1.组件下载和启动
(1)sentinel-dashboard下载
(2)nacos下载
(3)jmeter下载
(4)redis下载(与流控关系不大,与项目启动有关)
2.本微服务项目启动三个子应用:gateway(网关)、auth(鉴权)和system(业务);
(1)gateway服务(流控的统一入口)
①pom.xml
②bootstrap.yml配置
③ruoyi-gateway-dev.yml
④启动类RuoYiGatewayApplication加入配置,否则在sentinel-dashboard主界面左侧无“API管理”菜单
⑤新增流控规则实时查询接口类“FlowRulesController”
⑥在sentinel-dashboard界面查看或者配置流控信息
⑦jmeter测试限流
⑧共享配置 application-dev.yml
(2)auth服务(鉴权)
①pom.xml
②bootstrap.yml配置
③ruoyi-auth-dev.yml
④启动类RuoYiAuthApplication无需处理
⑤登录系统后,sentinel-dashboard监控如下
(3)system服务(业务)
①pom.xml
②bootstrap.yml配置
③ruoyi-system-dev.yml
④启动类RuoYiSystemApplication显示API分组
⑤前端请求业务接口后,sentinel控制台显示
3.总结
1.组件下载和启动
(1)sentinel-dashboard下载
https://github.com/alibaba/Sentinel/releaseshttps://github.com/alibaba/Sentinel/releases
本案例使用sentinel-dashboard-1.8.4版本,
启动sentinel-dashboard服务,
java -Dserver.port=8718 -Dcsp.sentinel.dashboard.server=localhost:8718 -Dproject.name=sentinel-dashboard -Dcsp.sentinel.api.port=8719 -jar D:\sentinel-dashboard-1.8.4.jar
(2)nacos下载
发布历史 | Nacos 官网https://nacos.io/download/release-history/
本案例使用nacos-server-2.3.2版本,比较新的版本已经取消了登录功能,此处免密登录。
双击“nacos\bin\startup.cmd”,启动nacos服务,
(3)jmeter下载
Apache JMeter - Download Apache JMeterhttps://jmeter.apache.org/download_jmeter.cgi
本例使用apache-jmeter-5.5,
修改:apache-jmeter-5.5\bin\jmeter.properties,解决返回值中文乱码问题。
(4)redis下载(与流控关系不大,与项目启动有关)
https://github.com/MicrosoftArchive/redis/releaseshttps://github.com/MicrosoftArchive/redis/releases本案例使用Redis-x64-3.2.100
2.本微服务项目启动三个子应用:gateway(网关)、auth(鉴权)和system(业务);
最顶级pom.xml配置如下,主要是依赖包的版本控制;

④启动类RuoYiGatewayApplication加入配置,否则在sentinel-dashboard主界面左侧无“API管理”菜单
// sentinel显示API分组菜单
System.setProperty("csp.sentinel.app.type", "1");
⑤新增流控规则实时查询接口类“FlowRulesController”
用于实时查询通过sentinel-dashboard界面配置后的API分组信息和流控信息,然后可以回填到nacos对应的配置文件里,即可实现流控规则的持久化。
package com.ruoyi.gateway.controller;
import com.alibaba.csp.sentinel.adapter.gateway.common.api.ApiDefinition;
import com.alibaba.csp.sentinel.adapter.gateway.common.api.GatewayApiDefinitionManager;
import com.alibaba.csp.sentinel.adapter.gateway.common.rule.GatewayFlowRule;
import com.alibaba.csp.sentinel.adapter.gateway.common.rule.GatewayRuleManager;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.Set;
@RestController
public class FlowRulesController {
@GetMapping("/rule")
public Set<GatewayFlowRule> getGatewayFlowRules(){
return GatewayRuleManager.getRules() ;
}
@GetMapping("/api")
public Set<ApiDefinition> getApiGroupRules(){
return GatewayApiDefinitionManager.getApiDefinitions();
}
}
当在sentinel-dashboard界面配置好分组定义和限流策略后,将上面接口查到的实时限流内容,保存到nacos对应的json配置文件里,实现持久化,后面服务重启也不会丢失了,sentinel-dashboard永远显示的是最新的限流配置,包括nacos数据源里的配置和sentinel-dashboard界面的配置之和。
⑥在sentinel-dashboard界面查看或者配置流控信息
⑦jmeter测试限流
⑧共享配置 application-dev.yml

④启动类RuoYiSystemApplication显示API分组
// sentinel显示API分组菜单
System.setProperty("csp.sentinel.app.type", "1");
⑤前端请求业务接口后,sentinel控制台显示
请求链路可以作为gate限流时,API管理分组的路径参考,业务服务本身不作限流处理。
3.总结
springcloud项目的限流主要分为两种粒度,一是路由服务级别,二是API接口级别;统一通过gateway服务配置限流策略,其他需要限流的服务,只需要保证将自身的服务集成到sentinel和sentinel-dashboard即可,让sentinel控制台感知到API接口被访问即可。
gateway服务的pom.xml必须有依赖:
<!-- SpringCloud Alibaba Sentinel -->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
</dependency>
<!-- SpringCloud Alibaba Sentinel Gateway -->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-alibaba-sentinel-gateway</artifactId>
</dependency>
<!-- Sentinel Datasource Nacos -->
<dependency>
<groupId>com.alibaba.csp</groupId>
<artifactId>sentinel-datasource-nacos</artifactId>
</dependency>
其他业务服务限流只需下面依赖:
<!-- SpringCloud Alibaba Sentinel -->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
</dependency>
