假设有这个一个业务：在jsp页面上写入数据，然后把这个数据传递到后台。
效果如下：
输入信息后点击确定，把这些信息保存到后台。
点击确定后。来到这里：
这就是效果。
-----------------------------------------------------------------------------------------------------------------------------------
我们给出具体的案例然后给出分析：
1.jFactoryCreate.jsp这个页面就是输入信息的页面。
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ include file="../../base.jsp"%>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
</head>
<body>
<form method="post">
<div id="menubar">
<div id="middleMenubar">
<div id="innerMenubar">
<div id="navMenubar">
<ul>
<li id="save"><a href="#"
onclick="formSubmit(‘insertfactory.action‘,‘_self‘);">确定</a></li>
<li id="back"><a href="list.action">返回</a></li>
</ul>
</div>
</div>
</div>
</div>
<div class="textbox" id="centerTextbox">
<div class="textbox-header">
<div class="textbox-inner-header">
<div class="textbox-title">新增厂家信息</div>
</div>
</div>
<div>
<div>
<table class="commonTable" cellspacing="1">
<tr>
<td class="columnTitle_mustbe">厂家名称：</td>
<td class="tableContent"><input type="text" name="fullName" /></td>
<td class="columnTitle_mustbe">厂家简称</td>
<td class="tableContent"><input type="text"
name="factoryName" /></td>
</tr>
<tr>
<td class="columnTitle_mustbe">联系人：</td>
<td class="tableContent"><input type="text" name="contacts" /></td>
<td class="columnTitle_mustbe">电话</td>
<td class="tableContent"><input type="text" name="phone" /></td>
</tr>
<tr>
<td class="columnTitle_mustbe">手机</td>
<td class="tableContent"><input type="text" name="mobile" /></td>
<td class="columnTitle_mustbe">传真</td>
<td class="tableContent"><input type="text" name="fax" /></td>
</tr>
<tr>
<td class="columnTitle_mustbe">验货员</td>
<td class="tableContent"><input type="text" name="inspector" /></td>
<td class="columnTitle_mustbe">排序号</td>
<td class="tableContent"><input type="text" name="orderNo" /></td>
</tr>
<tr>
<td class="columnTitle_mustbe">备注</td>
<td class="tableContent"><textarea name="cnote" style="height:120px;" ></textarea></td>
</tr>
</table>
</div>
</div>
</form>
</body>
</html>
上面的代码中有这么一句 onclick="formSubmit(‘insertfactory.action‘,‘_self‘);点击确定后就会来到insertfactory.action这里。
2.实体类 ：Factory 类：
package cn.itcast.jk.domain;
import java.util.Date;
import org.omg.CORBA.PRIVATE_MEMBER;
public class Factory {
private String id;
private String fullName;
private String factoryName;
private String contacts;
private String phone;
private String mobile;
private String fax;
private String cnote;
private String inspector;
private Integer orderNo;
private String createBy;
private String createDept;
private Date createTime;
/**
* @return the id
*/
public String getId() {
return id;
}
/**
* @param id the id to set
*/
public void setId(String id) {
this.id = id;
}
/**
* @return the fullName
*/
public String getFullName() {
return fullName;
}
/**
* @param fullName the fullName to set
*/
public void setFullName(String fullName) {
this.fullName = fullName;
}
/**
* @return the factoryName
*/
public String getFactoryName() {
return factoryName;
}
/**
* @param factoryName the factoryName to set
*/
public void setFactoryName(String factoryName) {
this.factoryName = factoryName;
}
/**
* @return the contacts
*/
public String getContacts() {
return contacts;
}
/**
* @param contacts the contacts to set
*/
public void setContacts(String contacts) {
this.contacts = contacts;
}
/**
* @return the phone
*/
public String getPhone() {
return phone;
}
/**
* @param phone the phone to set
*/
public void setPhone(String phone) {
this.phone = phone;
}
/**
* @return the mobile
*/
public String getMobile() {
return mobile;
}
/**
* @param mobile the mobile to set
*/
public void setMobile(String mobile) {
this.mobile = mobile;
}
/**
* @return the fax
*/
public String getFax() {
return fax;
}
/**
* @param fax the fax to set
*/
public void setFax(String fax) {
this.fax = fax;
}
/**
* @return the cnote
*/
public String getCnote() {
return cnote;
}
/**
* @param cnote the cnote to set
*/
public void setCnote(String cnote) {
this.cnote = cnote;
}
/**
* @return the inspector
*/
public String getInspector() {
return inspector;
}
/**
* @param inspector the inspector to set
*/
public void setInspector(String inspector) {
this.inspector = inspector;
}
/**
* @return the orderNo
*/
public Integer getOrderNo() {
return orderNo;
}
/**
* @param orderNo the orderNo to set
*/
public void setOrderNo(Integer orderNo) {
this.orderNo = orderNo;
}
/**
* @return the createBy
*/
public String getCreateBy() {
return createBy;
}
/**
* @param createBy the createBy to set
*/
public void setCreateBy(String createBy) {
this.createBy = createBy;
}
/**
* @return the createDept
*/
public String getCreateDept() {
return createDept;
}
/**
* @param createDept the createDept to set
*/
public void setCreateDept(String createDept) {
this.createDept = createDept;
}
/**
* @return the createTime
*/
public Date getCreateTime() {
return createTime;
}
/**
* @param createTime the createTime to set
*/
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
}
3.给出控制器的代码如下：
FactoryController.java:
package cn.itcast.jk.controller.basicinfo.factory;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import cn.itcast.jk.controller.BaseController;
import cn.itcast.jk.domain.Factory;
import cn.itcast.jk.service.FactoryService;
@Controller
public class FactoryController extends BaseController {
@Resource
FactoryService factoryService;
//保存新增加的数据
@RequestMapping("/basicinfo/factory/insertfactory.action")
public String insertfactory(Factory factory )
{
factoryService.insert(factory);
return "redirect:/basicinfo/factory/list.action";
}
}
这样就可以了.
但是好奇的是。我们在jFactoryCreate.jsp输入信息，fullName，contacts，phone等等这些信息，那么怎么把这些信息封装到
@RequestMapping("/basicinfo/factory/insertfactory.action")
public String insertfactory(Factory factory )
使factory这个类里面填好数据。
答案：我们在jsp页面上点击确定之后，根据"formSubmit(‘insertfactory.action‘,‘_self‘就能定位到public String insertfactory(Factory factory )这个方法，很明显就可以根据方法里面的参数Factory factory来注入数据。当然前提是jsp里面的input的name要和fatory这个实体类里面的属性名字要一模一样。
