## **修改cloudalibaba-sentinel-service8401项目** ##

1、jar包

<dependency>
        <groupId>com.alibaba.csp</groupId>
        <artifactId>sentinel-datasource-nacos</artifactId>
    </dependency>
    
    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
    </dependency>
    
    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
    </dependency>

2、application.yml

spring:
      cloud:
        sentinel:
          # 将sentinel的配置数据保存到nacos中
          datasource:
            ds1: #数据源1
              nacos:
                server-addr: localhost:8848
                dataId: cloudalibaba-sentinel-service
                groupId: DEFAULT_GROUP
                data-type: json
                rule-type: flow

3、在nacos控制台添加一下文件

[
        {
            "resource":"/rateLimit/byUrl",
            "limitApp":"default",
            "grade":1,
            "count":1,
            "strategy":0,
            "controlBehavior":0,
            "clusterMode":false
        }
    ]

说明：  
resource:资源名称  
limitApp: 来源应用  
grade: 阈值类型0、线程数1、QPS  
count： 单机阈值  
strategy： 流控模式，0表示直连1表示关联2表示链路  
controlBehavior: 流控效果，0快速失败1、表示Warm Up,2、表示排队等待  
clusterMode: 是否集群true集群false不集群

**nacos配置的是服务名cloudalibaba-sentinel-service**

配置完成，按照规则访问/rateLimit/byUrl接口，验证成功
