Your controller method is registered to accept GET requests on /output , while you're performing a GET request on /demoMVC/output . 你的控制器方法被注册为接受GET请求/output ，当你执行一个GET请求/demoMVC/output 。 Either modify your @RequestMapping value to /demoMVC/output , or change the URL you're calling in your browser. 将@RequestMapping值修改为/demoMVC/output ，或更改您在浏览器中调用的URL。

Furthermore, in many cases an InternalResourceViewResolver is configured to return the name of the JSP file without the .jsp suffix. 此外，在许多情况下， InternalResourceViewResolver配置为返回没有.jsp后缀的JSP文件的名称。 Assuming you've created a file named sampleOutput.jsp , adjust your karna() method to return "sampleOutput" instead of "sampleOutput.jsp" . 假设您已创建名为sampleOutput.jsp的文件，请调整karna()方法以返回"sampleOutput"而不是"sampleOutput.jsp" 。 If this does not work, would you be able to you post your InternalResourceViewResolver configuration? 如果这不起作用，您能否发布InternalResourceViewResolver配置？
