哪位帮我解决一下关于Hibernate递归映射的现象

@Entity
@Table(name = "itsc_domain_info")
public class ItscDomainInfo implements Serializable {

    private static final long serialVersionUID = 1L;

    public final static String PROPERTY_ORG_NAME = "domainName";

    public final static String PROPERTY_PARENT_ORG = "parentDomain";
    
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Basic(optional = false)
    @Column(name = "domain_id")
    private Integer domainId;

    @Column(name = "domain_name")
    private String domainName;

    @Column(name = "domain_type")
    private int domainType;

    @Column(name = "domain_desc")
    private String domainDesc;

    @ManyToOne
    @JoinColumn(name = "parent_domain", referencedColumnName = "domain_id")
    private ItscDomainInfo parentDomain;

    @OneToMany(mappedBy = "parentDomain",  cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    private List<ItscDomainInfo> childDomains;

@Entity
@Table(name = "itsc_user_info")
public class ItscUserInfo implements Serializable {

    private static final long serialVersionUID = 1L;

    public static final String PROPERTY_USER_NAME = "userName";

    public static final String PROPERTY_USER_ROLEID = "roleInfo.roleId";

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Basic(optional = false)
    @Column(name = "user_id")
    private Integer userId;

    @Column(name = "user_name", updatable = false)
    private String userName;

    @Column(name = "user_pwd")
    private String userPwd;

    @Column(name = "user_telephone")
    private String userTelephone;

    @Column(name = "user_position")
    private String userPosition;

    @OneToOne
    @JoinColumn(name = "role_id", referencedColumnName = "role_id")
    private ItscRoleInfo roleInfo;

    @ManyToOne
    @JoinColumn(name = "user_domain", referencedColumnName = "domain_id")
    private ItscDomainInfo domainInfo;
......
}

 DetachedCriteria detachedCriteria = DetachedCriteria.forClass(this.entityClass);
            // log.debug("this.objectClass:" + this.objectClass);
            detachedCriteria = detachedCriteria.add(Expression.eq(keyName, key));
            List<T> list = this.getHibernateTemplate().findByCriteria(
                    detachedCriteria);
