一个超级简单的mvc,出了超级郁闷的问题,
jsp文件运行不报错,就是没任何显示
.do文件运行完java程序就问你是不是下载

---HelloController.java--

Java code

package test002;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.Controller;public class HelloController implements Controller{    private String viewPage;        public void setViewPage(String viewPage)    {        this.viewPage=viewPage;    }        public ModelAndView handleRequest(HttpServletRequest request,            HttpServletResponse response) throws Exception    {        System.out.println("**************");        String user=request.getParameter("user");        this.setViewPage("hello");        ModelAndView mav=new ModelAndView(viewPage,"user",user);        System.out.println(user+"------------");        return mav;    }}

--hello.jsp--

pageEncoding="utf-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>

<title>First Spring MVC</title>

</head>

<body>
<center>

<h1>
Hello,${user }!
</h1>
</center>
</body>
</html>

运行http://127.0.0.1/webTest/hello.do?user=aa的效果

[解决办法]
就是jsp有问题你把${user}去掉试一下
[解决办法]
看看标签里有没有全角空格
[解决办法]
[code=JSP]
<%@ page language="java" import="java.util.*"
contentType="texst/html;charset=utf-8"
pageEncoding="utf-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>

<title>First Spring MVC </title>

</head>

<body>
<center>
<h1>
Hello,${user }!
</h1>
</center>
</body>
</html>
[/code]
看不清重新贴一下
[解决办法]

XML code

<%@ page language="java" import="java.util.*"contentType="texst/html;charset=utf-8"pageEncoding="utf-8"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>     <title>First Spring MVC </title>  </head>   <body>    <center>    <h1>    Hello,${user }!    </h1>    </center>  </body></html>
[解决办法]
你没加 标签<%@ taglib uri="/WEB-INF/tld/c.tld" prefix="c"%>
[解决办法]
${user }要引进<%@ taglib uri="/WEB-INF/tld/c.tld" prefix="c"%>的
