1.1 直接到Sentinel官网里的releases下即可下载最新版本Sentinel官方下载地址直接下载jar包即可。不过慢可能下载不下来 1.2 可以去gitee去下载jar包
1.3 下载完成后进行打包 1.4 执行命令
打开命令行窗口进入到项目里面执行
mvn clean package -DskipTests2、打包完成后直接启动
java -jar sentinel-dashboard.jar3、启动成功
4、web页面
浏览器输入localhost:8084
账号密码sentinel5、编写项目导入pom依赖
?xml version1.0 encodingUTF-8?
project xmlnshttp://maven.apache.org/POM/4.0.0xmlns:xsihttp://www.w3.org/2001/XMLSchema-instancexsi:schemaLocationhttp://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsdmodelVersion4.0.0/modelVersiongroupIdorg.example/groupIdartifactIdsentinel/artifactIdversion1.0-SNAPSHOT/versionpropertiesmaven.compiler.source8/maven.compiler.sourcemaven.compiler.target8/maven.compiler.targetproject.build.sourceEncodingUTF-8/project.build.sourceEncoding/propertiesparentgroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-parent/artifactIdversion2.2.7.RELEASE/versionrelativePath//parentdependenciesdependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web/artifactIdversion2.2.4.RELEASE/version/dependencydependencygroupIdorg.mybatis.spring.boot/groupIdartifactIdmybatis-spring-boot-starter/artifactIdversion1.3.2/version/dependencydependencygroupIdcom.alibaba.cloud/groupIdartifactIdspring-cloud-starter-alibaba-sentinel/artifactIdversion2.2.5.RELEASE/version/dependency/dependencies
/project6、新建application.yml文件
server:port: 8001
spring:application:name: sentinel-servicecloud:sentinel:transport:dashboard: localhost:8084eager: true
management:endpoint:web:exposure:include: *7、新建启动类
package com.xxx;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;SpringBootApplication(exclude DataSourceAutoConfiguration.class)
public class SentinelServiceApplication {public static void main(String[] args) {SpringApplication.run(SentinelServiceApplication.class,args);}
}8、新建controller
package com.xxx.controller;import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;RestController
RequestMapping(value test)
public class TestController {GetMapping(value /a)public String test1() {return Hello,Sentinel -- 1;}GetMapping(value /b)public String test2() {return Hello,Sentinel -- 2;}
}9、启动项目调用接口
http://localhost:8001/test/a
http://localhost:8001/test/b
有的时候在Sentinel控制台的簇点链路只显示/error和/**无法显示相应的资源
解决方式将这个依赖版本升级为2.2.5 即可dependencygroupIdcom.alibaba.cloud/groupIdartifactIdspring-cloud-starter-alibaba-sentinel/artifactIdversion2.2.5.RELEASE/version/dependency10、现在给/test/a限流
点击流控按钮新增流控规则即可
11、页面展示
连续点击三次就会出现限流操作至此 搭建完成。。。
