Sentinel結(jié)合Apollo實(shí)現(xiàn)規(guī)則持久化功能

概述：本文基于apollo熟練使用的小伙伴參考撕攒，因?yàn)楸疚臎](méi)有安裝啟動(dòng)apollo的步驟蒸苇，只提供apollo的對(duì)應(yīng)的appid和相應(yīng)的配置磷蛹，具體apollo部署及客戶端配置使用本文未提供，apollo相關(guān)依賴(lài)本文未提供溪烤；

本文使用：
spring-boot-2.6.8版本
spring-cloud-starter-alibaba-2021.0.1.0版本
sentinel-dashboard-1.8.3版本

一味咳、調(diào)整sentinel-dashboard源碼，調(diào)整步驟如下：

將test包中的apollo包移到rule包下面
將最外層pom文件中的sentinel-datasource-apollo依賴(lài)的范圍test注釋掉
修改apollo包下面的ApolloConfig類(lèi)檬嘀，修改apollo的地址和token （獲取apollotoken的方式在第"四"步）
修改apollo包下面的FlowRuleApolloProvider類(lèi)槽驶，修改apollo的appid和命名空間，都根據(jù)實(shí)際情況修改即可
修改apollo包下面的FlowRuleApolloPublisher類(lèi)枪眉，修改apollo的appid和命名空間，都根據(jù)實(shí)際情況修改即可
修改controller-v2包下面的FlowControllerV2類(lèi)再层，修改注入的規(guī)則了為apollo的

通過(guò)以上調(diào)整贸铜，sentinel-dashboard控制臺(tái)的包調(diào)整完成，重新打包部署就可以了聂受，下面展示apollo中的配置

移動(dòng)apollo包

注釋掉依賴(lài)的test

修改apollo地址和token

二蒿秦、apollo配置

spring.application.name = SentinelService
spring.cloud.sentinel.transport.dashboard = localhost:39999
spring.cloud.sentinel.log.dir = /logs

flowRules = [{"app":"SentinelService","clusterMode":false,"controlBehavior":0,"count":1,"gmtModified":1596855658214,"grade":1,"id":1,"limitApp":"default","resource":"/getMethod","strategy":0}]
degrades = [{"resource": "/getMethod","count": 50,"timeWindow": 5,"grade": 0},{"resource": "/getMethod","count": 5,"timeWindow": 8,"grade": 2},{"resource": "/erro","count": 0.5,"timeWindow": 5,"grade": 1}]
authoritys = [{"resource": "/getMethod","limitApp": "192.168.12.215","strategy": 1}]
paramflows = [{"resource": "/getMethod","grade": 1,"paramIdx": 1,"count": 10,"paramFlowItemList": []}]
systems = [{"qps": 20}]

三、客戶端服務(wù)配置

客戶端服務(wù)需添加的依賴(lài)：
pom文件配置

        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
            <version>2021.0.1.0</version>
        </dependency>

        <dependency>
            <groupId>com.alibaba.csp</groupId>
            <artifactId>sentinel-datasource-apollo</artifactId>
           <version>1.8.3</version>
            <exclusions>
                <exclusion>
                    <groupId>com.alibaba.csp</groupId>
                    <artifactId>sentinel-datasource-extension</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>com.alibaba.csp</groupId>
                    <artifactId>sentinel-core</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

yml文件配置

#Apollo配置
app:
  id: hse-backend2.0.0
apollo:
  meta: http://127.0.0.1:8080/
  bootstrap:
    enabled: true
    namespaces: sino-sentinel
env: dev

server:
  port: 39000

###應(yīng)用編碼配置
appCode: SentinelService

spring:
  application.name: SentinelService
  cloud:
    sentinel:
      log:
        dir: /logs
        switch-pid: true
      transport:
        dashboard: 127.0.0.1:39999
      datasource:
        flow: # 流控規(guī)則
          apollo:
            namespaceName: sino-sentinel
            flowRulesKey: flowRules
            rule-type: flow  #flow,degrade,authority,system, param-flow
        degrade: # 熔斷降級(jí)規(guī)則
          apollo:
            namespaceName: sino-sentinel
            flowRulesKey: degrades
            rule-type: degrade
        authority: # 授權(quán)規(guī)則  未驗(yàn)證,官方不推薦
          apollo:
            namespaceName: sino-sentinel
            flowRulesKey: authoritys
            rule-type: authority
        system: # 系統(tǒng)規(guī)則
          apollo:
            namespaceName: sino-sentinel
            flowRulesKey: systems
            rule-type: system
        param-flow: # 熱點(diǎn)規(guī)則
          apollo:
            namespaceName: sino-sentinel
            flowRulesKey: paramflows
            rule-type: param-flow

四蛋济、獲取apollo第三方接入的token

五棍鳖、查看結(jié)果

將sentinel控制臺(tái)啟動(dòng)，apollo服務(wù)啟動(dòng)及配置完成碗旅，客戶端服務(wù)啟動(dòng)渡处。然后訪問(wèn)客戶端服務(wù)的接口，即可在sentinel控制臺(tái)看到對(duì)應(yīng)的接口訪問(wèn)數(shù)據(jù)祟辟，同時(shí)也可以看到對(duì)應(yīng)的流控規(guī)則等其他在apollo配置的規(guī)則医瘫，也在sentinel控制臺(tái)上展示出來(lái)了
