本文是基于上一篇的基础之后进行，准备工作可参考上一篇
Sentinel下载地址(已修改)
修改NacosConfigUtil.java
添加代码：
public static final String DEGRADE_DATA_ID_POSTFIX = "-degrade-rules";
修改NacosConfig.java
添加代码：
@Beanpublic Converter<List<DegradeRuleEntity>, String> degradeRuleEntityEncoder() {return JSON::toJSONString;}@Beanpublic Converter<String, List<DegradeRuleEntity>> degradeRuleEntityDecoder() {return s -> JSON.parseArray(s, DegradeRuleEntity.class);}
添加DegradeRuleNacosProvider.java
在sentinel-dashboard下的**com.alibaba.csp.sentinel.dashboard.rule.nacos新建DegradeRuleNacosProvider.java

新建DegradeRuleNacosPublisher.java
在*com.alibaba.csp.sentinel.dashboard.rule.nacos新建DegradeRuleNacosPublisher.java
