Answer 1

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");

Answer 2

经过大量搜索后，我发现了一个非常好的解决方法，即将阿拉伯语中的列转换为varbinary，然后将其作为字节在java项目中获取，然后创建一个接受字节数组的新字符串作为构造函数参数，将使用阿拉伯语编码＆＃34; Windows-1256＆＃34;映射阿拉伯字符的正确值
- 这是代码示例

SQL select语句：

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

java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
            }
