struts2连接数据库时报错,Detected AnnotationActionValidatorManager, initializing it...
貌似是泛类型错误,具体的真的不知道是怎么回事

goodsAction

package sale.action;

import java.sql.SQLException;
import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.apache.struts2.ServletActionContext;

import sale.domain.Goods;
import sale.service.GoodsFacade;
import sale.service.GoodsFacadeImpl;



public class GoodsAction {

  private GoodsFacade goodsFacade;

Goods goods;
private int goodsId;
private List<Goods> list;
public GoodsAction() {
goodsFacade = new GoodsFacadeImpl();
}


public GoodsFacade getGFacade() {
return goodsFacade;
}


public void setGFacade(GoodsFacade facade) {
goodsFacade = facade;
}


public Goods getGoods() {
return goods;
}


public void setGoods(Goods goods) {
this.goods = goods;
}


public int getGoodsId() {
return goodsId;
}


public void setGoodsId(int goodsId) {
this.goodsId = goodsId;
}


public List<Goods> getList() {
return list;
}


public void setList(List<Goods> list) {
this.list = list;
}


public String addGoods() throws SQLException{

Goods goods=getGoods();
try{
goodsFacade.addGoods(goods);
setGoods(goods);
return"goodsSuccess";
}catch(Exception e){
e.printStackTrace();
return"goodsError";
}

}
