一、引入pom
代码语言：javascript复制<dependency>
<groupId>com.alibaba.csp</groupId>
<artifactId>sentinel-datasource-nacos</artifactId>
</dependency>二、配置文件添加sentinel数据源
代码语言：javascript复制server:
port: 8020
spring:
application:
name: order-service
cloud:
nacos:
config:
server-addr: 192.168.2.6:8001
group: DEFAULT_GROUP
prefix: order-service
file-extension: yaml
namespace: 9bb83945-f4a3-4839-8d3b-363f1b78db36
discovery:
server-addr: 192.168.2.6:8001
sentinel:
transport:
dashboard: 192.168.2.6:8858 #配置Sentinel dashboard地址
# 默认就是8719端口，如果占用会依次 1开始扫描
# 取消延迟加载
eager: true
datasource:
ds1:
nacos:
server-addr: 192.168.2.6:8001
namespace: 9bb83945-f4a3-4839-8d3b-363f1b78db36
dataId: ${spring.application.name}-sentinel
group: DEFAULT_GROUP
data-type: json
rule-type: flow三、nacos中添加规则
代码语言：javascript复制[
{
"resource": "getByOrderNo",
"limitApp": "default",
"grade": 1,
"count": 3,
"strategy": 0,
"controlBehavior": 0,
"clusterMode": false
}
]resource：资源名称 limitApp：来源应用 grade：阀值类型，0-线程数，1-qps count：单机阀值 strategy：流控模式，0-直接，1-关联，2-链路 controlBehavior：流控效果，0-快速失败，1-warm up，2-排队等待 clusterMode：是否集群
四、查看sentinel流控规则
五、接口调用测试
