你可以參考一下：把下面的代碼內(nèi)容，跟你寫的做一下對比

一、在StudentsDAOImpl.java中實(shí)現(xiàn)添加學(xué)生的方法即可

//添加學(xué)生
?????public?boolean?addStudents(Students?s)?{
??????????//因?yàn)樘砑拥膶W(xué)生是沒有學(xué)號的，所以我們需要添加一個學(xué)號
??????????s.setSid(getNewSid());
??????????Transaction?tx?=?null;
??????????try{
??????????????Session?session?=?MyHibernateSessionFactory.getSessionFactory().getCurrentSession();
??????????????tx?=?session.beginTransaction();
??????????????session.save(s);
??????????????tx.commit();
??????????????return?true;
??????????}catch(Exception?ex){
??????????????ex.printStackTrace();
??????????????tx.commit();
??????????????return?false;
??????????}finally{
??????????????if(tx?!=?null){
???????????????????tx?=?null;
??????????????}
??????????}
?????}

二、StudentsAction類中add()方法：

//添加學(xué)生
?????public?String?add()?throws?Exception{
??????????Students?s?=?new?Students();
??????????s.setSname(request.getParameter("sname"));
??????????s.setGender(request.getParameter("gender"));
??????????SimpleDateFormat?sdf?=?new?SimpleDateFormat("yyyy-MM-dd");
??????????s.setBirthday(sdf.parse(request.getParameter("birthday")));
??????????s.setAddress(request.getParameter("address"));
??????????StudentsDAO?sdao?=?new?StudentsDAOImpl();
??????????sdao.addStudents(s);
??????????return?"add_success";
?????}

三、struts.xml

<package?name="students"?namespace="/students"?extends="default">
??????????<action?name="*_*"?class="action.{1}Action"?method="{2}">
??????????????<result?name="query_success">/students/Students_query_success.jsp</result>
??????????????<result?name="add_success">/students/Students_add_success.jsp</result>
??????????????<result?name="modify_success">/students/Students_modify.jsp</result>
??????????????<result?name="delete_success"?type="chain">Students_query</result><!--?chain表示后面鏈接一個動作,也就是服務(wù)器內(nèi)部轉(zhuǎn)發(fā)，它轉(zhuǎn)發(fā)的只能是action，而不是一個jsp頁面?-->
??????????</action>
?????</package>

四、Students_add.jsp中的form表單

<form?name="addForm"?action="<%=path%>/students/Students_add.action"?method="post">
<table?width="400"?>
??<tr>
????<td?width="30%">姓名：</td>
????<td><input?type="text"?name="sname"?/></td>
??</tr>
??<tr>
????<td>性別：</td>
????<td><input?type="radio"?name="gender"?value="男"?checked="checked"/>男<input?type="radio"?name="gender"?value="女"/>女</td>
??</tr>
??<tr>
????<td>出生日期：</td>
????<td><input?name="birthday"?type="text"?id="control_date"?size="20"
??????maxlength="10"?onclick="new?Calendar().show(this);"?readonly="readonly"?/>
????</td>
??</tr>
??<tr>
????<td>地址：</td>
????<td><input?type="text"?name="address"?/></td>
??</tr>
??<tr>
????<td?colspan="2"?align="center"><input?class="button"?type="submit"?value="添加"></td>
??</tr>
</table>
</form>
