What is the alternate for deprecated Hibernate.createClob(Reader reader, int length)

Question

Seems like Hibernate.createClob(Reader reader, int length) is deprecated in version 3.6.x And it suggests to use Use LobHelper.createClob(Reader, long)

Answer 1

I have found another good alternate for this, using java javax.sql.rowset.serial.SerialClob

For example

Clob clob = new SerialClob("Some very long String.......".toCharArray());

Answer 2

It is the way of simplifying the usage by hiding the implementations. If you want to use the Clob data you need to use the below code. I have tested it in version hibernate 3.6.

session.getLobHelper().createClob("the_string");

Now coming your second point about the working of it, if you read the source code of org.hibernate.impl.SessionImpl class you will know how internally hibernate handles this.

public LobHelper getLobHelper()
/*      */   {
/* 2245 */     if (this.lobHelper == null) {
/* 2246 */       this.lobHelper = new LobHelperImpl(this, null);
/*      */     }
/* 2248 */     return this.lobHelper;
/*      */   }

Answer 3

I was using the createBlob(bytes[]) from that class. I created a new class and the following method

    public static Blob createBlob(byte[] bytes) {
       return NonContextualLobCreator.INSTANCE.wrap(NonContextualLobCreator.INSTANCE.createBlob(bytes));
    }
