您是否在index.jsp中尝试了<a href="jsp/welcome.jsp">？你的href是相对的，所以基于你的目录结构，我希望welcome.jsp与index.jsp处于同一级别
|-- WEB-INF
|-- index.jsp
|-- welcome.jsp
您的结构似乎
|-- WEB-INF
|-- jsp
|-- welcome.jsp
|-- index.jsp
答案 1 :(得分：0)

tomcat找不到org.springframework.web.servlet.DispatcherServlet。
我认为你的包中没有spring-webmvc。
你需要确保包构建成功，并检查{tomcat webapps} / yourproject / WEB-INF / lib是否有spring-webmvc
答案 2 :(得分：-1)
您必须通过在web.xml中添加以下行来启动Spring容器
<!-- Creates the Spring Container shared by all Servlets and Filters -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:crunchify-servlet.xml</param-value>
</context-param>
确保crunchify-servlet.xml位于类路径的根目录。
