添加商品对象时报错

[迷失的国度]

java.lang.IllegalArgumentException: Cannot invoke com.yourcompany.struts.entity.Goods.setBeginTime - argument type mismatch

请高手帮忙解决下，感谢

[Vegertar]

它显示的是参数类型不匹配，楼主检查一下吧

[shyacinth]

参数类型不匹配

[feather41]

setbegintime的参数类型不匹配

[fansenhua]

不错！！！

我也知道是参数类型不匹配，
我把我的actionform和hbm.xml文件贴出来吧

actionform

public class GoodsForm extends ActionForm {
/*
* Generated Methods
*/

/**
* Method validate
* @param mapping
* @param request
* @return ActionErrors
*/
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
// TODO Auto-generated method stub
return null;
}

/**
* Method reset
* @param mapping
* @param request
*/
public void reset(ActionMapping mapping, HttpServletRequest request) {
// TODO Auto-generated method stub
}


private Goods item=new Goods();

public GoodsForm(){

if(item ==null){
item=new Goods();

}

item.setBuyer(new User());
item.setSaler(new User());

}


public Goods getItem() {
return item;
}

public void setItem(Goods item) {
this.item = item;
}
}

[lusifang]

property name="goodsName" type="java.lang.String"

把String 及下面对应的都改为小写试试

[台城柳月]

你把GoodsForm的beginTime类型改为String，
对数据库操作时做一下转换，
actionform 不能将例如"2009-05-20"这样的字符串自动转换为Date型

问题解决了，是我没有 输入日期导致的错误，谢谢各位
