第一步：在edu.fzu.openfund.domain包下新建类Client。

public class Client {    private String IDCardNO; // 客户身份证号    private String clientName; // 客户姓名    private String clientSex; // 客户性别    private String clientPhone; // 客户联系电话    private String clientAddress; // 客户地址    private String clientEmail; // 客户电邮    private String clientHobby; // 客户爱好    private Date clientCreateDate; // 客户创建时间    public String getIDCardNO()    {        return IDCardNO;    }    public void setIDCardNO(String cardNO)    {        IDCardNO = cardNO;    }    public String getClientName()    {        return clientName;    }    public void setClientName(String clientName)    {        this.clientName = clientName;    }    public String getClientSex()    {        return clientSex;    }    public void setClientSex(String clientSex)    {        this.clientSex = clientSex;    }    public String getClientPhone()    {        return clientPhone;    }    public void setClientPhone(String clientPhone)    {        this.clientPhone = clientPhone;    }    public String getClientAddress()    {        return clientAddress;    }    public void setClientAddress(String clientAddress)    {        this.clientAddress = clientAddress;    }    public String getClientEmail()    {        return clientEmail;    }    public void setClientEmail(String clientEmail)    {        this.clientEmail = clientEmail;    }    public String getClientHobby()    {        return clientHobby;    }    public void setClientHobby(String clientHobby)    {        this.clientHobby = clientHobby;    }    public Date getClientCreateDate()    {        return clientCreateDate;    }    public void setClientCreateDate(Date clientCreateDate)    {        this.clientCreateDate = clientCreateDate;    }}

第二步：在edu.fzu.openfund.controller包下新建Servlet，类名ClientMgrServlet。点击Next，设置Mapping URL为/client。

第三步：编写doPost()和doGet()方法的代码。

public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {request.setCharacterEncoding("utf-8");int mid = Integer.parseInt(request.getParameter("mid"));// get inputClient.jspif (mid == 0) {request.getRequestDispatcher("/Client/inputClient.jsp").forward(request, response);}else if (mid == 1) {Client client = new Client();client.setIDCardNO(request.getParameter("idcard_no"));client.setClientName(request.getParameter("client_name"));if(request.getParameter("client_sex")!=null)client.setClientSex("client_sex");if(request.getParameter("client_phone")!=null)client.setClientPhone("client_phone");if(request.getParameter("client_address")!=null)client.setClientAddress("client_address");if(request.getParameter("client_email")!=null)client.setClientEmail("client_email");if(request.getParameter("client_hobby")!=null)client.setClientHobby("client_hobby");client.setClientCreateDate(new Date());request.getRequestDispatcher("/Client/insertClientRes.jsp?rid=0").forward(request, response);}}

第四步：修改web.xml文档。

  <servlet-mapping>    <servlet-name>ClientMgrServlet</servlet-name>    <url-pattern>/clientMgr</url-pattern>  </servlet-mapping>

第五步：在WebRoot下建立目录Client，在该目录新建inputClient.jsp。

<%@ page language="java" import="java.util.*,edu.fzu.openfund.domain.*"pageEncoding="utf-8"%><%String path = request.getContextPath();String basePath = request.getScheme() + "://"+ request.getServerName() + ":" + request.getServerPort()+ path + "/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head><base href="<%=basePath%>"><title>新增客户</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0"><meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><link rel="stylesheet" type="text/css" href="css/bootstrap.css"></head><body><form action="clientMgr?mid=1" method="post" class="form-horizontal"><div class="control-group"><legend><span class="controls"> 新增客户 </span></legend></div><div class="control-group"><label class="control-label" for="idcardno">客户身份证号：</label><div class="controls"><input type="text" name="idcard_no" maxlength="18" id="idcardno" /></div></div><div class="control-group"><label class="control-label" for="clientname">客户姓名：</label><div class="controls"><input type="text" name="client_name" maxlength="30"id="clientname" /></div></div><div class="control-group"><label class="control-label" for="clientsex">客户性别：</label><div class="controls"><select name="client_sex" id="clientsex" class="input-medium"><option value="">==请选择==</option><option value="M">男</option><option value="F">女</option></select></div></div><div class="control-group"><label class="control-label" for="clientphone">客户手机号码:</label><div class="controls"><input type="text" name="client_phone" maxlength="20"id="clientphone" /></div></div><div class="control-group"><label class="control-label" for="clientaddress">客户住宅地址:</label><div class="controls"><input type="text" name="client_address" maxlength="20"id="clientaddress" /></div></div><div class="control-group"><label class="control-label" for="clientemail">客户电子邮箱:</label><div class="controls"><input type="text" name="client_email" maxlength="50"id="clientemail" /></div></div><div class="control-group"><label class="control-label" for="clienthobby">客户兴趣爱好:</label><div class="controls"><input type="text" name="client_hobby" maxlength="50"id="clienthobby" /></div></div><div id="submiter" class="control-group"><div class="controls"><input type="submit" value=" 添 加 " class="btn btn-primary" /></div></div></form></body></html>

第六步：在WebRoot下建立目录Client，在该目录新建inputClientRes.jsp。

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head><title>新增客户</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0"><meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><!--<link rel="stylesheet" type="text/css" href="styles.css">--><link rel="stylesheet" type="text/css" href="css/bootstrap.css"></head><body><%           request.setCharacterEncoding("UTF-8");    String rid = request.getParameter("rid");    if (rid.equals("0")){%>    <script>alert("成功添加！");window.location.assign("clientMgr?mid=0");</script><%            }    else{    %>                <script>    alert("添加失败！未知原因，请通知管理员");history.go(-1);</script><%    }    %></body></html>
