我有以下代码:
@Override
public Iterator retrieve() throws SQLException {
List<PasalBean> pasalObject = new ArrayList<PasalBean>();
try {
Class.forName(dbDriver);
con = DriverManager.getConnection(url);
ps = con.createStatement();
rs = ps.executeQuery("select * from T_PASAL WHERE ID_PASAL = '" + id_pasal + "' ORDER BY ID_PASAL");
while (rs.next()) {
pasalObject.add(new PasalBean(rs.getInt(1), rs.getString(2), rs.getString(3), rs.getString(4)));
}
}catch (Exception e) {
System.out.println("Error Data : " + e.getMessage());
}
return (Iterator) pasalObject;
}
如何在JSP中显示它?
答案 0 :(得分:1)
首先,此代码将失败。您无法将List
转换为Iterator
。让它返回List
。
然后,为了在servlet中显示它,你需要的是:
request.setAttribute("list", retrieve());
request.getRequestDispatcher("/path/to/jsp").forward();
然后在JSP中:
<c:forEach items="${list}" var="item">
${item.somePropertyOfTheBean}
</c:forEach>
最好将retrieve()
方法放在单独的数据访问类(DAO)中,而不是直接放在servlet中。
