springmvc-环境准备

1.创建项目，打包方式设置为war

2.配置web.xml路径：D:\Code\spring\ssm2023\ssm2023\spring_mvc\src\main\webapp\WEB-INF\web.xml

 

3.引入pom依赖

<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">

web.xml的配置

 

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
