request.setAttribute(\, list);

request.getRequestDispatcher(\).forward(request,

response);

private void doLnquiresGYS(HttpServletRequest request,

HttpServletResponse response)throws ServletException,IOException { List list=oper.GYSLnquires(); if(list!=null){

request.setAttribute(\, list);

request.getRequestDispatcher(\).forward(request,

}

}else { }

response.sendRedirect(\);

response);

}

}else { }

response.sendRedirect(\);

如图 4-7

代码：

private void doGYSAdd(HttpServletRequest request,

HttpServletResponse response) throws ServletException,IOException{ String gys_id = request.getParameter(\).trim(); String gys_name =request.getParameter(\).trim(); String gys_miaoshu=request.getParameter(\).trim(); String gys_lianxiren=request.getParameter(\).trim(); String gys_phone=request.getParameter(\).trim(); String gys_chuanzhen=request.getParameter(\).trim(); String gys_address=request.getParameter(\).trim(); List params = new ArrayList(); params.add(gys_id); params.add(gys_name); params.add(gys_miaoshu); params.add(gys_lianxiren); params.add(gys_phone); params.add(gys_chuanzhen); params.add(gys_address); 23

Information info=oper.GYSAdd(params); request.setAttribute(\, info);

request.getRequestDispatcher(\).forward(request,

response);

}

如图 4-8

代码：

private void doGYSXinXi(HttpServletRequest request,

HttpServletResponse response)throws ServletException,IOException { String gys_id = request.getParameter(\); GYSBean gysbean=new GYSBean(); gysbean = oper.GYSXinXi(gys_id);

request.setAttribute(\, gysbean);

request.getRequestDispatcher(\).forward(request,

response);

}
