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

< taglib >

        < taglib-uri > jodd taglib-uri >

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

     taglib >

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

不再需要这�U�方式：

�Q?/span> �?/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;
.......
