如何运行

1.首先确保你是JDK17(SpringBoot2.7需要JDK11,SpringBoot3需要JDK17)，推荐微软的MSJDK17

2.使用Maven安装类库，国内推荐使用阿里云Maven镜像，mvn clean compile

3.使用比较新版本的PostgreSQL，作者本地为V16

4.项目已配置新版的SpringBoot3.3，需要2.7X版本请从SpringBoot2分支中提取

5.导入D:\Workspace\Project\MySpringBootAPI\src\main\resources\SQL\public.sql到你的数据库去，新建一个叫TEST的空白数据库，编码UTF8

6.找到Application，运行项目

Upgrade Issue Resolution 升级问题解决方案

如果你最近也在升级FastJson到FastJson2版本，而跟我一样也遇到了FastJsonHttpMessageConverter找不到类问题以及FastJsonConfig找不到问题，那么恭喜你，看完本文，安装完fastjson2、fastjson2-extension、fastjson2-extension-spring6这三个类库，你就可以成功使用新版FastJson2了。 FastJson2中FastJsonHttpMessageConverter找不到类问题
当项目从2.7.x的springboot升级到3.0.x的时候，遇到一个问题"java: 程序包javax.servlet.http不存在" 问题： java: 程序包javax.servlet.http不存在
