Spring MVC前台属性数据的传递和后台属性数据的接收
一、配置spring mvc
1、在web.xml文件中添加如下配置：
01.
<servlet>
02.
<servlet-name>MVCservlet-name>
03.
<servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
04.
<init-param>
05.
<param-name>contextConfigLocationparam-name>
06.
<param-value>/WEB-INF/mvc-config.xmlparam-value>
07.
init-param> 08.
servlet> 09.
<servlet-mapping>
10.
<servlet-name>MVCservlet-name>
11.
<url-pattern>*.dourl-pattern>
12.
servlet-mapping>2、mvc-config.xml文件配置
01.
"1.0" encoding="UTF-8"?> 02.
"http://www.springframework.org/schema/beans"03.
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
04.
xmlns:context="http://www.springframework.org/schema/context"
05.
xmlns:mvc="http://www.springframework.org/schema/mvc"
06.
xsi:schemaLocation="http://www.springframework.org/schema/beans
07.
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
08.
http://www.springframework.org/schema/tx
09.
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
10.
http://www.springframework.org/schema/context
11.
http://www.springframework.org/schema/context/spring-context-3.0.xsd
12.
http://www.springframework.org/schema/mvc
13.
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
14.
15.
package="cn.ecgonline.eis.controller." /> 16.
17.
18.
20.
21.
22.
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
23.
"prefix" value="/WEB-INF/http://www.it165.net/pro/webjsp/" target="_blank" class="keylink">jsp/" /> 24.
"suffix" value=".http://www.it165.net/pro/webjsp/" target="_blank" class="keylink">jsp" />25.
"viewClass"26.
value="org.springframework.web.servlet.view.JstlView" />
27.
28.
二、新建控制器类，获取前台属性值
我用的是annotation方式
1、后台用普通数据类型获取单个属性
控制器类：
01.
package cn.ecgonline.eis.controller.workstation;
02.
import org.springframework.stereotype.Controller;
03.
import org.springframework.web.bind.annotation.ModelAttribute;
04.
import org.springframework.web.bind.annotation.RequestMapping;
05.
import org.springframework.web.servlet.ModelAndView;
06.
/**
07.
* 测试
08.
* @author 陈文龙
09.
* @date 2013-9-13 下午12:49:53
10.
*/
11.
@Controller
12.
public class WrokstationController
13.
{
14.
@RequestMapping("/new_workstation.do")
15.
public ModelAndView newWorkStation(@RequestParam Stringusername){
16.
System.out.println(user.getUsername);
17.
ModelAndView mv = new ModelAndView("Hello");
18.
mv.addObject("test", "hello spring mvc!");
19.
return mv;
20.
}
21.
}
@RequestParam 注释表示 单个属性
jsp页面代码：
01.
<%@ page language="java" contentType="text/html; charset=utf-8"
02.
pageEncoding="utf-8"%>
03.
<%
04.
String path = request.getContextPath();
05.
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
06.
%>
07.
08.
<html>
09.
<head>
10.
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
11.
<title>Insert title heretitle>
12.
head> 13.
<body>
14.
<form action="<%=basePath%>/new_workstation.do" method="post">
15.
<input type="text" name="username">16.
<input type="submit" value="测试">
17.
form> 18.
body> 19.
html>二、后台用model类获取数据
Model类：
01.
package test;
02.
public class User
03.
{
04.
private String username;
05.
private String pass"http://www.it165.net/edu/ebg/" target="_blank" class="keylink">word;
06.
public String getUsername()
07.
{
08.
return username;
09.
}
10.
public void setUsername(String username)
11.
{
12.
this.username = username;
13.
}
14.
public String getPass"http://www.it165.net/edu/ebg/" target="_blank" class="keylink">word()
15.
{
16.
return password;
17.
}
18.
public void setPassword(String password)
19.
{
20.
this.password = password;
21.
}
22.
}
控制器类：
01.
package cn.ecgonline.eis.controller.workstation;
02.
import javax.annotation.Resource;
03.
import org.springframework.stereotype.Controller;
04.
import org.springframework.web.bind.annotation.ModelAttribute;
05.
import org.springframework.web.bind.annotation.RequestMapping;
06.
import org.springframework.web.servlet.ModelAndView;
07.
/**
08.
* 测试
09.
* @author 陈文龙
10.
* @date 2013-9-13 下午12:49:53
11.
*/
12.
@Controller
13.
public class WrokstationController
14.
{
15.
@RequestMapping("/new_workstation.do")
16.
public ModelAndView newWorkStation(@ModelAttribute User user){
17.
System.out.println(user.getUsername);
18.
System.out.println(user.getPassword);
19.
ModelAndView mv = new ModelAndView("Hello");
20.
mv.addObject("test", "hello spring mvc!");
21.
return mv;
22.
}
23.
}
@ModelAttribute 注解代表用模型来接收值，User对象里面的属性要和jsp页面的属性想对应。
jsp页面代码：
01.
<%@ page language="java" contentType="text/html; charset=utf-8"
02.
pageEncoding="utf-8"%>
03.
<%
04.
String path = request.getContextPath();
05.
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
06.
%>
07.
08.
<html>
09.
<head>
10.
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
11.
<title>Insert title heretitle>
12.
head> 13.
<body>
14.
<form action="<%=basePath%>/new_workstation.do" method="post">
15.
<table>
16.
<tr>
17.
<th>用户名：th>
18.
<td><input type="text" name="username">td>
19.
tr> 20.
<tr>
21.
<th>密码th>
22.
<td><input type="text" name="password">td>
23.
tr> 24.
table> 25.
<input type="submit" value="测试">
26.
form> 27.
body>
