一、下载sentinel源码
https://github.com/alibaba/Sentinel
二、Sentinel控制台改造(sentinel-dashboard)
1、修改pom.xml(sentinel-dashboard) 找到 如下依赖 把test注释掉
<!-- for Nacos rule publisher sample -->
<dependency>
<groupId>com.alibaba.csp</groupId>
<artifactId>sentinel-datasource-nacos</artifactId>
<!--<scope>test</scope>-->
</dependency>
2、代码规则修改
1、修改之前参考一下官网的demo 路径如下：
sentinel-dashboard/src/test/java/com/alibaba/csp/sentinel/dashboard/rule/nacos
目录，将整个目录拷贝到
sentinel-dashboard/src/main/java/com/alibaba/csp/sentinel/dashboard/rule/nacos
修改 NacosConfig 工具类

修改 application.properties 增加如下
nacos.address=192.168.1.X:8848 nacos.namespace=XXXXXXXXXXXX
在com.alibaba.csp.sentinel.dashboard.util添加一个JSONUtils 工具类

公共部分目前修改完了 接下来是真正的规则设置修改
我们大概需要修改 五种规则设置 每种都需要修改 增加两个类文件 修改一个类文件分别是
FlowRuleNacosPublisher
FlowRuleNacosProvider
FlowControllerV1
【流控规则】 test工具类里面已经提供 我们直接修改即可
