【问题描述】:
我被困在这一点上,无法找到确切的原因。但是,我发现了许多类似的问题,但我的问题似乎仍然没有得到解决。我在 sts 4 中运行它并添加了一个 tomcat 服务器 9.0在本地运行它。我发现的最接近的问题是(org.springframework.web.servlet.PageNotFound noHandlerFound No mapping found for HTTP request with URI),但它似乎对我不起作用。下面是我的代码。

【问题讨论】:
-
你的WEB-INF/jsp/文件夹中有quotes.jsp吗?
-
@SujayMohan 是的,我在提到的文件夹中有quotes.jsp。
-
您要访问的网址是什么?也可以试试
<url-pattern>/</url-pattern> -
@SujayMohan localhost:8080/springMVCDemo/getQuote.html :这是我要调用的网址。
-
试试
