从resultset填充表时更改jtable的列类型

Question

我有worker从resultset填充jtable，如下所示；

public class WorkerFillTable extends SwingWorker<DefaultTableModel, DefaultTableModel> {
        private DefaultTableModel modeltable;
        public WorkerFillTable(DefaultTableModel modeltable) {
         this.modeltable = modeltable;
        }
       @Override
     protected DefaultTableModel doInBackground() throws Exception {
            ResultSet rs;
            Statement stmt;
            String query = "select Name,ID,Status,IsActive from current_conf\n" +
            "order by Name,ID";

            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            String connectionUrl = "jdbc:sqlserver://192.168.130.100;" + "databaseName=DBST;" + "user=" + "user1" + ";" + "password=" + "userpass1" + ";"; 
            Connection con = DriverManager.getConnection(connectionUrl);
            stmt = con.createStatement();
            rs = stmt.executeQuery(query);
            ResultSetMetaData rsmd = rs.getMetaData();

            Vector<String> columnNames = new Vector<String>();
            int columnCount = rsmd.getColumnCount();

            for (int column = 0; column < columnCount; column++) {
                columnNames.addElement(rsmd.getColumnLabel(column + 1));
            } 

            Vector<Vector<Object>> data = new Vector<Vector<Object>>();

           while (rs.next()) {
                Vector<Object> vector = new Vector<Object>();
                for (int columnIndex = 1; columnIndex <= columnCount; columnIndex++) {
                vector.add(rs.getObject(columnIndex));
                }
                data.add(vector);
           }

            rs.close();
            stmt.close();
            modeltable = new DefaultTableModel(data, columnNames);
            return modeltable;
        }


      @Override
      protected void done() {
        try {
            TableModel modeltable = get();
            sorter = new TableRowSorter(modeltable);
            cTable.setRowSorter(sorter);
            cTable.setModel(modeltable);
        } catch (InterruptedException | ExecutionException ex) {
        }
      }

    }

但所有列都是字符串。DB的“Isactive”列有点只有“1”或“0”Jtable显示该列为“true”或“false”，我需要在Jtable中编辑最后一列typr来boelan。我怎么做？

JDBCADAPTER扩展了AbstractTableModel，它演示了关系数据库和Java数据类型之间的典型映射。它可以在这里看到，完整的示例可以在Samples/demo/jfc/tableexample中找到，可以在Java SE Development Kit 8u25 Demos和Samples下载中找到。在大纲上，

重写getColumnClass()。

从ResultsetMetadata获取列的数据类型。
