Spring Boot整合Mybatis Plus和Swagger2的教程详解

前言：如果你是初学者，请完全按照我的教程以及代码来搭建（文末会附上完整的项目代码包，你可以直接下载我提供的完整项目代码包然后自行体验！），为了照顾初学者所以贴图比较多，请耐心跟着教程来，希望这个项目Demo能给你一些帮助，如果觉得写的还可以请给个关注和点赞，谢谢！

题外话：这是我第一篇用markdown来写的博文，格式不好的地方请见谅

一、pom.xml和application.yml

1、pom.xml中添加相关依赖，这里我把我的pom.xml代码贴出来

<?xml version="1.0" encoding="UTF-8"?>

2、在resources下新建application.yml文件，并添加如下配置

# 配置端口
server:
 port: 8080

#----------------druid数据源配置-----------------------
spring:
 datasource:
 type: com.alibaba.druid.pool.DruidDataSource
 druid:
 #这里跟pom里面mysql-connector版本相关8.0之后用com.mysql.cj.jdbc.Driver，之前用com.mysql.jdbc.Driver
 driver-class-name: com.mysql.cj.jdbc.Driver
 #这里改成你自己的数据库名称以及账号和密码
 url: jdbc:mysql://127.0.0.1:3306/study?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowPublicKeyRetrieval=true
 username: root
 password: 123456
 initialSize: 10
 minIdle: 10
 maxActive: 30
 # 配置获取连接等待超时的时间
 maxWait: 60000
