本文是本人在学习网络视屏springMVC的过程中的学习笔记。
为了更便于理解我决定从实际使用的角度解释。
我们在浏览器输入地址
http://localhost:8080/springMVC6/user/data/toUser
界面如下：
此时后台是跳转到下面class的toUser方法的
package com.tgb.web.controller.annotation;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("/user/data")
public class DataController {
@RequestMapping(value="/addUser")
public String addUser(String userName,String age,HttpServletRequest request){
request.setAttribute("userName", userName);
request.setAttribute("age", age);
String result ="this is addUser------";
return "userManager";
}
@RequestMapping(value="/delUser")
public String delUser(){
String result ="this is delUser------";
return "";
}
@RequestMapping(value="/toUser")
public String toUser(){
return "addUser";
}
}
addUser.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@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>
<script type="text/javascript" src="../js/jquery-1.7.1.min.js"></script>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
<script type="text/javascript">
function addUser(){
var form = document.forms[0];
form.action = "/springMVC6/user/data/addUser";
form.method="post";
form.submit();
}
</script>
</head>
<body>
<h>添加用户</h>
<form action="">
姓名：<input type="text" name="userName"/>
年龄：<input type="text" name="age"/>
<input type="button" value="添加" onclick="addUser()">
</form>
</body>
</html>当在界面输入“斯蒂芬”,点击“添加”，会调用/springMVC6/user/data/addUser，而此路径对应的是DataController的addUser方法。此方法通过request获取参数。
特别注意：
再输入中文的时候，后台接收回出现乱码。
这个时候需要在web.xml中配置字符过滤器
<!-- 强制转码 防止乱码出现 start --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <!-- 对那些文件转码 --> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 强制转码 防止乱码出现 end -->
<Connector URIEncoding="UTF-8" port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
