在 com.game.products.web.forms 包中新建 ProductsForm ，他继承了 ValidatorForm 。代码如下：

package com.game.products.web.forms;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.validator.ValidatorForm;
public class ProductsForm extends ValidatorForm {
// Fields
private String gameId; // 编号
private String gameNameCn; // 中文名称
private String gameNameEn; // 英文名称
private String gameCapacity; // 碟数
private String gameVersion; // 版本
private String gameMedia; // 介质
private String gameCopyright; // 版权
private String gamePrice; // 价格
private String gameContent; // 攻略
private String flag;
private String fieldname;
private String value;
// Constructors
public ProductsForm() {
gameId = null ;
gameNameCn = null ;
gameNameEn = null ;
gameCapacity = null ;
gameVersion = null ;
gameMedia = null ;
gameCopyright = null ;
gamePrice = null ;
gameContent = null ;
flag = null ;
fieldname = null ;
value = null ;
}
// reset
public void reset(ActionMapping mapping, HttpServletRequest request) {
gameId = null ;
gameNameCn = null ;
gameNameEn = null ;
gameCapacity = null ;
gameVersion = null ;
gameMedia = null ;
gameCopyright = null ;
gamePrice = null ;
gameContent = null ;
flag = null ;
fieldname = null ;
value = null ;
}
// Property accessors
public String getGameCapacity() {
return gameCapacity;
}
public void setGameCapacity(String gameCapacity) {
this .gameCapacity = gameCapacity;
}
public String getGameId() { return gameId;
}
public void setGameId(String gameId) {
this .gameId = gameId;
}
public String getGameNameCn() {
return gameNameCn;
}
public void setGameNameCn(String gameNameCn) {
this .gameNameCn = gameNameCn;
}
public String getGameNameEn() {
return gameNameEn;
}
public void setGameNameEn(String gameNameEn) {
this .gameNameEn = gameNameEn;
}
public String getGameVersion() {
return gameVersion;
}
public void setGameVersion(String gameVersion) {
this .gameVersion = gameVersion;
}
public String getGameMedia() {
return gameMedia;
}
public void setGameMedia(String gameMedia) {
this .gameMedia = gameMedia;
}
public String getFieldname() {
return fieldname;
}
public void setFieldname(String fieldname) {
this .fieldname = fieldname;
}
public String getFlag() {

}
public void setFlag(String flag) {

}

}
public void setGameContent(String gameContent) {

}
public String getGamePrice() {
return gamePrice;
}
public void setGamePrice(String gamePrice) {
this .gamePrice = gamePrice;
}
}
