一、springboot3项目创建
在idea中创建springboot3项目后，主要的pom文件如下：
<?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"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>3.1.5</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.school.information</groupId><artifactId>school-information</artifactId><version>0.0.1-SNAPSHOT</version><name>school-information</name
)
