Java-Swing内嵌网页判断网址类型_dj-native-swing

dj-native-swing
最近开发了一个项目，用Swing窗口界面内嵌网页，然后从记事本中获取到网址，页面显示网址内容，然后人工点击单选按钮判断所打开的网站是什么类型，将对应类型的网址添加到对应的记事本中，然后自动获取下一个网址，以此来判断网址的类型，下面是完成后的效果图：
1.首先，使用swing内嵌浏览器需要导入3个jar包,第3个根据电脑版本选择
dj-native-swing-swt.jar dj-native-swing.jar org.eclipse.swt.win32.win32.x86_64-4.3.jar
下载链接:https://pan.baidu.com/s/1zZ-BfP4LghyrchNc_ltT5g 密码:z0zq
2.因为网址是从记事本中获取，所以需要一个存放所有需要判断网址的记事本，另外几个记事本根据自己的要求来，用来存放判断过后不同类型的网址，当然是和单选按钮对应的，有多少个单选按钮就是多少个类型的记事本。
3.判断完后需要自动跳转记事本中的下一个网址，并将判断的网址加入到对应的记事本中，给单选按钮添加一个监听事件，选完后清空单选按钮的选中状态：clearSelection();
ra.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
int flag=JOptionPane.showConfirmDialog(null,"该网站为游戏网站？","温馨提示",JOptionPane.YES_NO_OPTION);
if(flag==JOptionPane.YES_OPTION){
i++;
if(i==x-1) {
JOptionPane.showConfirmDialog(null,"全部网址已经审核完！","温馨提示",JOptionPane.YES_NO_OPTION);
}
try {
fileInputStream = new FileInputStream(file);
inputStreamReader = new InputStreamReader(fileInputStream);
bufferedReader = new BufferedReader(inputStreamReader);
StringBuffer sb = new StringBuffer();
String text = bufferedReader.readLine();
List list = new ArrayList();
while ((text = bufferedReader.readLine()) != null) {
// 截取得到的一行数据
list.add(text);
}
a = list.get(i).toString();
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
webBrowser.navigate(a);
FileWriter fw = null;
PrintWriter pw = null;
File file2 = new File("文档\\游戏网站.txt");
try {
fw=new FileWriter(file2,true);
pw = new PrintWriter(fw);
// 把内容转换成字节数组
pw.println(a);
pw.flush();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
// 关闭输出流

pw.close();
fw.close();
} catch (Exception e) {

bg.clearSelection();
