sentinel 规则持久化到nacos

问题描述

Sentinel Dashboard中添加的规则是存储在内存中的，只要项目一重启规则就丢失了

此处将规则持久化到nacos中，在nacos中添加规则，然后同步到dashboard中；

后面研究如果将dashboard中添加的规则自动添加到nacos中

实现过程

1.导入依赖包

<parent>

        <groupId>org.springframework.boot</groupId>

        <artifactId>spring-boot-starter-parent</artifactId>

        <version>2.1.6.RELEASE</version>

        <relativePath/>

    </parent>

    <dependencyManagement>

        <dependencies>

            <dependency>

                <groupId>org.springframework.cloud</groupId>

                <artifactId>spring-cloud-dependencies</artifactId>

                <version>Greenwich.SR2</version>

                <type>pom</type>

                <scope>import</scope>

            </dependency>

            <dependency>

                <groupId>org.springframework.cloud</groupId>

                <artifactId>spring-cloud-alibaba-dependencies</artifactId>

                <version>0.9.0.RELEASE</version>

                <type>pom</type>

                <scope>import</scope>

            </dependency>

        </dependencies>

    </dependencyManagement>

    <dependencies>

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-web</artifactId>

        </dependency>

        <dependency>

            <groupId>org.springframework.cloud</groupId>

            <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>

        </dependency>

        <dependency>

            <groupId>com.alibaba.csp</groupId>

            <artifactId>sentinel-datasource-nacos</artifactId>

            <version>1.5.2</version>

        </dependency>

    </dependencies>

2.在application.properties中配置sentinel-nacos信息

spring.application.name=mz

server.port=8003

# sentinel dashboard

spring.cloud.sentinel.transport.dashboard=localhost:8080

spring.cloud.sentinel.datasource.ds1.nacos.server-addr=localhost:8848

spring.cloud.sentinel.datasource.ds1.nacos.data-id=mz-sentinel

spring.cloud.sentinel.datasource.ds1.nacos.group-id=DEFAULT_GROUP

spring.cloud.sentinel.datasource.ds1.nacos.data-type=json

spring.cloud.sentinel.datasource.ds1.nacos.rule-type=flow

3.在nacos中添加规则

[

    {

        "resource": "/hello",

        "limitApp": "default",

        "grade": 1,

        "count": 5,

        "strategy": 0,

        "controlBehavior": 0,

        "clusterMode": false

    }

]

4.创建测试类

@RestController

public class Test {

    @GetMapping("/hello")

    public String hello() {

        return "hello sentinel";

    }

}

访问几次接口之后，就可以在Sentinel Dashboard 中看到在nacos中配置的规则信息了，并且项目服务重启依然存在
