public class UserGrant extends HttpServlet {

	@Override
	protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		//读出传递过来的授权id号
		String[] values=request.getParameterValues("power");
		//需要被授权的用户的id号
		int id=Integer.parseInt(request.getParameter("id"));
		//构造授权字符串
		StringBuffer sb=new StringBuffer();
		for(int i=0;i<values.length;i++){
			sb.append(values[i]);
			sb.append(",");
		}
		sb.deleteCharAt(sb.length()-1);
		//System.out.println(sb.toString());
		
		UsersDao udao=new UsersDao();
		Users user=(Users)udao.searchUsers(id);
		user.setPowerstr(sb.toString());
		udao.updateUsers(user);
		response.sendRedirect(request.getContextPath()+"/user/other.jsp");
