spring - 缺少的包org.springframework.web

Question

我继续学习Maven，并尝试理解为什么在pom中已经定义了org.springframework.web依赖时，为什么得到此错误包“org.springframework.web.servlet不存在”。

您能告诉我为什么会发生此错误吗？

Answer 1

org.springframework.web.servlet是Spring MVC的一部分，位于org.springframework:spring-webmvc Artifact 中:

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

org.springframework:spring-web包含在Web应用程序中使用Spring的常用功能，它与Spring MVC无关。
