我尝试将我的Department和Mandator类持久化到hsqhldb,但它给出了这个错误.

Exception Description: [class ch.printsoft.mailhouse.usermgr.entity.Mandator] uses a non-entity [class ch.printsoft.mailhouse.usermgr.entity.Department] as target entity in the relationship attribute [field departments].

这些是我尝试持久保存到我的数据库的类.我真的不知道问题是什么.

@Entity
public class Mandator {
  @Id
  @GeneratedValue
  private Integer id;
  private String mandatorId;
  @OneToMany(mappedBy = "mandator")
  private List<MandatorUser> mandatorUsers;
  @OneToMany(mappedBy = "mandator")
  private List<SLAFamilyGroup> slaFamilyGroups;
  @OneToMany(mappedBy = "mandator")
  private List<Group> groups;
  @OneToMany(mappedBy = "mandator")
  private List<Department> departments;
  @OneToMany(mappedBy = "mandator")
  private List<CostUnit> costUnits;

我创建了自定义ISO日期时间Converter:

public class IsoDateTimeConverter implements Converter, StateHolder {

    private Class type;
    private String pattern;

    private boolean transientValue = false;

    public void setType(Class type) {
        this.type = type;
    }

    public void setPattern(String pattern) {
        this.pattern = pattern;
    }

    @Override
    public Object getAsObject(FacesContext context, UIComponent component, String value) throws ConverterException {
        if (StringCheck.isNullOrEmpty(value)) {
            throw new ConverterException("value not specified");
        }

        try {
            if (IsoDate.class.equals(type)) {

                if (WebConst.ISO_DATE_NONE.equals(value)) {
                    return IsoDate.DUMMY;
                } else {
                    //TODO User spezifische TimeZone auslesen
                    return new …
