Java中Servlet中應用

web層：

<form action =”http://localhost:8080/servlet/UInfoServlet”  method=”post”>

<input name =“btnSave” type=”submit” value=”保存”>

</form>

 

在Servlet中運行：

protected void doGet(HttpServletRequest request, HttpServletResponse response)

            throws ServletException, IOException {

    LiNingEntity.ApplicationDataFlowDiagram adf=null;

        com.bll.DataApplication.DataManagerApproveMgr da=new DataManagerApproveMgr();

//1.讀取屬性值

    try{

        request.setAttribute(“”,adf.getAgentCell());//第一個參數書捕捉前臺的文本名，第二個參數得到實體類該屬性的值（從數據庫中獲取）。

} catch (SQLException e){

                e.printStackTrace();

}

}

//2.寫入屬性值

try{

        asf.setAuditComents(request.getParameter(“ ”));//參數數據庫字段名

} catch (SQLException e){

                e.printStackTrace();

}

}

 

request.getResquestDispatcher(“Uinfo.jsp”).forward(request,response);//第一個參數是返回到頁面地址

 

//因爲前邊用的是：post方法

protected void doPost(HttpServletRequest request, HttpServletResponse response)         throws ServletException, IOException {

    this.doGet(request,response);

}
