springboot+VUE+部署（1。新建项目）

说明：文章是在学习B站的"全网最简单但实用的SpringBoot+Vue前后端分离项目实战（第一季）"总结的笔记。
开发环境

IntelliJ IDEA 2025.1.4.1

JDK:17

mysql

Navicat Premium 16

Apipost

2。新建项目

3。修改application.yml内容：

复制代码

server:
  port: 9999

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/0813-demo?allowPublicKeyRetrieval=true&useUnicode=true&useSSL=false&characterEncoding=utf8&serverTimezone=Asia/Shanghai
    username: root
    password: 12345678


mybatis-plus:
  mapper-locations: classpath:mapper/*.xml  # 扫描 XML 文件
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl  # 打印 SQL

4。在pom.xml文件中加入mybatis-plus的依赖

5。测试代码是否正常

在浏览器中输入localhost:9999，若出现下图则说明一切正常。
