快速搭建SpringBoot3+Prometheus+Grafana

一、搭建SpringBoot项目

1.1 创建SpringBoot项目

1.2 修改pom文件配置

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>

1.3 创建controller+service+mapper三层文件

1.3.1 controller

ArticleServiceImpl.java

import io.micrometer.core.annotation.Counted;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @BelongsProject: prometheus
 * @BelongsPackage: com.javagpt.prometheus.controller
 * @Author: JavaGPT
 * @CreateTime: 2024-10-23  00:01
 * @Description:
 * @Version: 1.0
 */
@RestController
@RequestMapping("/article")
public class c {

    @Counted(value = "article.get", extraTags = "get", description = "test")
    @GetMapping
    public String index() {

        return "Hello World";
    }
}

1.3.2 service

ArticleService.java

import com.javagpt.prometheus.entity.ArticleEntity;
import com.baomidou.mybatisplus.extension.service.IService;

/**
* @author 26314
* @description 针对表【tb_article】的数据库操作Service
* @createDate 2024-10-22 23:59:42
*/
public interface ArticleService extends IService<ArticleEntity> {

}

ArticleServiceImpl.java

import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.javagpt.prometheus.entity.ArticleEntity;
import com.javagpt.prometheus.service.ArticleService;
import com.javagpt.prometheus.mapper.ArticleMapper;
import org.springframework.stereotype.Service;

/**
* @author 26314
* @description 针对表【tb_article】的数据库操作Service实现
* @createDate 2024-10-22 23:59:42
*/
@Service
public class ArticleServiceImpl extends ServiceImpl<ArticleMapper, ArticleEntity>
    implements ArticleService{

}

1.3.3 mapper

ArticleMapper.java

import com.javagpt.prometheus.entity.ArticleEntity;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Mapper;

/**
* @author 26314
* @description 针对表【tb_article】的数据库操作Mapper
* @createDate 2024-10-22 23:59:42
* @Entity com.javagpt.prometheus.entity.ArticleEntity
*/
@Mapper
public interface ArticleMapper extends BaseMapper<ArticleEntity> {

}

1.3.4 mapper.xml

ArticleMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.javagpt.prometheus.mapper.ArticleMapper">

    <resultMap id="BaseResultMap" type="com.javagpt.prometheus.entity.ArticleEntity">
            <id property="id" column="id" jdbcType="INTEGER"/>
            <result property="webId" column="web_id" jdbcType="VARCHAR"/>
            <result property="articleId" column="article_id" jdbcType="VARCHAR"/>

            <result property="updater" column="updater" jdbcType="VARCHAR"/>
            <result property="remark" column="remark" jdbcType="VARCHAR"/>
    </resultMap>

    <sql id="Base_Column_List">
        id,web_id,article_id,
        author,title,abstract_content,
        content,tag,url,
        publish_time,comment_count,like_count,
        read_count,create_time,creator,
        update_time,updater,remark
    </sql>
</mapper>

1.4 修改application.yml 文件

spring:
  application:
    name: prometheus

  # mysql??
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.cj.jdbc.Driver

    password: root

management:
  endpoints:
    enabled-by-default: true #暴露所有端点信息
    web:
      exposure:
        include: '*'  #以web方式暴露


server:
  servlet:
    context-path: /prometheus
  port: 8080

# mybatisPlus配置
mybatis-plus:
  # mapper映射地址
  mapper-locations: classpath:mapper/*.xml
  # 实体类扫描包路径
  type-aliases-package: com.javagpt.prometheus.entity
  configuration:
    # sql打印
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
    # 开启驼峰命名
    map-underscore-to-camel-case: true
  global-config:
    db-config:
      # 数据库表前缀
      table-prefix: t_

1.5 一键启动

1.6 查看默认指标信息

本地访问 http://localhost:8080/prometheus/actuator/prometheus

二、搭建Prometheus

到官网下载最新版 https://prometheus.io/download/

修改Prometheus.yml文件

# my global config
global:
  scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
    - static_configs:
        - targets:
          # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"
    metrics_path: '/prometheus/actuator/prometheus' #指定抓取的路径
    static_configs:
      - targets: ['127.0.0.1:8080']
        labels:
          nodename: 'app-demo'
    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.
      # - targets: ["localhost:9090"]

CMD 进入命令行启动prometheus.exe

三、安装Grafana

3.1 下载

去官网下载最新版Garafana https://grafana.org.cn/grafana/download?platform=windows

3.2 安装

解压之后进入CMD命令行启动 grafana-server.exe

3.3 配置数据源

进入http://localhost:3000 登录，初始账号和密码都是admin，然后找到Data Source,进行如下操作，填好之后点击确认。

3.4 配置SpringBoot程序仪表盘模板

先进入Grafana官网寻找合适的SpringBoot程序模板 https://grafana.com/grafana/dashboards/?search=springboot ，然后将模板ID复制下来。

至此，整个SpringBoot3+Prometheus+Grafana就已经完成搭建啦。

让我们来看看最终的效果图吧。
