用maven搭建spring开发环境为什么spring web 这个包是unknown module

用maven搭建spring开发环境为什么spring web 这个包是unknown module，不识别这个包，但是我是已经导进去了，换了3.2和4.2两个版本都是一样，运行的时候报错

这是怎么回事呢

1.改完pom.xml时记得update(项目名右键>maven>update project) 2.如果你使用的repository找不到可以换一个试试 3.mvc只需要这个dependency

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-webmvc</artifactId>
			<version>${spring-version}</version>
		</dependency>

maven会把相关的jar给你加载 4.示例
