Java jTable MouseListener 不工作

Question

我的 jTable 上的鼠标监听器有问题。这是我的代码:

 final JTable jTable1 = new JTable(tablemodel);
        JScrollPane scroll = new JScrollPane(jTable1);

        jTable1.addMouseListener(new MouseAdapter(){
            public void mouseClicked(Event e){
                System.out.println("clicekd on table");
            }
        });

但是这段代码不起作用，当我单击系统输出中的单元格数据时，不会显示。Eclipse 告诉我: new MouseAdapter(){} 类型中的 mouseClicked(Event) 方法永远不会在本地使用

编辑:这是我的功能，除了 jTable.addMouseListener

之外，一切正常

public void categoryShow() {
        // TODO Auto-generated method stub
        appListener.getCategory();
        List<Category> people = model.getPeople();

        DefaultTableModel tablemodel;

        tablemodel = new DefaultTableModel();
        final JTable jTable1 = new JTable(tablemodel);
        JScrollPane scroll = new JScrollPane(jTable1);

        jTable1.addMouseListener(new MouseAdapter(){
            @Override
            public void mouseClicked(MouseEvent e){
                System.out.println("clicekd on table");
            }
        });

        tablemodel.addColumn("ID");
        tablemodel.addColumn("Nazwa");

        for (Category person : people) {

            tablemodel.addRow(new Object[]{person.getId(),person.getName()});

        }
        JPanel controls = new JPanel(new BorderLayout(5,5));
        JPanel buttons = new JPanel(new GridLayout(0,1,4,4));

        JButton deletebutton  = new JButton("Usuń");
        JButton newrow = new JButton("Dodaj");

        print.addActionListener(new ActionListener(){

                try{
                    jTable1.print();

        });

public void mouseClicked(Event e){

应该是

@Override
public void mouseClicked(MouseEvent e) {
