现在大多数smtp服务器都需要身份认证，若用javamail写一个邮件收发客户端，怎么来实现这种功能呢？下面是一个简单的列子，模拟foxmail对认证功能的实现。
package jmail;
import javax.mail.*;
import java.util.*;
import java.sql.*;
import javax.swing.*;
import java.awt.*;
public class MailAuthenticator extends Authenticator{
String authenName; //用户名
String authenPass; //密码
public MailAuthenticator(String authenName,String authenPass) {
super();
this.authenName=authenName;
this.authenPass=authenPass;
}
public PasswordAuthentication getPasswordAuthentication(){ /*若服务器需要身份认证，Sission会自动调用这个方法
String temp=null;
if(authenPass.equals("")||authenPass==null){ /*若密码为空*/
Option op=new Option(null,"身份验证",true); /*弹出要求用户输入密码的对话框，Option是自定义的JDialog，包含一个密码域*/
temp=op.showDialog(); /*Option的返回输入的密码*/
authenPass=temp;
}
return new PasswordAuthentication(authenName,authenPass);
}
}
/* 下面是Option 类，jbuilder里写的，无须解释*/
package jmail;
import java.awt.*;
import javax.swing.*;
import com.borland.jbcl.layout.*;
import java.awt.event.*;
public class Option extends JDialog {
JPanel panel1 = new JPanel();
JLabel jLabel1 = new JLabel();
XYLayout xYLayout1 = new XYLayout();
JButton jButton1 = new JButton();
JButton jButton2 = new JButton();
JPasswordField jPasswordField1 = new JPasswordField();
JLabel jLabel2 = new JLabel();
JLabel jLabel3 = new JLabel();
Icon forget=new ImageIcon(".\images\forget.gif");
boolean ok=false;
JLabel jLabel4 = new JLabel();
JLabel jLabel5 = new JLabel();
public Option(Frame frame, String title, boolean modal) {
super(frame, title, modal);
try {
jbInit();
pack();
}
catch(Exception ex) {
ex.printStackTrace();
}
}
public Option() {
this(null, "", false);
}
private void jbInit() throws Exception {
panel1.setLayout(xYLayout1);
jLabel1.setFont(new java.awt.Font("Dialog", 0, 12));
jLabel1.setText("密码:");
jButton1.setFont(new java.awt.Font("Dialog", 0, 12));
jButton1.setDoubleBuffered(false);
jButton1.setText("确定");
jButton1.addActionListener(new Option_jButton1_actionAdapter(this));
jButton2.setFont(new java.awt.Font("Dialog", 0, 12));
jButton2.setText("取消");
jButton2.addActionListener(new Option_jButton2_actionAdapter(this));
jLabel2.setFont(new java.awt.Font("Dialog", 0, 12));
jLabel2.setHorizontalTextPosition(SwingConstants.TRAILING);
jLabel2.setIcon(forget);
jLabel2.setText("");
jLabel3.setFont(new java.awt.Font("Dialog", 0, 12));
jLabel3.setText("服务器需要身份认证, 请输入密码");
panel1.setToolTipText("");
jLabel4.setText(" ");
jLabel5.setText(" ");
getContentPane().add(panel1, BorderLayout.CENTER);
panel1.add(jLabel4, new XYConstraints(189, 61, -1, -1));
panel1.add(jLabel2, new XYConstraints(15, 1, 67, 19));
panel1.add(jLabel3, new XYConstraints(15, 22, -1, -1));
panel1.add(jPasswordField1, new XYConstraints(48, 46, 140, -1)); |
