Sentinel使用Nacos存储规则——普通服务
动态配置
推荐使用psuh模式，结合nacos使用
组件版本推荐
这里使用：
springboot 2.3.2.RELEASE
springcloud Hoxton.SR8
spring alibaba cluod 2.2.5.RELEASE
sentinel-datasource-nacos 1.8.0
sentinel 1.8.5
sentinel整合nacos
注解配置、控制台配置都无法解决配置丢失问题，通过Nacos配置中心解决该问题
下载源码：https://github.com/alibaba/Sentinel/archive/refs/tags/1.8.5.zip
-
修改pom.xml
将test这块注释掉 -
将test路径下的nacos文件夹拷贝到rule下
-
在配置文件中增加nacos配置
-
修改NacosConfig的配置
-
NacosConfigUtil注意groupid和后缀
-
修改规则方法的引用，新增nacos的方法
@Autowired
@Qualifier("flowRuleNacosProvider")
private DynamicRuleProvider<List<FlowRuleEntity>> ruleProvider;
@Autowired
@Qualifier("flowRuleNacosPublisher")
private DynamicRulePublisher<List<FlowRuleEntity>> rulePublisher;
- 修改sidebar.html文件
<li ui-sref-active="active" ng-if="entry.appType==0">
<a ui-sref="dashboard.flowV1({app: entry.app})">
<i class="glyphicon glyphicon-filter"></i> 流控规则 V1</a>
</li>
<li ui-sref-active="active" ng-if="!entry.isGateway">
<a ui-sref="dashboard.flow({app: entry.app})">
<i class="glyphicon glyphicon-filter"></i> 流控规则 Nacos</a>
</li>
-
修改 FlowServiceV1 为FlowServiceV2
-
修改flow_v2.html
-
打包
客户端集成
- pom.xml

- 在配置中心创建流控规则文件：sentinel-user-nacos-push-flow-rules
[
{
"clusterConfig":{
"acquireRefuseStrategy":0,
"clientOfflineTime":2000,
"fallbackToLocalWhenFail":true,
"resourceTimeout":2000,
"resourceTimeoutStrategy":0,
"sampleCount":10,
"strategy":0,
"thresholdType":0,
"windowIntervalMs":1000
},
"clusterMode":false,
"controlBehavior":0,
"count":1,
"grade":1,
"limitApp":"default",
"maxQueueingTimeMs":500,
"resource":"/test1",
"strategy":0,
"warmUpPeriodSec":10
}
]
注意：“limitApp”:“default”，这个参数默认为default
- 验证nacos里面是不是有
- sentinel 控制台是不是也有该规则
由于懒加载的方式，需要先访问服务才能显示
