list.jsp 21行，跳轉(zhuǎn)到另一個(gè)頁(yè)面，接受輸入? ??<p class="g_title fix">內(nèi)容列表 <a class="btn03" href="index.jsp">新 增</a>

和list.jsp同級(jí)創(chuàng)建index.jsp,寫一個(gè)表單? ? ?

<form action="<%=basePath %>InsertOneServlet.action" id="mainForm" method="post">

<tr>

<td width="90" align="right">指令名稱：</td>

<td>

<input name="command" type="text" class="allInput" value="${command}"/>

</td>

? ? ? ? </tr>

? ? ? ? <tr>

<td width="90" align="right">描述：</td>

<td>

<input name="description" type="text" class="allInput" value="${description}"/>

</td>

? ? ? ? </tr>

? ? ? ? <tr>

<td width="90" align="right">內(nèi)容：</td>

<td>

<input name="content" type="text" class="allInput" value="${content}"/>

</td>

</tr>

? ? ? ? <tr>

? ? ? ? ? ? <td colspan="2" width="85" align="right"><input type="submit" class="tabSub" value="確定" /></td>

? ? ? ? </tr>

創(chuàng)建InsertOneServlet，配置web.xml

//接受頁(yè)面的值

String command = req.getParameter("command");

String description = req.getParameter("description");

String content = req.getParameter("content");

MaintainService maintainService = new MaintainService();

maintainService.insertOne(command, description, content);

//向頁(yè)面跳轉(zhuǎn)

req.getRequestDispatcher("/List.action").forward(req, resp);

編寫service

public void insertOne(String command,String description,String content){

MessageDao messageDao = new MessageDao();

Message message = new Message();

message.setCommand(command);

message.setDescription(description);

message.setContent(content);

messageDao.insertOne(message);

}

編寫DAO

方法頭部? public void insertOne(Message m)

sqlSession = dBAccess.getSqlSession();

//通過(guò)sqlSession實(shí)現(xiàn)sql語(yǔ)句

sqlSession.insert("Message.insertOne",m);

System.out.println("插入方法執(zhí)行....."+"content:"+m.getContent());

sqlSession.commit();

配置Message.xml

<insert id="insertOne" parameterType="com.imooc.bean.Message" useGeneratedKeys="false">

? ? INSERT INTO MESSAGE

? ? ( ID,

? ? COMMAND,

? ? DESCRIPTION,

? ? CONTENT

? ? )

? ? VALUES

? ? ( #{id},

? ? #{command,jdbcType=VARCHAR},

? ? #{description,jdbcType=VARCHAR},

? ? #{content,jdbcType=BOOLEAN}

? ? )

? </insert>

我先從Message.xml開(kāi)始寫，寫到service不知道方法的參數(shù)該怎么寫，又從頁(yè)面開(kāi)始寫，用三個(gè)String接收輸入，在service中傳給Message對(duì)象
