我的来源
@RequestMapping(value = "/", method=RequestMethod.GET)
public ModelAndView mainPage() {
ModelAndView model = new ModelAndView("uploadPage");
model.addObject("msg", "hello world");
return model;
}
我的 web.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app PUBLIC

但是当执行“mainPage方法”时，jsp页面看起来像“text/plain”类型的源代码，而不是通常的页面...
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<%@ page isELIgnored="false" %>
<title>Hello Spring MVC</title>
</head>
<body>
<h2>
<c:out value="${msg}" />
</h2>
</body>
</html>
帮助
最佳答案
好吧，我想我明白了。更改
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
到这个
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*</url-pattern>
</servlet-mapping>
或
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
无论哪个适合您。致谢this answer .
