每当尝试在浏览器中连接到我的 Controller 时，我都会收到空白页面。请求映射是正确的，我返回了正确的 jsp，但除了空白屏幕之外，浏览器上没有显示任何内容。
它似乎正在到达 Controller ，并且我没有收到任何错误。

JSP

pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>ProjectOne</title>
<link href="${pageContext.request.contextPath}/resources/css/welcome.css" rel="stylesheet" >
<h1>${greeting}</h1>
<br>

<body>

最佳答案
您正在发送 grettings 模型对象，但正在打印${greeting}。拼写不匹配。
关于java - 尝试访问返回 jsp 页面的 Controller 时出现空白页。一切都链接得很好，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29774353/
