应用错误收集

与Spring的控制器连接不起作用

标签： java spring

我尝试按照教程学习Spring。我使用Netbeans，看起来Spring没有“看到”控制器，但我在Apache日志中看不到任何有意义的错误。

每当我按下表单的提交按钮时，我都会收到404错误。我甚至在网上搜索过。我想了解错误，而不仅仅是复制和粘贴一些东西。

的index.jsp

<html>
<body>
<h2>Hello World!</h2>
<form action="add">
    <input type="text" name="t1"><br />
    <input type="text" name="t2"><br />
    <input type="submit">
</form>
</body>
</html>

ffuentese-servlet.xml中

您在web.xml中的配置不正确。

将网址格式从“ .htm”更改为“/ ”。这样，来自应用程序服务器的每个请求都将转发到Spring调度程序servlet。
