LiziForm是:

package web.form;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;

/**
* @author Administrator
*
* TODO 要更改此生成的类型注释的模板,请转至
* 窗口 - 首选项 - Java - 代码样式 - 代码模板
*/
public class LiziForm extends ActionForm{
private String userName=null;
private String passWord=null;
public String getUserName(){
return userName;
}
public void setUserName(String userName){
this.userName=userName;
}
public String getPassWord(){
return passWord;
}
public void setPassWord(String passWord){
this.passWord=passWord;
}
public void reset(ActionMapping mapping,HttpServletRequest request){
this.userName=null;
this.passWord=null;
}
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request){
ActionErrors errors=new ActionErrors();
if((userName==null)||(userName.length()<1)||(passWord==null)||passWord.length()<1)
errors.add("userName",new ActionMessage("no"));
return errors;
}
}
