当我单击 index.jsp 中的提交按钮时，我只是试图从 Controller.java 中显示 Hello World

【问题讨论】：

No mapping found for HTTP request with URI [/WEB-INF/pages/apiForm.jsp]的可能重复
我需要做哪些改变？
显然你在project-servlet.xml中缺少<mvc:annotation-driven />
NO 仍然显示相同的错误：警告：在 DispatcherServlet 中找不到带有 URI [/project/myMethod] 的 HTTP 请求的映射，名称为 'project'
现在没有错误但我找不到Hello World消息请帮助

【解决方案1】：

在你的web.xml看来你没有写

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>WEB-INF/project-servlet.xml</param-value>
</context-param>
