I fixed this behavior with a simple UserType. Just annotate
| import org.hibernate.annotations.Type;
| ...
| @Column(name = "XYZ")
| @Type(type = "usertype.TrimmedStringType")
| private String xyz;
|
The TrimmedStringType source is like this:
| package usertype;
|
| import java.io.Serializable;
| import java.sql.PreparedStatement;
| import java.sql.ResultSet;
| import java.sql.SQLException;
| import java.sql.Types;
|
| import org.hibernate.HibernateException;
| import org.hibernate.usertype.UserType;
|
|
| public class TrimmedStringType implements UserType {
|
| private static final int[] SQL_TYPES = { Types.CHAR };
|
| public int[] sqlTypes() {
| return SQL_TYPES;
| }
|
| public Class returnedClass() {
| return String.class;
| }
|
| public Object assemble(Serializable cached, Object owner) throws
HibernateException {
| return cached;
| }
|
| public Object deepCopy(Object obj) throws HibernateException {
| if (obj == null) {
| return null;
| }
| return new String((String) obj);
| }
|
| public Serializable disassemble(Object value) throws HibernateException
{
| return (Serializable) value;
| }
|
| public boolean equals(Object x, Object y) throws HibernateException {
| return (x == y) || (x != null && y != null && (x.equals(y)));
| }
|
| public int hashCode(Object x) throws HibernateException {
| return x.hashCode();
| }
|
| public boolean isMutable() {
| return false;
| }
|
| public Object nullSafeGet(ResultSet rs, String[] names, Object obj)
throws HibernateException, SQLException {
| String val = rs.getString(names[0]);
| return val != null ? val.trim() : null;
| }
|
| public void nullSafeSet(PreparedStatement pstmt, Object obj, int i)
throws HibernateException, SQLException {
| pstmt.setString(i, (String)obj);
| }
|
| public Object replace(Object original, Object target, Object owner)
throws HibernateException {
| return original;
| }
| }
|
I hope this helps.
