说明

用于分布式上所有微服务都连接到消息总线上面。进行统一的通知

Config动态刷新

configClient

configClient通过/actuator/bus-refresh端点通知消息总线 消息总线通知线上的所有服务实例 调用/actuator/refresh端点进行配置更新

configClient改造

1.增加bus pom依赖

 <!--根据消息总线实现所有服务配置刷新-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bus-amqp</artifactId>
</dependency>

2.配置文件增加mq信息

spring:
rabbitmq: #更多mq配置看书331页
username: liqiang
password: liqiang
host: localhost
port: 5672

3.配置文件增加bus端点

management:
endpoints:
web:
exposure:
include: refresh,bus-refresh

4.完整配置文件

spring:
application:
name: config #对应{application}
cloud:
config:
profile: dev #映射{profile}
label: master #映射{label}
#uri: http://127.0.0.1:7001 #config server地址
username: liqiang #configserver身份认证用户名
password: liqiang #configserver身份认证密码
discovery:
service-id: CONFIG-SERVER #configserver的服务名
enabled: true #开启通过服务访问configserver的功能
fail-fast: true #快速响应spring.cloud.config.fail-fast=true
retry:
multiplier: 1.1 #默认间隔乘数 如果间隔是1000 下一次间隔是1100
max-interval: 2000 #默认最大间隔数(毫秒)
max-attempts: 6 #默认重试次数
initial-interval: 1000 #默认间隔数
rabbitmq: #更多mq配置看书331页
username: liqiang
password: liqiang
host: localhost
port: 5672
server:
port: 7002
eureka:
instance:
hostname: localhost #当前实例的主机名字
client:
serviceUrl:
defaultZone: http://peer1:1111/eureka/, http://peer2:1112/eureka/
#http://127.0.0.1:7002/actuator/refresh
management:
endpoints:
web:
exposure:
include: refresh,bus-refresh

5.复制2个配置文件 分别命名为peer1和peer2并且将端口改为不一致

6.将client instail打包

8.执行eurekaserver    config-server    通过命令启动2个client

java -jar /Users/liqiang/Desktop/java开发环境/mavenRegitstory/com/liqiang/spring-cloud-config-client/0.0.1-SNAPSHOT/spring-cloud-config-client-0.0.1-SNAPSHOT.jar --spring.profiles.active=peer1
java -jar /Users/liqiang/Desktop/java开发环境/mavenRegitstory/com/liqiang/spring-cloud-config-client/0.0.1-SNAPSHOT/spring-cloud-config-client-0.0.1-SNAPSHOT.jar --spring.profiles.active=peer2

9.测试

post请求http://127.0.0.1:7003/actuator/bus-refresh 测试没通过 只有7003实现了刷新

PS:最终测试时版本文本 不确定是版本差异还是bug 修改版本 重新测试

   <parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<!--<version>2.1.0.RELEASE</version>-->
<version>2.0.3.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent> <properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
<!--<spring-cloud.version>Greenwich.M3</spring-cloud.version>-->
<spring-cloud.version>Finchley.RELEASE</spring-cloud.version>
</properties>

10.修改git 77777为88888

posman访问http://localhost:7002/actuator/bus-refresh

可以看到总线上的7003服务 也刷新了

configServer

我们可以发现 通知总线上所有实例刷新配置由configServer来负责会更合理

1.configServer增加pom依赖

 <!--根据消息总线实现所有服务配置刷新-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bus-amqp</artifactId>
</dependency>

2.配置文件增加mq以及端点

spring:
rabbitmq: #更多mq配置看书331页
username: liqiang
password: liqiang
host: localhost
port: 5672
management:
endpoints:
web:
exposure:
include: health,info,bus-refresh

3.刷新配置改为访问server的/actuator/bus-refresh 就可以了

指定服务刷新

http://localhost:7001/actuator/bus-refresh?destination=CONFIG:7002  为服务名字为config同时端口为7002的刷新

ps:没测试通过应该改为

http://localhost:7001/actuator/bus-refresh/config:7002 刷新名为config 同时端口为7002的服务

http://localhost:7001/actuator/bus-refresh/config:** 为刷新名为config的所有服务

事件跟踪

1.设置spring.cloud.bus.trace.enabled=true

2开启端点httptrace

management:
endpoints:
web:
exposure:
include: health,info,bus-refresh,httptrace,trace

3.访问http://localhost:7001/actuator/bus-refresh

4.再访问http://127.0.0.1:7001/actuator/httptrace

5.跟老版本的/trace地址不一样输出内容也不一样感觉不利于分析
