springcloud 配置中心git

一、通过客户端刷新，使配置文件生效

1、创建远程仓库，获取远程仓库地址（省略），application.yml

2、创建服务端工程

3、添加依赖

1<dependencies>
2        <dependency>
3            <groupId>org.springframework.cloud</groupId>
4            <artifactId>spring-cloud-config-server</artifactId>
5        </dependency>
6        <dependency>
7            <groupId>org.springframework.cloud</groupId>
8            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
9        </dependency>
10    </dependencies>

4、加注解

1@EnableDiscoveryClient
2@EnableConfigServer //激活对配置中心的支持
3@SpringBootApplication
4public class SpringCloudConfigServerMqApplication {
5
6    public static void main(String[] args) {
7        SpringApplication.run(SpringCloudConfigServerMqApplication.class, args);
8    }
9
10}

5、修改配置application.properties

1spring.application.name=spring-cloud-config-server
2server.port=8500
3
4spring.cloud.config.server.git.uri=https://***.git
5spring.cloud.config.server.git.username=***
6spring.cloud.config.server.git.password=***
7
8eureka.client.serviceUrl.defaultZone=http://**:***/eureka/

6、请求方式

11、application-{profiles}.yml请求
2http://192.168.0.131:8500/application-local.yml
3http://192.168.0.131:8500/application-test.yml
4http://192.168.0.131:8500/application-prod.yml
52、application/{profiles}/{lable}
6http://192.168.0.131:8500/application/local/master
7http://192.168.0.131:8500/application/test/master
8http://192.168.0.131:8500/application/prod/master
93、{lable}/application-{profiles}.yml
10http://192.168.0.131:8500/master/application-local.yml
11http://192.168.0.131:8500/master/application-test.yml
12http://192.168.0.131:8500/master/application-prod.yml

7、创建客户端工程

8、添加依赖

1<dependency>
2            <groupId>org.springframework.cloud</groupId>
3            <artifactId>spring-cloud-starter-config</artifactId>
4        </dependency>
5        <dependency>
6            <groupId>org.springframework.cloud</groupId>
7            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
8        </dependency>

9、加注解

1@SpringBootApplication
2@EnableDiscoveryClient
3public class SpringCloudProviderDynastyMqApplication {
4
5    public static void main(String[] args) {
6        SpringApplication.run(SpringCloudProviderDynastyMqApplication.class, args);
7    }
8
9}

10、修改配置bootstrap.yml

1spring:
2  application:
3    name: dynasty
4  cloud:
5    config:
6      uri: http://192.168.0.131:8500
7      profile: prod
8      label: master
9management:
10  endpoints:
11    web:
12      exposure:
13        include: refresh,health,info

11、发送请求

12、修改远程仓库的值，使用postman刷新

此种刷新方式的缺点在于：配置文件有变化时，需要客户端主动刷新，当客户端有很多时，刷新不是很方便，，希望有一种方式可以通过服务端刷新

二、使用kafka通过刷新服务端来使配置生效

 　　1、服务端修改

　　　　1.1新增依赖

1　　　　 <dependency>
2            <groupId>org.springframework.boot</groupId>
3            <artifactId>spring-boot-starter-actuator</artifactId>
4        </dependency>
5        <!-- kafka依赖 -->
6        <dependency>
7            <groupId>org.springframework.cloud</groupId>
8            <artifactId>spring-cloud-starter-bus-kafka</artifactId>
9        </dependency>

　　　　1.2修改配置

1eureka:
2    client:
3      serviceUrl:
4        defaultZone: http://ip:port/eureka/
5server:
6  port: 8500
7spring:
8  application:
9    name: spring-cloud-config-server-mq
10  cloud:
11    config:
12      server:
13        git:
14          uri: https://giturl.git
15          username: username
16          password: password
17    bus:
18      enabled: true
19    stream:
20      kafka:
21        binder:
22          brokers: 192.168.0.128:9092,192.168.0.129:9092,192.168.0.130:9092
23management:
24  endpoints:
25    web:
26      exposure:
27        include: "*"

　　　　1.3启动项目

　　2、客户端修改

　　　　2.1添加依赖

1<dependency>
2        <groupId>org.springframework.cloud</groupId>
3        <artifactId>spring-cloud-starter-bus-kafka</artifactId>
4</dependency>

　　　　2.2修改配置

1spring:
2  application:
3    name: dynasty
4  cloud:
5    config:
6      uri: http://192.168.0.131:8500
7      profile: prod
8      label: master
9    bus:
10      enabled: true
11  kafka:
12    bootstrap-servers: 192.168.0.128:9092,192.168.0.129:9092,192.168.0.130:9092

　　　　2.3启动项目

　　3、请求示例

 　　　　3.1git配置

 　　　　3.2请求

　　　　3.3修改git配置

　　　　3.4调用刷新接口

　　　　3.5再次请求
