Update vlastnosti typu UserType v Hibernate 2.1

[Vlastimil Vávrů]

Zdravím konferenci,
chci se zeptat zda někdo z vás již pracovat s UserType v Hiberenatu.  
Používám jej pro status uživatele. Viz:

package cz.venturia.imagebank;

import java.io.Serializable;
import java.util.HashMap;
import java.util.Map;

public class UserStatus implements Serializable {
        private static final long serialVersionUID = 11 * Long.MIN_VALUE;

        private String name;

        public static final UserStatus ENABLED = new UserStatus("ENABLED");
        public static final UserStatus DISABLED = new UserStatus("DISABLED");
	public static final UserStatus NOT_APPROVED = new  
UserStatus("NOT_APPROVED");
        private static final Map INSTANCES = new HashMap();

        static {
                INSTANCES.put(ENABLED.toString(), ENABLED);
                INSTANCES.put(DISABLED.toString(), DISABLED);
                INSTANCES.put(NOT_APPROVED.toString(), NOT_APPROVED);
        }

        private UserStatus(String name) {
                this.name = name;
        }

        public String toString() {
                return name;
        }

        private Object readResolve() {
                return getInstance(name);
        }

        public static UserStatus getInstance(String name) {
                return (UserStatus) INSTANCES.get(name);
        }
}

UserStatusType trida vypada takto:

package cz.venturia.imagebank.hibernate;

import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Types;

import net.sf.hibernate.HibernateException;
import net.sf.hibernate.UserType;
import cz.venturia.imagebank.UserStatus;

public class UserStatusUserType implements UserType {

        private static final int[] SQL_TYPES = { Types.VARCHAR };

        public Object deepCopy(Object value) throws HibernateException {
                return value;
        }

        public boolean equals(Object x, Object y) throws HibernateException {
                return x == y;
        }

        public boolean isMutable() {
                return true;
        }

	public Object nullSafeGet(ResultSet rs, String[] names, Object owner)  
throws HibernateException, SQLException {
                String name = rs.getString(names[0]);
                return rs.wasNull() ? null : UserStatus.getInstance(name);
        }

	public void nullSafeSet(PreparedStatement st, Object value, int index)  
throws HibernateException, SQLException {
                if (value == null) {
                        st.setNull(index, Types.VARCHAR);
                } else {
                        st.setString(index, value.toString());
                }
        }

        public Class returnedClass() {
                return UserStatus.class;
        }

        public int[] sqlTypes() {
                return SQL_TYPES;
        }
}

Zkusil jsem dal breakpointy do vsech metod ve tride UserTypeStatus - pri  
startu aplikace se zavola pouze sqlTypes a returnedClass.

Pri cteni ani ukladani se jiz nevola zadna metoda.

Zvlastni je, ze pri vytvareni uzivatele (registraci) se status nastavi (na  
NOT_APPROVED)


Dík za rady.
