public class DistributieFilm {

    public static ArrayList<Film> getFilme() {

        ArrayList<Film> listaFilm = new ArrayList<Film>();
        PreparedStatement stm = null;
        ResultSet rs = null;
        Connection conn = null;
        String query = "SELECT  * FROM imdbutil.filme WHERE film_nume=?";

        try {
            conn = DbUtil.getConnection();
            stm = conn.prepareStatement(query);
            rs = stm.executeQuery();

            while (rs.next()) {

                Film lista = new Film();

                lista.setId(rs.getInt("film_id"));
                lista.setNume(rs.getString("film_nume"));

                lista.setDatalansarii(rs.getString("film_datalansarii"));

                listaFilm.add(lista);
            }

        } catch (SQLException e) {
            //
            System.out.println(e.getMessage());
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } finally {
            DbUtil.closeAll(rs, stm, conn);
        }

        return listaFilm;

我的问题是，我如何能够通过名称搜索我在数据库中获得的电影（我有5部电影，我想搜索1并显示它.ps我有一个search.jsp，我在那里添加一个文本字搜索）

由于

Answer 1

您必须将过滤条件传递给DAO类DistributieFilm;修改getFilme以接受filmNoua作为参数。

将标准设置为您的陈述

stm.setString(1, filmNoua.getName());
rs = stm.executeQuery();

在jsp中搜索一个单词
