在JTable中显示来自mysql的数据

[英]Display data from mysql in JTable

问题描述

如何将数据从mysql表插入到JTable中？ 而且我希望能够对mysql表进行UPDATE，DELETE和ADD操作。 这应该是我的餐厅应用程序，我希望用户在该JTable中看到餐厅库存，然后单击“表格”按钮，它会打开一个新框架，用户可以在其中添加或删除库存中的产品或从中兑现产品。 一旦在表使用中添加或删除了产品，mysql表自动更新就很酷了。

    DbConnection conn = new DbConnection();
    Connection connection = conn.getConnection();
    Statement st;
    Vector data = new Vector();
    try {
        st = connection.createStatement();
        ResultSet res = st.executeQuery("SELECT col_name FROM table_name");
        ResultSetMetaData metaData = res.getMetaData();
        int columns = metaData.getColumnCount();
        while (res.next()) {
           Vector row = new Vector(columns);
           for (int i = 1; i <= columns; i++) {
            row.addElement(res.getObject(i));
           }
           data.addElement(row);
        }
    } catch (SQLException e) {
        e.printStackTrace();
    }
    Vector columnNames = new Vector();
    columnNames.addElement("col_1");
    columnNames.addElement("col_name_n");
    table = new JTable(data,columnNames);

您可以使用上面的代码。 步骤：1.您与数据库建立连接2.您执行查询3.将数据库中的数据存储到向量中4.使用存储在向量中的数据创建Jtable
