过去几天我一直在面对这个问题，但仍然无法解决这个问题。我已经阅读了堆栈溢出中的所有先前答案。我在浏览器中找不到404文件，并且警告：在控制台中名称为“ firstOne”的DispatcherServlet中，使用URI [/ chaljayrr / add]的HTTP请求找不到映射。

答案 0 :(得分：0)
RequestMapping中提到的url是/add..try，使用浏览器/ REST客户端中的/ add。另外，在您的控制器方法中，只需返回“ display”。
由于已经配置了InternalResourceViewResolver的bean，它将自动找出jsp所在的路径-在您的情况下为/WEB-INF/display.jsp。
