无论何时使用创建web应用程序，都要在web.xml文件中为欢迎文件列表创建一个条目

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>


index.jsp

仔细遵循给定的教程并进行以下更改

读一下这个

当您单击此链接时，将生成新的GET请求并重定向到映射控制器

控制器

@控制器
@请求映射（“/welcome”）
公共类CrunchifyHelloWorld{
@RequestMapping（method=RequestMethod.GET）
公共字符串helloWorld（ModelMap模型，HttpServletRequest）{
String message=“
”+“Hello World，Crunchify.com提供的Spring 3.2.1示例
”；
消息+=“”；
//将消息添加到模块中
model.addAttribute（“消息”，消息）；
//要显示的jsp的名称
返回“欢迎”；
}
}

然后将调用helloWorld（）方法，该方法将把消息添加到ModelMap中，并向welcome.jsp文件发送请求

希望这对你有帮助

您是否已将index.jsp中的href值从welcome.html更改为welcome.jsp？并将该index.jsp移动到welcome.jsp存在的jsp文件夹请检查我的更新问题，我仍然收到相同的问题您可以使用MVCI提供一个hello word项目吗？您认为您的库中没有添加任何jar文件。在lib文件夹中添加以下jar，common-logging-x.x.jar jstl-x.x.jar spring-aspects-x.x.jar spring-beans-x.x.jar spring-context-x.x.jar spring-core-x.x.jar spring-expression-x.x.jar spring-webmvc-x.x.jar
