Sentinel: Sentinel 是什么 随着微服务的流行服务和服务之间的稳定性变得越来越重要https://gitee.com/mirrors/Sentinel.git
因为项目使用的是Spring-cloud-alibabaSentinel支持和nacos整合就持久化到nacos数据库中同时sentinel还能读取nacos中做的流控规则。 1 源码目录 1.1、后台源码修改
小惊喜sentinel中有和nacos中对接的源码只不过没有使用。
1、改成 默认后台使用sentinel对接nacos而不是存到内存
2、前台页面接口调用nacos对应的接口
1.1.1 sentinel-dashboard中需要改动的位置
pom.xml中将sentinel-datasource-nacos包的scope注释掉 1.1.2 源码持久化到nacos的实现位置
不多说先复制到main目录rule包下 nacos包中的4个类
FlowRuleNacosProvider 动态获取Nacos配置中心流控规则读取流控规则FlowRuleNacosPublisher publish上传流控规则到Nacos配置中心写入流控规则NacosConfig Nacos配置NacosConfigUtils 流控规则在nacos中配置文件的一些细节后缀、组别等
1.1.3 NacosConfig配置
只实现了本地nacos并且需要默认配置需要支持自定义配置 改造后 NacosConfig源码

}1.1.4 修改配置文件 application.properties
增加nacos配置信息
#Sentinel 连接nacos配置
sentinel.nacos.address 192.168.1.109:8848
sentinel.nacos.username nacos
sentinel.nacos.password nacos1.1.5 配置v2版本controller调用nacos提供的服务层 1.2 前端页面源码修改
1.2.1 配置中添加nacos接口并修改地址
文件 src/main/webapp/resources/app/scripts/controllers/identity.js
搜FlowServiceV1 改为 FlowServiceV2 搜/dashboard/flow/ 改为 /dashboard/v2/flow/ 1.2.2 修改页面中的路由地址
文件 src/main/webapp/resources/app/scripts/directives/sidebar/sidebar.html
搜dashboard.flowV1定位57行去掉V1 文件 src/main/webapp/resources/app/views/flow_v2.html
注释掉回到单机页面按钮 2.项目引用

以下文件后缀与组名需要对应 大功告成去试试效果吧
