经过俩个星期的奋斗,易买网项目完工。在之前,实现图片的上传,走过许多弯路,原来是好多基础的知识忘记了,没把smartupload文件包添加组件jar包至WEB-INF/lib包中,在此特别重视,做下文件的上传。
第一步:创建商品实体类:
package entity;public class easybuy_PRoductn { private int ep_id ;//编号 private String ep_name ;//名字 private String ep_description ;//描述 private int ep_price;//价格 private int ep_stock ;//库存 private int epc_id ;//父类id private int epc_child_id ;//二级id private String ep_file_name ;//文件名 private int tiaoma ;//条码号 public int getEp_id() { return ep_id; } public void setEp_id(int epId) { ep_id = epId; } public String getEp_name() { return ep_name; } public void setEp_name(String epName) { ep_name = epName; } public String getEp_description() { return ep_description; } public void setEp_description(String epDescription) { ep_description = epDescription; } public int getEp_price() { return ep_price; } public void setEp_price(int epPrice) { ep_price = epPrice; } public int getEp_stock() { return ep_stock; } public void setEp_stock(int epStock) { ep_stock = epStock; } public int getEpc_id() { return epc_id; } public void setEpc_id(int epcId) { epc_id = epcId; } public int getEpc_child_id() { return epc_child_id; } public void setEpc_child_id(int epcChildId) { epc_child_id = epcChildId; } public String getEp_file_name() { return ep_file_name; } public void setEp_file_name(String epFileName) { ep_file_name = epFileName; } public int getTiaoma() { return tiaoma; } public void setTiaoma(int tiaoma) { this.tiaoma = tiaoma; }}
第二步:编写sql:
//添加商品public int Produt(String epName, String epDescription, int epPrice, int epStock, int epcId, String epFileName,String ep_name_tiaoma) { //创建数据库的链接 con=this.getConnection(); //创建int值确认是否插入成功 int i=0; //创建sql语句 String sql="insert into easybuy_productn values(easybuy_productn_seq.nextval,?,?,?,?,?,'',?,?)"; try { //写入sql st=con.prepareStatement(sql); st.setString(1, epName); st.setString(2, epDescription); st.setInt(3, epPrice); st.setInt(4, epStock); st.setInt(5, epcId); st.setString(6, epFileName); st.setString(7, ep_name_tiaoma); //开始执行sql i=st.executeUpdate(); //开始判断 if(i>0){ i=1; }else{ i=0; } //释放链接 this.ShiFang(rs, st, con); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } return i;}
添加商品jsp页面
<h2>添加商品</h2> <div class="manage"> <form action="manage/MyJsp.jsp" method="post" enctype="multipart/form-data"> <table class="form"> <tr> <td class="field">描述描述:</td> <td><input type="text" class="text" name="productName" id="productscript" value="铁三角 Audio-Technica ATH-EQ300M-SV 银色 挂耳式耳机" /></td> </tr> <tr> <td class="field">所属分类:</td> <td> <select name="parentId"> <c:forEach var="news" items="${requestScope.flist1}" > <option value="1">${news.epc_name}</option> <c:forEach var="ck" items="${flist}" > <c:if test="${ck.epc_parent_id == news.epc_id}"> <option value="3">${ck.epc_name}</option> </c:if> </c:forEach> </c:forEach> </select> </td> <tr> <td class="field">头像:</td> <td><input type="file" name="fileg" id="imgOne" onchange="preImg(this.id,'imgPre');"/></td> </tr> <tr> <td>头像预览:</td> <td><img id="imgPre" src="" style="width:150px;height:150px;display:block;"/></td> </tr> <tr> <td class="field">商品价格:</td> <td><input type="text" class="text tiny" name="productPrice" id="productPrice" /> 元</td> </tr> <tr> <td class="field">名称:</td> <td><input type="text" class="text" name="productName2" id="productName" /></td> </tr> <tr> <td class="field">库存:</td> <td><input type="text" class="text tiny" name="productName3" id="producstock"/></td> </tr> <tr> <td class="field">条号码:</td> <td><input type="text" class="text tiny" name="productName4" id="producstock"/></td> </tr> <tr> <td></td> <td><label class="ui-blue"><input type="submit" name="submit" value="添加" /></label></td> </tr> </table> </form>
