Decode datatTable aoData.push parmater in controller

Am using Jquery Datatable verion 1.9.4 and spring MVC.I want to pass encoded parameters to controller using aoData.push method. I have used :

aoData.push({"name":"Id", "value":encodeURIComponent(Id)})

but in controller this not automatically decoding. Is there any way to decode the dataTable parameters in controller like filters?

Any help or guidance would be appreciated
