Sentinel 结合nacos 实现限流规则持久化

1.引入pom

<!-- 集成 Sentinel, 在网关层面实现限流 -->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-alibaba-sentinel-gateway</artifactId>
        </dependency>
<!-- Sentinel 使用 Nacos 存储规则 -->
        <dependency>
            <groupId>com.alibaba.csp</groupId>
            <artifactId>sentinel-datasource-nacos</artifactId>
        </dependency>

2.向sentinel dashboard 进行注册 dashboard需设置type

spring:
  application:
    name: e-commerce-gateway
  cloud:
    nacos:
      discovery:
        enabled: true # 如果不想使用 Nacos 进行服务注册和发现, 设置为 false 即可
        server-addr: 127.0.0.1:8848 # Nacos 服务器地址
        namespace: 1bc13fd5-843b-4ac0-aa55-695c25bc0ac6
#        metadata:
#          management:
#            context-path: ${server.servlet.context-path}/actuator
    sentinel:
      eager: true
      transport:
        port: 8720
        dashboard: 127.0.0.1:7777
      datasource:
