Server,您可以在所有环境中管理应用程序的外部属性。
  • Spring Cloud Config 分为两个部分 ,server端和client端。

      server端配置服务器,管理配置信息

      client端获取配置信息

创建并运行一个Spring Cloud Config Server

  • 创建一个名为config-server的应用,并添加spring-cloud-starter-parent,spring-cloud-config-server依赖,pom信息具体如下

  • 创建application主类,并添加@EnableConfigServer注解,代码如下

    复制代码

    package com.zcr.spring;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.config.server.EnableConfigServer;
    
    @SpringBootApplication
    @EnableConfigServer
    public class ConfigServerApplication {
        public static void main(String[] args) {
            SpringApplication.run(ConfigServerApplication.class,args);
        }
    }

    复制代码

  • 在本地创建一个配置文件db-service-dev.properties,格式如下

    复制代码

    sck.type=sck
    sck.url=jdbc:oracle:thin:@10.1.50.205:1521:orcl
    sck.class=oracle.jdbc.driver.OracleDriver
    sck.user=sddb
    sck.password=sddb
    eom.type=eom
    eom.url=jdbc:oracle:thin:@10.1.50.205:1521:orcl
    eom.class=oracle.jdbc.driver.OracleDriver
    eom.user=eom
    eom.password=eom

    复制代码

  • 在resources文件夹下创建application.properties,内容如下
    #tomcat端口号
    server.port=8888
    #配置文件在本地
    spring.profiles.active=native
    #配置文件的目录
    spring.cloud.config.server.native.search-locations=D:/workspace/GitHub/spring-config/config-file

创建并运行一个Spring Cloud Config Client

  • 创建一个名为config-client的应用,并添加spring-cloud-starter-parent,spring-cloud-starter-config,spring-boot-starter-web依赖,pom信息具体如下

    复制代码

    <?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"

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

    复制代码

  • 在resources中创建bootstrap.properties(bootstrap.yml会在应用启动之前读取),格式如下

    复制代码

    #文件名
    spring.application.name=db-service
    #文件模式,默认为default
    spring.cloud.config.profile=dev
    #server端ip地址
    spring.cloud.config.uri= http://localhost:8888/
    #client端ip端口
    server.port=8881

    复制代码

  • 创建一个controller

    复制代码

    package com.zcr.spring;
    
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @SpringBootApplication
    @RestController
    public class ConfigClientApplication {
        public static void main(String[] args) {
            SpringApplication.run(ConfigClientApplication.class, args);
        }
        @Value("${sck.user}")
        String sckUser;
        @Value("${sck.password}")
        String sckPassword;
    
        @RequestMapping("/hello")
        public String showUserAndPassword(){
            String sb = "username is " + sckUser + "," + "password is " +sckPassword;
            return sb;
        }
    }

    复制代码

  • 启动Application,并访问http://localhost:8881/hello,出现如下界面,成功
