Stream in Java is converted to object serializable

I. PO entity class

public class buispo{      /**        * Business Data */        private Bolb buisdata;       Public Blob Getbusidata () {return this.busidata;       }       public void Setbusidata (Blob busidata) {this.busidata = Busidata;
      } }

Two. Get this Blob object from the database

Busipo Busipo =Busidao.finduniquewithproperty (parammap); InputStream is=NULL; Try {       if(Istapprbusidatapo! =NULL) { is=busipo.getbusidata (). Getbinarystream ();//Get binary stream from blob (large object)}Else {                    return NULL; }     } Catch(SQLException e) {logger.error ("Error getting business data", E); Throw Newshineexception (e); }    return(Serializable)   Serializationutils.deserialize (IS); Using the Serializationutils class as the serialization tool class, reverse the input stream to the serial number

    Serializationutils The class is a serialization tool class and a tool under the Lang Package, primarily for serialization operations, while providing an object cloning interface

Three. converting serialization to Object

return (Object) Tempbusidataenti.querybusidatabyinstanceid (instanceId);
