convert String to Clob and vice versa in Hibernate

Question

Suppose that I have a Class:

class EventTransaction {
    .....
    private Clob dataXML;

    public Clob getDataXML() {
       return dataXML;
    }

    p         


        

Answer 1

Here is code I made a long time ago to convert a Clob to a String. It's meant to be used in a utility class.

    public static String convertClobToString(Clob clob) throws IOException, SQLException {
            Reader reader = clob.getCharacterStream();
            int c = -1;
            StringBuilder sb = new StringBuilder();
            while((c = reader.read()) != -1) {
                 sb.append(((char)c));
            }

            return sb.toString();
     }

And if I am not mistaken, to create a Clob you would do something like this

     Clob myClobFile = new SerialClob("my string".toCharArray());
