我只得到结果？？？？？？当我使用 java Servlet 在 Eclipse 中读取数据库时

结果是英语

福特福克斯电动汽车达到 100 英里/加仑以上 福特开始生产福克斯电动汽车，声称它将在效率方面超越电动汽车竞争对手，同时它的目标是丰田普锐斯，其 C-Max 混合动力和插电式混合动力预计将在下半年推出明年的。

工作正常。

但作为阿拉伯语不起作用'D39H/J）//这应该是阿拉伯语'DEEDC）

尝试

                String header=rs.getString("headline").getBytes("utf-8");
                hyper=rs.getString("link").getBytes("utf-8");
                String info=rs.getString("info").getBytes("utf-8");

  • 经过大量搜索后，我发现了一个非常好的解决方法，即将阿拉伯语的列转换为 varbinary，然后将其作为字节放入您的 java 项目中，然后创建一个新字符串，该字符串将字节数组作为构造函数参数，这将使用阿拉伯编码“Windows-1256”来映射阿拉伯字符的正确值

    • 这是代码示例

SQL 选择语句：

select cast([column_name] as varbinary(max)) from [table_name] where [condition]

爪哇代码：

            Statement stat = con.createStatement();
            ResultSet rs = stat.executeQuery("select cast([column_name] as varbinary(max)) from [table_name] where [condition]");
            while (rs.next()) {
                byte[] tmp = rs.getBytes("column_name");
                String cloumn_value = new String(tmp, "Windows-1256");
                //cloumn_value arabic value
            }
