我得到以下错误：

我有这些。jar在我的WEB-INF/lib目录中

spring-beans-3.2.0.RELEASE.jar
spring-context-3.2.0.RELEASE.jar
spring-core-3.2.0.RELEASE.jar
spring-expression-3.2.0.RELEASE.jar
spring-webmvc-3.2.0.RELEASE.jar
spring-web-3.2.0.RELEASE.jar

我还需要什么

Answer 1

它应该是org.springframework.web.servlet.DispatcherServlet，包名中不带破折号。也许只是你的web.xml中的一个输入错误

Answer 2

可能导致异常的因素：

1. JAR不会添加到WEB-INF/lib目录中
2. DispatcherServlet引用未在web.xml中正确配置

你能上传网页吗。xml、项目结构和验证上述信息
