一旦我们重启应用，Sentinel规则将消失，生产环境需要将配置规则进行持久化
将限流配置规则持久化进Nacos保存，只要刷新服务某个rest地址，sentinel控制台的流控规则就能看到，只要Nacos里面的配置不删除，针对服务上Sentinel上的流控规则持续有效
操作步骤：
1，添加jar
<dependency>
<groupId>com.alibaba.csp</groupId>
<artifactId>sentinel-datasource-nacos</artifactId>
</dependency>
添加Nacos规则
[
{
"resource":"/rateLimit/byUrl",
"limitApp":"default",
"grade":1,
"count":1,
"strategy":0,
"controlBehavior":0,
"clusterMode":false
}
]

测试，重启服务再访问接口测试。 |
