Sentinel configuration information is persisted to nacos (saved in the database)

Please see gitee for the entire project: https://gitee.com/xwb1056481167/spring-cloud

Sentinel installation and project integration: https://blog.csdn.net/www1056481167/article/details/113679945

Modify cloudalibaba-sentinel-service8401 project

1、jar包

<!-- alibaba sentinel -->
<dependency>
    <groupId>com.alibaba.csp</groupId>
    <artifactId>sentinel-datasource-nacos</artifactId>
</dependency>
<!-- alibaba nacos -->
<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
<!-- alibaba nacos sentinel -->
<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. Add a file in the nacos console

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

Description:
resource: resource name
limitApp: source application
grade: threshold type 0, thread number 1, QPS
count: stand-alone threshold
strategy: flow control mode, 0 means direct connection 1 means association 2 means link
controlBehavior: flow control effect, 0 fast Failure 1.
Means Warm Up, 2. Means waiting in line. ClusterMode: Whether the cluster is true, cluster is false, not cluster

Nacos configures the service name cloudalibaba-sentinel-service

The configuration is complete, and the /rateLimit/byUrl interface is accessed according to the rules, and the verification is successful
