Hibernate 看不到实体类

当链接到 Java 中的数据库并使用getCriteriaBuilder

java.lang.IllegalArgumentException：不是实体：类 DataBase.entity.PlaceTable

这定义了一个类PlaceTable：

@Entity
@Table( name = "place" )
public class PlaceTable {

    @Id
    @Column( name = "idplace" )
    private int placeId;

    @Column( name = "idparking")
    private String parkingId;

    @Column( name = "car" )
    private boolean flagCar;

    @Column( name = "bike" )
    private boolean flagBike;

    @Column( name = "truck" )
    private boolean flagTruck;

    @Column( name = "bus" )
    private boolean flagBus;

    @Column( name = "flag" )
    private boolean empty;

    @Column( name = "idcar" )
    private String carId;

    @Column( name = "timeBegin")
    private int timeBegin;

这是对数据库的调用

    public ArrayList<PlaceTable> getWithCriteria( String field, String value ) throws HibernateException{

        CriteriaBuilder builder = session.getCriteriaBuilder();
        CriteriaQuery<PlaceTable> query = builder.createQuery(PlaceTable.class);
        Root<PlaceTable> root = query.from( PlaceTable.class );
        query.select(root).where(builder.equal( root.get( field ), value ) );
        Query<PlaceTable> q = session.createQuery(query);
        return ( ArrayList<PlaceTable> )q.getResultList();
    }

上线抛出这个异常Root<PlaceTable> root = query.from( PlaceTable.class );

使用以下方法连接到数据库：

private static final String hibernate_show_sql = "true";
private final SessionFactory sessionFactory;

private static final String DB_DIALECT  = "org.hibernate.dialect.MySQL5Dialect";
private static final String DB_DRIVER   = "com.mysql.jdbc.Driver";
private static final String DB_URL      = "jdbc:mysql://localhost:3306/mydb?useSSL=false";
private static final String DB_USERNAME = "root";
private static final String DB_PASSWORD = "geo";


public DBService() {
    Configuration configuration = getMySqlConfiguration();
    sessionFactory = createSessionFactory(configuration);
}

@SuppressWarnings("UnusedDeclaration")
private Configuration getMySqlConfiguration() {
    Configuration configuration = new Configuration();

    configuration.addAnnotatedClass(ParkingTable.class);
    configuration.addAnnotatedClass(CarTable.class);

    configuration.setProperty("hibernate.dialect",                 DB_DIALECT );
    configuration.setProperty("hibernate.connection.driver_class", DB_DRIVER );
    configuration.setProperty("hibernate.connection.url",          DB_URL );
    configuration.setProperty("hibernate.connection.username",     DB_USERNAME );
    configuration.setProperty("hibernate.connection.password",     DB_PASSWORD );
    configuration.setProperty("hibernate.show_sql",                hibernate_show_sql );
    return configuration;
}
