Jodd是一个开源项目，http://jodd.sourceforge.net�Q?/span>有一个好用的jsp标签�Q�可以大大简化有表单输入�?/span>controller�?/span>

使用Jodd的优点：

1. ��化和�l�一controller�Q�抛�?/span>extends SimpleFormController�Q�统一使用implements Controller的方式�?/span>

2. ��?/span>JSP��面�?/span>bind,不需要一个字�D�一个字�D늚��l�定�?/span>

3. �?/span>bean没有��M��要求�Q�可以��用�Q意的bean做�ؓformBean.

使用�Ҏ��介：

�Q�．�?/span>jodd.jar攑ֈ�web-inf->lib下，�?/span>web.xml里声名标�{�：

<taglib>

       <taglib-uri>joddtaglib-uri>

       <taglib-location>/WEB-INF/lib/jodd.jartaglib-location>

    taglib>

�Q�．��L��的一�?/span>javaBean做�ؓFormBean

package caike;

public class User {

       private String userName;

       private String password;


       public String getPassword() {

              return password;

       }

       public void setPassword(String pwd) {

              this.password = pwd;

       }

       public String getUserName() {

              return userName;

       }

       public void setUserName(String username) {

              this.userName = username;

       }

}

�Q�．�?/span>JSP��面使用jodd tag:,比如对应用户��d��面�?/span>

<%@page import="caike.User"%>

<%@taglib uri="jodd" prefix="jodd"%>

<jodd:form beans="user" scopes="session">

<form action="my.htm" method="post" >

    <table width="300" border="0" cellspacing="0" cellpadding="0"

       align="center" class="white">

       <tr>

           <td height="32" align="right" width="107">用户名：td>

       <td height="32" width="193"><input type="text" name="userName"

              class="input" size="20"> td>

       tr>

       <tr>

           <td height="33" align="right" width="107">密码�Q?/span>td>

           <td height="33" width="193"><input type="password" name="password"

              class="input" size="21">td>

       tr>


        <tr>

           <td height="69" align="center" colspan="2">

            <input type="submit" name="Submit" value="��d��">

       tr>

    table>

form>

jodd:form>

�Q�．Dispatch-servelt.xml中对controller的配�|?/span>

不再需要这�U�方式：

�Q�．�?/span>controller中取�?/span>user

package caike;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import jodd.bean.BeanUtil;

import org.springframework.web.servlet.ModelAndView;

import org.springframework.web.servlet.mvc.Controller;

public class MyController implements Controller {

       public ModelAndView handleRequest(HttpServletRequest request,

                     HttpServletResponse response) throws Exception {

              User user = new User();

              BeanUtil.load(user, request);

              System.out.println("用户�?" + user.getUserName() + " 密码:" + user.getPassword());

              return null;

       }

}

需要注意的地方�Q?/span>

表单中对应的名字name�?/span>javaBean里对应的属性名要相同�?/span>

name="userName"

class="input" size="20">

public class User {

private String userName;

.......
