Java 错误9952---[nio-8081-exec-1]o.h.engine.jdbc.spi.SqlExceptionHelper:ORA-00923:未在预期位置找到FROM关键字

我正在尝试从spring boot应用程序中的数据库中获取数据。我正在使用hibernate库。下面是我的实体类：

@SuppressWarnings("serial")
@Entity
@Table(name = "MU_GM_CIRCULARS")
public class GmCirculars extends ParentEntity implements Serializable {

    private BigDecimal id;
    private Date createdOn;
    private String title;
    private BigDecimal serialNo;
    private BigDecimal year;
    private BigDecimal active;
    private BigDecimal organizationId;
    private BigDecimal showOnDashboard;

    public GmCirculars() {
        super();
    }

    public GmCirculars(BigDecimal id) {
        super();
        this.id = id;
    }


    public GmCirculars(BigDecimal id, BigDecimal createdById, Date createdOn, String title, BigDecimal serialNo,
            BigDecimal year ,BigDecimal documentId, BigDecimal typeId) {
        super();
        this.id = id;
        this.createdOn = createdOn;
        this.title = title;
        this.serialNo = serialNo;
        this.year = year;

    }

    @Id
    @Column(name = "ID")
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="MU_GM_CIRCULARS_SEQ")
    @SequenceGenerator(name="MU_GM_CIRCULARS_SEQ",sequenceName="MU_GM_CIRCULARS_SEQ",allocationSize=1)
    public BigDecimal getId() {
        return id;
    }

    public void setId(BigDecimal id) {
        this.id = id;
    }

    @Column(name="created_on")
    public Date getCreatedOn() {
        return createdOn;
    }

    public void setCreatedOn(Date createdOn) {
        this.createdOn = createdOn;
    }

    @Column(name="title")
    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    @Column(name="serial_no")
    public BigDecimal getSerialNo() {
        return serialNo;
    }

    public void setSerialNo(BigDecimal serialNo) {
        this.serialNo = serialNo;
    }

    @Column(name="year")
    public BigDecimal getYear() {
        return year;
    }

    public void setYear(BigDecimal year) {
        this.year = year;
    }

    @Column(name = "org_id")
    public BigDecimal getOrganizationId() {
        return organizationId;
    }

    public void setOrganizationId(BigDecimal organizationId) {
        this.organizationId = organizationId;
    }

    @Column(name="show_on_dashboard")
    public BigDecimal getShowOnDashboard() {
        return showOnDashboard;
    }

    public void setShowOnDashboard(BigDecimal showOnDashboard) {
        this.showOnDashboard = showOnDashboard;
    }

    @Column(name = "active")
    public BigDecimal isActive() {
        return active;
    }

    public void setActive(BigDecimal active) {
        this.active = active;
    }
}

discounts = criteria.list();

下面是具有获取数据的方法的类：

@Repository
@Transactional
@SuppressWarnings("unchecked")
public class GmCircularsDaoImpl extends ParentDAO implements IGmCircularsDAO {

@Override
public List<GmCirculars> find(GmCirculars obj, boolean activeOnly, int startOffset, int maxRows) {
    Session session = null;
    List<GmCirculars> discounts = null;

    try {
        if (null != obj) {

            session= this.getSession();

            Criteria criteria = session.createCriteria(GmCirculars.class);

            if (null != obj.getId() && !BigDecimal.ZERO.equals(obj.getId())) {
                criteria.add(Restrictions.eq("id", obj.getId()));
            }

            if (StringUtil.isNotNullOrEmpty(obj.getTitle())) {
                criteria.add(Restrictions.ilike("title", obj.getTitle(), MatchMode.ANYWHERE));
            }

            if(null != obj.getOrganizationId()) {
                criteria.add(Restrictions.eq("organizationId", obj.getOrganizationId()));
            }

            if (null != obj.getSerialNo() && !BigDecimal.ZERO.equals(obj.getSerialNo())) {
                criteria.add(Restrictions.eq("serialNo", obj.getSerialNo()));
            }

            if (null != obj.getYear() && !BigDecimal.ZERO.equals(obj.getYear())) {
                criteria.add(Restrictions.eq("year", obj.getYear()));
            }


            if (activeOnly) {
                criteria.add(Restrictions.eq("active", BigDecimal.ONE));
            } else {
                criteria.add(Restrictions.or(Restrictions.ne("active", CommonConstants.DELETED_STATUS), Restrictions.isNull("active"))); //Except for deleted ones -> NVL(active,2)
            }

            criteria.setFirstResult(startOffset);
            criteria.setMaxResults(maxRows);

            criteria.addOrder(Order.desc("id"));
            criteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);

            System.out.println("criteria: "+ criteria.toString());
            discounts = criteria.list();
            System.out.println("returned list from db:"+discounts);
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        session.close();
    }
    return discounts;
}

discounts = criteria.list();

在方法

find（GmCirculars obj，boolean activeOnly，int startOffset，int maxRows）中

discounts = criteria.list();

当我运行代码时，我得到以下错误

discounts = criteria.list();

java.sql.SQLSyntaxErrorException:ORA-00942:表或视图不存在

discounts = criteria.list();
