java - spring mvc 示例中未找到 404 页面

Question

这个问题已经有答案了:

Why does Spring MVC respond with a 404 and report "No mapping found for HTTP request with URI [...] in DispatcherServlet"? (13 个回答)

已关闭 5 年前。

我正在开发 Spring 应用程序，我收到 404 页面未找到。

你使用 Controller 吗？通常情况下，浏览器调用WEB-INF目录下的页面是无法直接显示的。

您应该实现将返回“next”的 Controller ，以便它将解析为您的jsp。检查this tutorial了解更多详情
