数据库里的内容不能在JSP页面显示
(index2.jsp)
${not empty userList ? 'abc' : 'xxx' }
| GID | GNAME | USERID | GPRICE | GTYPE | GNUMBER |
|---|---|---|---|---|---|
| ${u.GID} | ${u.gname} | ${u.UserId} | ${u.gprice} | ${u.gtype} | ${u.gnumber} |
...........................................................
(homeServlet.java)
public class HomeServlet extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
// TODO 查询动态数据
String sql = "SELECT * FROM T_GOODS";
List> users = DBUtils.query(sql);
req.setAttribute("userList", users);
req.getRequestDispatcher("index2.jsp").forward(req, resp);
}
}
.........................
..................
然后页面就成这样了
求指导，谢谢噢
| GID | GNAME | USERID | GPRICE | GTYPE | GNUMBER |
|---|---|---|---|---|---|
| ${u.GID} | ${u.gname} | ${u.UserId} | ${u.gprice} | ${u.gtype} | ${u.gnumber} |
${not empty userList ? 'abc' : 'xxx' } 你这个判断是要把userList变成字符串吗？ 只看这个三目运算就知道userList变成了字符串！！！！
还有 你的jsp贴详细点 别人会更好理解！！
