sentinel 規則持久化到nacos

問題描述

Sentinel Dashboard中添加的規則是存儲在內存中的，只要項目一重啓規則就丟失了git

此處將規則持久化到nacos中，在nacos中添加規則，而後同步到dashboard中；github

後面研究若是將dashboard中添加的規則自動添加到nacos中web

實現過程

1.導入依賴包json

<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app

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中添加規則spring-boot

[ { "resource": "/hello", "limitApp": "default", "grade": 1, "count": 5, "strategy": 0, "controlBehavior": 0, "clusterMode": false } ]

4.建立測試類測試

@RestController public class Test { @GetMapping("/hello") public String hello() { return "hello sentinel"; } }

訪問幾回接口以後，就能夠在Sentinel Dashboard 中看到在nacos中配置的規則信息了，而且項目服務重啓依然存在spa
