SpringCloud之Sentinel监控初步使用...
Kite学习历程的第二十九天
目录
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!
