import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.wl.action.Action;
import com.wl.dao.SupplyDAO;
import com.wl.entity.Supply;

public class SupplySearchInfoAction implements Action {

	public String doExcute(HttpServletRequest request,
			HttpServletResponse response) {
		   String path;
			String id = request.getParameter("supplyid");//从页面上获取供应商编号
			SupplyDAO sdao = new SupplyDAO();
			List<Supply> list=sdao.selectSupplyId(id);//根据供应商编号查询供应商信息
			if(list.isEmpty()){
				System.out.print("_+++++++++++_________"+list);
				path="/admin/error.jsp";
			}else{
				request.getSession().setAttribute("list",list);
				System.out.print("_+++++++++++_________"+list);
				path= "/admin/supplycentershow.jsp";
