关于intellij-idea:SpringClub07config-配置中心

一、 config 配置核心

yml 配置文件保留到 git 服务器，例如 github.com 或 gitee.com
微服务启动时，从服务器获取配置文件

1. 配置 config

1.1 新建config文件夹

1.2 将sp02,sp03,sp04,sp11四个我的项目的yml配置文件,复制到config我的项目,并改名

item-service-dev.yml
user-service-dev.yml
order-service-dev.yml
zuul-dev.yml

最初，清空四个我的项目中的application.yml文件

1.3 禁止配置核心的配置信息笼罩客户端配置

默认配置核心配置优先级高,配置核心配置会笼罩客户端的所有配置,包含命令行参数配置,这样咱们在item-service和order-service中配置的端口号启动参数会有效，所以咱们能够设置禁止配置核心的配置将客户端配置笼罩掉，在四个配置文件中增加上面的配置

spring:  application:    name: xxx  cloud:    config:      #避免配置核心的配置将客户端配置笼罩掉 override-none: true

1.4 将 config 我的项目上传到 gitee

2. 配置 config 服务器

config 配置核心从 git 下载所有配置文件。而其余微服务启动时从 config 配置核心获取配置信息。

2.1 新建 sp12-config 我的项目

2.2 增加依赖

pom.xml

<?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>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>2.2.1.RELEASE</version>        <relativePath/> <!-- lookup parent from repository -->    </parent>    <groupId>cn.tedu</groupId>    <artifactId>sp12-config</artifactId>    <version>0.0.1-SNAPSHOT</version>    <name>sp12-config</name>    <description>Demo project for Spring Boot</description>    <properties>        <java.version>1.8</java.version>        <spring-cloud.version>Hoxton.RELEASE</spring-cloud.version>    </properties>    <dependencies>        <dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-config-server</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-test</artifactId>            <scope>test</scope>            <exclusions>                <exclusion>                    <groupId>org.junit.vintage</groupId>                    <artifactId>junit-vintage-engine</artifactId>                </exclusion>            </exclusions>        </dependency>    </dependencies>    <dependencyManagement>        <dependencies>            <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>    <build>        <plugins>            <plugin>                <groupId>org.springframework.boot</groupId>                <artifactId>spring-boot-maven-plugin</artifactId>            </plugin>        </plugins>    </build></project>

2.3 批改 application.yml 文件

spring:  application:    name: config-server    cloud:    config:      server:        git:          uri: https://github.com/你的集体门路/sp-config          searchPaths: config          #username: your-username          #password: your-password    server:  port: 6001    eureka:  client:    service-url:      defaultZone: http://eureka1:2001/eureka, http://eureka2:2002/eureka

2.4 ### 主程序增加 `@EnableConfigServer` 注解

package cn.tedu.sp12;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.client.discovery.EnableDiscoveryClient;import org.springframework.cloud.config.server.EnableConfigServer;@EnableConfigServer@SpringBootApplicationpublic class Sp12ConfigApplication {    public static void main(String[] args) {        SpringApplication.run(Sp12ConfigApplication.class, args);    }}

2.5 启动，拜访测试

拜访 item-service-dev.yml 能够应用以下模式:
http://localhost:6001/item-service-dev.yml
http://localhost:6001/item-service/dev
测试其余文件
http://localhost:6001/user-service/dev
http://localhost:6001/zuul/dev
http://localhost:6001/order-service/dev

3. 配置 config 客户端

批改以下我的项目，从配置核心获取配置信息

sp02-itemservice
sp03-userservice
sp04-orderservice
sp11-zuul

3.1 增加 config 客户端依赖

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

3.2 在四个我的项目中增加 bootstrap.yml

bootstrap.yml，疏导配置文件，先于 application.yml 加载

item-service

#bootstrap.yml#1.eureka地址eureka:  client:    service-url:      defaultZone: http://eureka1:2001/eureka, http://eureka2:2002/eurekaspring:  cloud:    config:      discovery:        #2.从注册核心，发现配置核心 enabled: true        service-id: config-server        #3.从配置核心：下载 item-service-dev.yml name: item-service      profile: dev

zuul
