Hi, I struggle with the i18n setup in my application. I have now tried to follow this recipe: http://www.theserverside.com/news/1377072/Internationalized-Data-in-Hibernate
And it works as long as I don't use the second level cache. When I do use it the first value is cached and return even if I later change the language. (Through the disassemble and assemble methods). I really hope someone can help me with this one, cause I need to cache the CarType entity, just not the userType-part. (The I18nLocaleHolder operates on an in-memory map)
Here is part of the entity class:
Code:
@Cache(usage = CacheConcurrencyStrategy.READ_ONLY)
@Immutable
@Table(name = "CAR_TYPE")
public class CarType implements Serializable {
@Id
private Long id;
@Type(type = "LocalizedLabelUserType")
private String description;
...
And here is the userType:
Code:
public class LocalizedLabelUserType implements UserType {
@Override
public int[] sqlTypes() {
return new int[] { Types.INTEGER };
}
@Override
public Class<String> returnedClass() {
return String.class;
}
@Override
public boolean equals(Object x, Object y) throws HibernateException {
return x == y;
}
@Override
public int hashCode(Object x) throws HibernateException {
return x == null ? 0 : x.hashCode();
}
@Override
public Object nullSafeGet(ResultSet rs, String[] names, SessionImplementor session, Object owner) throws HibernateException,
SQLException {
Long labelId = (Long) LongType.INSTANCE.nullSafeGet(rs, names, session, owner);
return I18nLocaleHolder.getDescription(labelId, LocaleContextHolder.getLocale().getLanguage());
}
@Override
public void nullSafeSet(PreparedStatement st, Object value, int index, SessionImplementor session) throws HibernateException,
SQLException {
Long code = I18nLocaleHolder.getCode((String) value, LocaleContextHolder.getLocale().getLanguage());
LongType.INSTANCE.nullSafeSet(st, code, index, session);
}
@Override
public Object deepCopy(Object value) throws HibernateException {
return value;
}
@Override
public boolean isMutable() {
return false;
}
@Override
public Serializable disassemble(Object value) throws HibernateException {
return (Serializable) value;
}
@Override
public Object assemble(Serializable cached, Object owner) throws HibernateException {
return cached;
}
@Override
public Object replace(Object original, Object target, Object owner) throws HibernateException {
return original;
}
}
