1.搭建maven项目环境,略

2.创建maven项目

在这里插入图片描述
catalog选择interal,这样可以避免下载依赖卡死,并且创建更加迅速
在这里插入图片描述
创建的新项目jsp文件可能会报错 javax.servlet.http.HttpServlet
可以直接产出jsp文件,毕竟现在的系项目大多都是前后分离的,并且多数使用的vue,也可以添加一下依赖:

		<!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api -->
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>javax.servlet-api</artifactId>
			<version>4.0.1</version>
			<scope>provided</scope>
		</dependency>

如果没有java目录,可以新建一个

勾选上Main
在这里插入图片描述
如果想显示main层目录,可以将main移除掉

3.架构搭建

添加pom文件中的依赖项
添加properties

	<properties>
		<!-- spring版本号 -->
		<spring.version>4.0.2.RELEASE</spring.version>
		<maven.compiler.source>1.8</maven.compiler.source>
		<maven.compiler.target>1.8</maven.compiler.target>
	</properties>

添加spring核心依赖和一些其他常用依赖
