springboot微服务

Question

win10使用sentinel,idea启动微服务注册成功但是实时监控和簇点链路都没有数据显示

启动命令如下

java -Dserver.port=8090 -Dcsp.sentinel.dashboard.server=localhost:8090 -Dproject.name=sentinel-dashboard -jar sentinel-dashboard.jar

以下为cmd输出日志

此为SentinelDashboard控制台的显示内容

在微服务中我使用了

        <java.version>1.8</java.version>
        <spring-boot.version>2.7.6</spring-boot.version>
        <spring-cloud.version>2021.0.5</spring-cloud.version>
        <spring-cloud-alibaba.version>2021.0.5.0</spring-cloud-alibaba.version>

       <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
        </dependency>

server:
  port: 5602
spring:
  application:
    name: fshop-cart
  cloud:
    sentinel:
      #取消懒加载
      eager: true
      #sentinel服务地址
      transport:

        clientIp: 10.225.196.74
      http-method-specify: true # 开启请求方式前缀
其余内容使用nacos进行加载无异常报错

让阿豪来帮你解答，本回答参考chatgpt3.5编写提供，如果还有疑问可以评论或留言

可能原因：

1. Sentinel dashboard未正确接入微服务
2. 微服务未正确配置Sentinel依赖或AOP切面 解决方案：
3. 确认启动Sentinel dashboard的命令是否正确，包括-Dcsp.sentinel.dashboard.server参数和端口号等
4. 确认微服务是否正确引入Sentinel依赖并开启AOP切面，示例代码如下： //pom.xml引入依赖 com.alibaba.cloud spring-cloud-starter-alibaba-sentinel //application.yml中开启aop spring: aop: auto: true proxy-target-class: true 如果以上步骤都正确无误，可以尝试重启微服务和Sentinel dashboard，或者确认Sentinel配置是否正确。也可以查看微服务的日志，看是否有相关报错信息。
