字数限制 ，有些代码没弄

public class KeFu implements ActionListener{
public Box vbox52;
JButton button51;
JTextField jtf;
public static JTextArea jta;

public void kefu() {

JLabel jlb51 = new JLabel("欢迎您来到国航订票系统，如您遇到问题请在下面提问！");
System.out.println("服务器已打开");
jta = new JTextArea(15, 40);
jta.setEditable(true);

JScrollPane jsp51 = new JScrollPane(jta);

JLabel jlb52 = new JLabel("请输入：");

jtf = new JTextField(15);
button51 = new JButton("发送");

Box hbox51 = Box.createHorizontalBox();
hbox51.add(jlb52);
hbox51.add(jtf);
hbox51.add(button51);

vbox52 = Box.createVerticalBox();
vbox52.add(Box.createVerticalStrut(10));
vbox52.add(jlb51);
vbox52.add(Box.createVerticalStrut(10));
vbox52.add(jsp51);
vbox52.add(Box.createVerticalStrut(20));
vbox52.add(hbox51);
button51.addActionListener(this);
}

public void actionPerformed(ActionEvent e) {
if (e.getSource().equals(button51)) {
// 和服务器咨询
String s = jtf.getText();
jtf.setText("");
System.out.println(s);
Client1 ct=new Client1();
try {

ct.out.writeUTF(s);//向服务器端输入咨询

jta.append(("\n" +"您："+ s));

} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
}
}

Answer 1

你这个是循环读取 ， 你每一次的sock读取后没有关闭 引起的。
