Java 如何使用SQLite数据库中的int类型日期填充jTable

我正在使用该代码用Java（使用NetBeans）填充我的jTable。我正在使用sqlite数据库。我能够获取所有数据，除了作为长数据存储的日期数据。当我试图在jtable中显示数据时，我得到了下面提到的异常

public void fetch()
{
 try{
    String sql="select * from customer"; 
    Class.forName("org.sqlite.JDBC");
    Connection con=DriverManager.getConnection("jdbc:sqlite:D:\\Apps\\SQLite3\\FCC.db");
    Statement st=con.createStatement();
    ResultSet rs=st.executeQuery(sql); 
    jTable1.setModel(DbUtils.resultSetToTableModel(rs));
    st.close();
    con.close();        
    }                                        
    catch (HeadlessException | ClassNotFoundException | NumberFormatException | SQLException e)
  {JOptionPane.showMessageDialog(null,e);}       
}

但是日期存储为整数，我收到一条异常消息
