Spring Cloud Bus消息总线+rabbitmq+Gradle(Greenwich.RELEASE版本)

作者:互联网

准备工作

环境以及版本:
说明

以下改造均在子项目进行操作,父项目的github地址,下述需下载父项目用来管理公共依赖:   https://github.com/cuifuan/springcloud-tools

1.改造你的 config-server

1.1 构建配置文件 build.gradle
dependencies {
    implementation "org.springframework.cloud:spring-cloud-config-server"
    implementation "org.springframework.cloud:spring-cloud-bus"
    implementation "org.springframework.cloud:spring-cloud-starter-bus-amqp"
}
1.2 配置文件 application.yml
server:
  port: 7001
spring:
  application:
    name: config-server
  cloud:
    config:
      server:
        git:
          uri: git地址 #例如https://github.com/cuifuan/springcloud-configuration.git
          search-paths: 仓库文件下文件夹
          default-label: master
          username: git账号
          password: git密码
    bus:
      trace:
        enabled: true
  rabbitmq:
    host: rabbitmq地址
    port: 5672
    username: rabbit账号【默认:guest】
    password: rabbit密码【默认:guest】
    virtual-host: /
eureka:
# 修改在服务中心的地址status为 ip+端口 【例如:10.0.0.100:88】
  instance:
    prefer-ip-address: true
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
  client:
    serviceUrl:
      defaultZone: http://springcloud-tools:8761/eureka/
info:
  app:
    description: This is Spring Cloud remote Registration center.
    name: tools-config-server
    version: 0.0
management:
  endpoint:
    bus-refresh:
      enabled: true
  endpoints:
    web:
      exposure:
        include: refresh,bus-refresh
1.3 启动类 ToolsConfigServerAppliaction.java
package store.zabbix.config;

import org.springframework.boot.SpringApplication;
import org.springframework.cloud.client.SpringCloudApplication;
import org.springframework.cloud.config.server.EnableConfigServer;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@EnableConfigServer
@SpringCloudApplication
@RestController
public class ToolsConfigServerAppliaction {

    public static void main(String[] args) {
        SpringApplication.run(ToolsConfigServerAppliaction.class, args);
    }

    @RequestMapping("/")
    public String home() {
        return "Hello World! My name is configserver.";
    }

}

2. 改造你的 config-client (客户端)

用来读取配置文件的

2.1 构建配置文件 build.gradle
dependencies {
    implementation 'org.springframework.cloud:spring-cloud-starter-config'
    implementation "org.springframework.cloud:spring-cloud-bus"
    implementation "org.springframework.cloud:spring-cloud-starter-bus-amqp"
}
2.2 配置文件 bootstrap.yml
spring:
  cloud:
    config:
      name: tools-config-client     #对应{application}部分
      profile: dev                  #对应{profile}部分
      #uri: http://localhost:8888/  #配置中心的具体地址
      label: master                 #对应git的分支。如果配置中心使用的是本地存储,则该参数无用
      discovery:
        enabled: true                 #开启Config服务发现支持
        service-id: config-server   #指定配置中心的service-id,便于扩展为高可用配置集群。
eureka:
  instance:
    prefer-ip-address: true
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
  client:
    service-url:
      defaultZone: http://springcloud-tools:8761/eureka/
2.2 配置文件 application.yml
server:
  port: 7003
spring:
  application:
    name: tools-config-client
  cloud:
    config:
  #配置重试机制
      retry:
        initial-interval: 2000
        max-attempts: 2000
        max-interval: 2000
        multiplier: 1.2
      fail-fast: true
    bus:
      #动态刷新配置
      refresh:
        enabled: true
      #跟踪总线事件
      trace:
        enabled: true
  rabbitmq:
    host: rabbitmq地址
    port: 5672
    username: rabbit账号【默认:guest】
    password: rabbit密码【默认:guest】
#配置actuator
# 1.X版本的springboot 配置: management.security.enabled=false  已经作废
#关闭安全认证
management:
  endpoint:
    bus-refresh:
      enabled: true
  #refresh接入点显式暴露出来
  endpoints:
    web:
      exposure:
        include: refresh,bus-refresh
2.3 启动类 ConfigClientApplication.java

注意:一定不要忘了加@RefreshScop注解

package store.zabbix.configreader;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
@RefreshScope
@EnableDiscoveryClient
public class ConfigClientApplication {

    /**     * http://localhost:8881/actuator/bus-refresh     */

    public static void main(String[] args) {
        SpringApplication.run(ConfigClientApplication.class, args);
    }

    @Value("${message}")
    String message;

    @GetMapping("/hello")
    public String getMessage(){
        return message;
    }

}

3.远程配置文件

4.操作流程

这个时候的读取的配置文件已发生变化

5.需要注意的坑
