Question

我继续学习maven并尝试理解为什么当org.springframework.web dependecy已经在pom中定义时，我得到这个错误包“org.springframework.web.servlet不存在”。

  <version>1.0-SNAPSHOT</version>

</dependency>
<dependency>

  <artifactId>junit</artifactId>
  <version>3.8.1</version>
  <scope>test</scope>
</dependency>

你能告诉我为什么会出现这个错误吗？

Answer 1

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

<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。

Answer 2

将此依赖项添加到您的pom.xml

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>3.1.1.RELEASE</version>
</dependency>

缺少的包org.springframework.web
