我能够检索数据并在控制台上打印但我无法在jsp中打印数据是dao中的代码
while(rs.next())
{
System.out.println(rs.getString(1) +" " + rs.getString(2)+ " "+rs.getString(3) +" " + rs.getString(4)+"<br>");
SearchProjVO projVO = new SearchProjVO();
projVO.setProjid(rs.getString(1));
projVO.setProjname(rs.getString(2));
projVO.setCost(rs.getString(3));
projVO.setManager(rs.getString(4));
ar.add(projVO);
}
在jsp我以下列格式调用这些变量是正确的
<td class="td-highlighted-2">
<div align="left"><a href="UpdateProject.html">${resultList.projId}</a></div>
</td>
<td class="td-highlighted-2">
<div align="left">${resultList.projName}</div>
</td>
<td class="td-highlighted-2">
<div align="left">${resultList.cost}</div>
</td>
<td class="td-highlighted-2">
<div align="left">${resultList.manager}</div>
</td>
</tr>
</c:forEach>
答案 0 :(得分:1)
看起来您正在遍历结果列表。假设您在列表中有一个可从您的页面访问的SearchProjVO对象列表,那么这样的东西就可以了:
<c:forEach var="result" items="${resultList}">
<tr>
<td class="td-highlighted-2">
<div align="left"><a href="UpdateProject.html">${result.projId}</a></div>
</td>
<td class="td-highlighted-2">
<div align="left">${result.projname}</div>
</td>
<td class="td-highlighted-2">
<div align="left">${result.cost}</div>
</td>
<td class="td-highlighted-2">
<div align="left">${result.manager}</div>
</td>
</tr>
</c:forEach>
