# 1.前言 #

当服务非常多的时候，一处配置修改，我们就要将所有相同服务的配置修改，这样的话就是非常繁琐的，我们引入配置中心，一处修改，处处生效。

# 2.创建blog\_config模块 #

（1）添加pom文件

<dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-bus-amqp</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-config</artifactId>
            </dependency>
            <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-actuator</artifactId>
            </dependency>
        </dependencies>

（2）添加主配置类

@SpringBootApplication
    @EnableConfigServer
    @EnableDiscoveryClient
    public class BlogConfig {
        public static void main(String[] args) {
            SpringApplication.run(BlogConfig.class, args);
        }
    }

（3）application.properties文件

server.port=6001
    
    spring.application.name=blog-config
    
    eureka.client.service-url.defaultZone=http://localhost:7001/eureka/
    eureka.instance.prefer-ip-address=true
    
    spring.cloud.config.server.git.uri=https://github.com/sustly/blog_config.git
    spring.cloud.config.label=master
    spring.cloud.config.server.git.search-paths=blog_config
    
    management.endpoints.enabled-by-default=true
    management.endpoint.health.show-details=always
    #management.endpoints.web.exposure.include=refresh,info,health
    management.endpoints.web.exposure.include=*
    
    spring.rabbitmq.host=localhost
    spring.rabbitmq.port=5672
    spring.rabbitmq.username=guest
    spring.rabbitmq.password=guest

注意：这里使用的github的方式，拉取配配置。

# 3.其他模块配置修改 #

（1）pom

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

(2)application.properties

spring.cloud.config.label=master
    spring.cloud.config.name=blog
    spring.cloud.config.profile=dev
    spring.cloud.config.uri=http://localhost:6001
    
    spring.rabbitmq.host=localhost
    spring.rabbitmq.port=5672
    spring.rabbitmq.username=guest
    spring.rabbitmq.password=guest

注意：config.uri是配置中心地址，label是github分支,profile是文件名-后面，name是文件名-前面

启动项目后：修改github

发送curl -X POST "http://配置中心地址:端口/actuator/bus-refresh"即可全部更新配置
