Kite的学习历程SpringCloud之Sentinel监控初步使用

Kite学习历程的第二十九天

1.sentinel安装

1.1 下载

大部分都是在Github上进行下载，但是下载速度巨慢，而且有时下到一般会出现错误。所以我们可以在百度网盘找资源进行下载

1.2 运行

在cmd控制台输入：java -jar 文件名 进行运行

1.3 进行访问

访问：localhost:8080
账号密码都为：sentinel

2. 创建测试微服务cloudalibaba-sentinel-serverice8401

2.1 修改pom.xml引入依赖文件

<dependencies>
        <!--nacos依赖的引入-->

        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
        <!--后续做持久化会被用到-->
        <dependency>
            <groupId>com.alibaba.csp</groupId>
            <artifactId>sentinel-datasource-nacos</artifactId>
        </dependency>


        <!--SpringCloud ailibaba sentinel -->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
        </dependency>
        <!--openfeign-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
        </dependency>

        <!--引入自己创建的entities包-->
        <dependency>
            <groupId>cn.kitey.spring</groupId>
            <artifactId>cloud-api-commons</artifactId>
            <version>${project.version}</version>
        </dependency>
        <!-- SpringBoot整合Web组件+actuator -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <!--日常通用jar包配置-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
            <version>4.6.3</version>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

2.2 创建application.yml配置文件

sentinel：配置在让其受到监控

server:
  port: 8401

spring:
  application:
    name: cloudalibaba-sentinel-service
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
    sentinel:
      transport:
        dashboard: localhost:8080 #配置Sentinel dashboard地址
        port: 8719
management:
  endpoints:
    web:
      exposure:
        include: '*'

2.3 创建主启动类类

@SpringBootApplication
@EnableDiscoveryClient
public class sentinelMain8401 {

    public static void main(String[] args) {
        SpringApplication.run(sentinelMain8401.class, args);
    }
}

2.4 创建controller包，以进controller类

@RestController
@Slf4j
public class FlowLimitController {
    @GetMapping("/testA")
    public String testA()
    {
        log.info(Thread.currentThread().getName()+"\t"+"...testA");
        return "------testA";
    }

    @GetMapping("/testB")
    public String testB()
    {
        log.info(Thread.currentThread().getName()+"\t"+"...testB");
        return "------testB";
    }

}

3. 运行cloudalibaba-sentinel-serverice8401进行测试

访问地址：
http://localhost:8401/testB
http://localhost:8401/testA

查看sentinel控制台网站

测试成功！
