SpringCloud-config-service+Event-Bus+SVN实现自动更新配置.docx

1. 创建config service服务引入Maven包：dependency?groupIdorg.springframework.cloud/groupId?artifactIdspring-cloud-config-server/artifactId /dependency dependency?groupIdorg.springframework.cloud/groupId?artifactIdspring-cloud-starter-bus-amqp/artifactId?/dependency dependency?groupIdorg.springframework.boot/groupId?artifactIdspring-boot-starter-web/artifactId /dependencyperties## 刷新时，关闭安全验证management.security.enabled=false#########Rabbitmqspring.rabbitmq.host=22spring.rabbitmq.port=5672spring.rabbitmq.username=hjyspring.rabbitmq.password=hjyapplication.ymlserver: port: 7001spring: application: name: config-server cloud: config: enabled: true server: svn: uri: 39/svn/ username: gongzhong password: gongzhong searchPaths: springcloud #git: # uri: /pcf-guides/configuration-server-config-repo default-label: config profiles: active: subversion至此，config service 服务搭建完成。2. 给SVN服务器增加hook登录39服务器，进入svn的仓库目录下的hooks目录：/usr/svnrepos/hnapay2/hooks从post-commit.tmpl拷贝一份post-commit文件：cp post-commit.tmpl post-commit修改post-commit文件内容为：#!/bin/shcurl -X POST 52:7001/bus/refresh其中：52:7001为config-server的请求IP及端口修改post-commit文件为可执行文件：chmod +x post-commit到此就实现了配置中心的配置修改后，其他所有服务均自动重新获取配置。注意：只有引入了spring-cloud-starter-bus-amqp模块的服务才会重新获取配置============================================================扩展：为指定项目进行刷新原理：根据SVN的hooks获取到被update的配置文件目录，再通过/bus/refresh?destination=customers:**指令进行刷新要求：SVN的目录按serviceId命名，当然也可以在svn的hooks脚本中进行目录与server对应。如下图是我测试时的一个配置目录：其中：gateway与gateway服务同名，gateway-zuul与gateway-zuul服务同名修改hooks脚本为以下内容：#!/bin/shREPOS=$1REV=$2#通过look获取发生变更的文件目录SVNLOOK=/usr/bin/svnlook#发生变更的文件目录集合CHANGEDDIRS=$($SVNLOOK dirs-changed $REPOS)#发生变更的文件目录集合的第一条MASTERDIR=$(echo $CHANGEDDIRS | head -1)#循环while [ $CHANGEDDIRS != ];do?#获取最后一个目录名称，即服务名称?PROJECT=$(echo $MASTERDIR | awk -F / {print $(NF-1)})?echo $PROJECT /usr/svnrepos/hnapay2/hooks/logs?#发送刷新请求给config server?#将svn目录名称与服务名称对应?if [ $PROJECT = gateway ] ; then PROJECT=exp-gateway?fi?curl -X POST 52:7001/bus/refresh?destination=$PROJECT:**?#删除已经发送请求的?CH
