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

1.3 创建controller+service+mapper三层文件

1.3.1 controller

ArticleServiceImpl.java

importio.micrometer.core.annotation.Counted;importorg.springframework.web.bind.annotation.GetMapping;importorg.springframework.web.bind.annotation.RequestMapping;importorg.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")publicclass c {@Counted(value ="article.get", extraTags ="get", description ="test")@GetMappingpublicStringindex(){return"Hello World";}}

1.3.2 service

ArticleService.java

importcom.javagpt.prometheus.entity.ArticleEntity;importcom.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
*/publicinterfaceArticleServiceextendsIService<ArticleEntity>{}

ArticleServiceImpl.java

importcom.baomidou.mybatisplus.extension.service.impl.ServiceImpl;importcom.javagpt.prometheus.entity.ArticleEntity;importcom.javagpt.prometheus.service.ArticleService;importcom.javagpt.prometheus.mapper.ArticleMapper;importorg.springframework.stereotype.Service;/**

* @createDate 2024-10-22 23:59:42
*/@ServicepublicclassArticleServiceImplextendsServiceImpl<ArticleMapper,ArticleEntity>implementsArticleService{}

1.3.3 mapper

ArticleMapper.java

importcom.javagpt.prometheus.entity.ArticleEntity;importcom.baomidou.mybatisplus.core.mapper.BaseMapper;importorg.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
*/@MapperpublicinterfaceArticleMapperextendsBaseMapper<ArticleEntity>{}

1.3.4 mapper.xml

ArticleMapper.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPEmapperPUBLIC"-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mappernamespace="com.javagpt.prometheus.mapper.ArticleMapper"><resultMapid="BaseResultMap"type="com.javagpt.prometheus.entity.ArticleEntity"><idproperty="id"column="id"jdbcType="INTEGER"/><resultproperty="webId"column="web_id"jdbcType="VARCHAR"/><resultproperty="articleId"column="article_id"jdbcType="VARCHAR"/><resultproperty="author"column="author"jdbcType="VARCHAR"/><resultproperty="title"column="title"jdbcType="VARCHAR"/><resultproperty="abstractContent"column="abstract_content"jdbcType="VARCHAR"/><resultproperty="content"column="content"jdbcType="VARCHAR"/><resultproperty="tag"column="tag"jdbcType="VARCHAR"/><resultproperty="url"column="url"jdbcType="VARCHAR"/><resultproperty="publishTime"column="publish_time"jdbcType="TIMESTAMP"/><resultproperty="commentCount"column="comment_count"jdbcType="INTEGER"/><resultproperty="likeCount"column="like_count"jdbcType="INTEGER"/><resultproperty="readCount"column="read_count"jdbcType="INTEGER"/><resultproperty="createTime"column="create_time"jdbcType="TIMESTAMP"/><resultproperty="creator"column="creator"jdbcType="VARCHAR"/><resultproperty="updateTime"column="update_time"jdbcType="TIMESTAMP"/><resultproperty="updater"column="updater"jdbcType="VARCHAR"/><resultproperty="remark"column="remark"jdbcType="VARCHAR"/></resultMap><sqlid="Base_Column_List">

        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
    url: jdbc:mysql://106.55.xx.xx:3306/blog?serverTimezone=Asia/Shanghai&allowMultiQueries=true&rewriteBatchedStatements=trueusername: root
