集成
1、 创建一个父工程引入相关boot,cloud,alibaba依赖;
<properties>
<java.version>1.8</java.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<!--Spring-->
<spring.boot.version>2.3.4.RELEASE</spring.boot.version>
<spring.cloud.version>Hoxton.SR8</spring.cloud.version>
<spring.platform.version>Cairo-SR8</spring.platform.version>
<spring.cloud.alibaba.version>2.2.2.RELEASE</spring.cloud.alibaba.version>
</properties>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-alibaba-dependencies</artifactId>
<version>${spring.cloud.alibaba.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>${spring.boot.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring.cloud.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
1、 子项目添加pom;
<dependencies>
<!--启动依赖-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--test包-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<!--sentinel-->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
</dependency>
</dependencies>
1、 创建一个测试类;
2、 YML加入sentinel配置;
server:
port: 10000
spring:
application:
name: pearl-test-sentinel
cloud:
sentinel:
transport:
port: 8719
dashboard: localhost:8080
1、 启动项目,并访问测试接口,之后查看控制台;
简单流控规则示例
1、 找到测试接口;
2、 添加控制规则,此规则表示当前QPS限制为1![*][nbsp3];
3、 快速刷新当前页面,发现已被限流;
