22SpringMvc_jsp页面上的数据传递到控制器的说明

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;@Controllerpublic 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。
