我已經創建了一個動態Web模塊項目usig STS和Spring MVC。問題是我向模型中添加了一個字符串,但它不能在使用EL的JSP頁面上顯示。JSP表達式語言錯誤
我可以知道它有什麼問題嗎?
下面是詳細信息: JSP頁面
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1" isELIgnored="false" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Spring MVC</title>
</head>
<body>
Home
<br />
<c:out value="${message}" />
</body>
</html>
的web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
MVC控制器:
@Controller
public class HomeController {
public HomeController() {
super();
}
@RequestMapping(value="/home", method=RequestMethod.GET)
public ModelAndView showHomePage() {
// View Name - Model Name - Model Data
return new ModelAndView("home", "message", "Hello Spring MVC");
}
}
調度 - servlet.xml中
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

我在我的構建路徑中有JSTL.jar。在Java構建路徑上找不到「c:out」(org.apache.taglibs.standard.tag.rt.core.OutTag)的標記處理程序類的警告消息
請幫助。
謝謝。
您的視圖解析器工作良好嗎?我的意思是你能看到這個jsp,然後你點擊'/ context/home'? –
發佈你的spring servlet context.xml來驗證你的ViewResolvers和View。 –
是,相應地顯示歡迎頁面。 – peterwkc
