创建config-bus-server

1. 引入依赖

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

2. 创建启动类

@SpringBootApplication
@EnableConfigServer
@EnableDiscoveryClient
public class ConfigBusServerApplication {
    public static void main(String[] args) {
        new SpringApplicationBuilder(ConfigBusServerApplication.class)
                .web(WebApplicationType.SERVLET)
                .run(args);
    }
}

3. 新增application.yml配置文件

server:
  port: 60002
spring:
  application:
    name: config-bus-server
  rabbitmq:
    host: 43.142.15.107
    port: 5672
    username: guest
    password: guest
  cloud:
    config:
      server:
        git:
          uri: https://github.com/afterglow-now/config-repo.git
          # 强制拉去资源文件
          force-pull: true
          # 解决could not be established because of SSL problems错误
          skipSslValidation: true
eureka:
  instance:
    preferIpAddress: true
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
  client:
    service-url:
      defaultZone: http://localhost:20000/eureka/

management:
  security:
    enabled: false
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: always

4. 新增bootstrap.yml配置文件(加密相关)

encrypt:
  key: clay

创建config-bus-client

1. 引入pom依赖

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-config</artifactId>
    </dependency>
    <!--在SpringCloud 2020.* 版本把bootstrap禁用了，导致在读取文件的时候读取不到而报错-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-bootstrap</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <!-- rabbit mq 适配插件-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-bus-amqp</artifactId>
    </dependency>
    <!-- kafka mq 适配插件-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-bus-kafka</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    </dependency>
</dependencies>

2. 创建启动类

@SpringBootApplication
@EnableDiscoveryClient
public class ConfigBusClientApplication {
    public static void main(String[] args) {
        new SpringApplicationBuilder(ConfigBusClientApplication.class)
                .web(WebApplicationType.SERVLET)
                .run(args);
    }
}

3. yml配置文件

server:
  port: 61001

spring:
  application:
    name: config-bus-client
  rabbitmq:
    host: 43.142.15.107
    port: 5672
    username: guest
    password: guest
  cloud:
    # 引入多个binder需要指定默认的binder
    stream:
      default-binder: rabbit
    config:
      name: config-consumer
#      uri: http://localhost:60000
      discovery:
        enabled: true
        service-id: config-bus-server
      profile: dev
      label: main

eureka:
  instance:
    preferIpAddress: true
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
  client:
    service-url:
      defaultZone: http://localhost:20000/eureka/

management:
  security:
    enabled: false
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: always
myWord: ${word}

进行验证

1. 将config-bus-client启动多份
2. 访问两个连接验证结果
   • http://localhost:61001/refresh/word
   • http://localhost:61002/refresh/word
3. 对配置中心进行配置刷新
   • post请求发送none数据类型访问:http://localhost:60002/actuator/busrefresh
4. 访问2点进行验证
5. 将端口改为其中一个config-client的节点,对节点进行单独刷新,其他节点不受影响
   • http://localhost:61001/actuator/busrefresh
