JLabel 不像按钮，要添加鼠标事件的话 用鼠标事件监听：
    JLabel jl = new JLabel();
    		jl.addMouseListener(new MouseListener(){
    			public void mouseClicked(MouseEvent e) {
    				// 处理鼠标点击
    			}
    			public void mouseEntered(MouseEvent e) {
    				// 处理鼠标移入
    			}
    			public void mouseExited(MouseEvent e) {
    				// 处理鼠标离开
    			}
    			public void mousePressed(MouseEvent e) {
    				// 处理鼠标按下
    			}
    			public void mouseReleased(MouseEvent e) {
    				// 处理鼠标释放
    			}
    		});

JLabel label1 = new JLabel("默认保存路径:");
            label1.addMouseListener(new MouseAdapter() {
                @Override
                public void mouseClicked(MouseEvent e) {
                    JFileChooser fileChooser = new JFileChooser();
                    fileChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
                    int returnVal = fileChooser.showOpenDialog(fileChooser);
                    if (returnVal == JFileChooser.APPROVE_OPTION) {
                        String filePath = fileChooser.getSelectedFile()
                            .getAbsolutePath();//这个就是你选择的文件夹的路径
                        System.out.println("filePath = " + filePath);
                        tfSavePath.setText(filePath);
                        //TODO  日期:2020-12-04T17:17:39.372Z 目的: 设置默认保存路径
    //                    ZhihuUtils.setPrivateInfo("defSavePath",filePath);
                    }
                }
            });
