Hibernate不会保存UserType

Question

我有一个对象(人)，我试图使用Hibernate保存到数据库中。Person有一个Hibernate UserType对象。我无法将人保存到数据库，我认为问题是UserType。

我记录了Sql以查看发生了什么，并且注意到记录器跳过了UserType参数。这是因为没有将值发送到数据库吗？

insert into person_detail (code, person_type, person_id, name) values (?, ?, ?, ?)

22.01.15 16:16:41 TRACE [main] >>    [org.hibernate.type.descriptor.sql.BasicBinder]  binding parameter [1] as [VARCHAR] - J1
22.01.15 16:16:41 TRACE [main] >>    [org.hibernate.type.descriptor.sql.BasicBinder]  binding parameter [3] as [NUMERIC] - 99
22.01.15 16:16:41 TRACE [main] >>    [org.hibernate.type.descriptor.sql.BasicBinder]  binding parameter [4] as [NUMERIC] - Joe

private Class enumClass;

  public void setParameterValues(Properties params) {

    this.enumClass = classForProp("enumClassName", params);
  }

  public final String toString(Object value) throws HibernateException {
    if (value == null) {
      return null;
    }
    if (value instanceof Enum) {
      final Enum eValue = (Enum) value;
      return eValue.name();
    }
    else {
      final String valueClass = value.getClass().getName();
      throw new IllegalArgumentException("Error trying to convert value to String. Expected instance of Enum, but got " + valueClass);
    }
  }

  @SuppressWarnings("unchecked")
  public final Object fromString(String cached) throws HibernateException {
    if (cached == null) {
      return null;
    }

    try {
      return Enum.valueOf(enumClass, cached);
    }
    catch (IllegalArgumentException iae) {
      throw new SerializationException(enumClass.getName() + " value in database is invalid: " + cached, iae);
    }
  }
}

原来我的记录一直在存钱。单元测试在保存后立即删除我的记录，所以我假定它没有被保存。我将测试包装在一个事务中，以便在它运行后回滚。我真傻。
