以一个web项目为例,代码是可以移植的
首先要导入mail.jar包,然后创建自己的类
1:HTMLSender类
1 package com.txq.mail; 2 3 import java.util.Properties; 4 5 import javax.mail.Message; 6 import javax.mail.MessagingException; 7 import javax.mail.NoSuchProviderException; 8 import javax.mail.Session; 9 import javax.mail.Transport; 10 import javax.mail.internet.AddressException; 11 import javax.mail.internet.InternetAddress; 12 import javax.mail.internet.MimeMessage; 13 import javax.mail.internet.MimeMultipart; 14 import javax.mail.internet.MimeUtility; 15 16 /** 17 * 18 * @author Administrator 19 * 20 */ 21 public class HTMLSender { 22 private MimeMessage message; 23 private Properties props; 24 private Session session; 25 private String name = ""; 26 private String password = ""; 27 28 public HTMLSender(String host,String name,String password) 29 { 30 this.name = name; 31 this.password = password; 32 props = System.getProperties(); 33 34 props.put("mail.smtp.host", host); 35 props.put("mail.smtp.auth","true"); 36 MyAuthenticator auth = new MyAuthenticator(name,password); 37 session = Session.getDefaultInstance(props,auth); 38 39 message = new MimeMessage(session); 40 new MimeMultipart(); 41 } 42 43 public void setFrom(String from) 44 { 45 try 46 { 47 message.setFrom(new InternetAddress(from)); 48 } 49 catch (AddressException e) 50 { 51 e.printStackTrace(); 52 } 53 catch (MessagingException e) 54 { 55 e.printStackTrace(); 56 } 57 } 58 59 public void setTo(String to) 60 { 61 try 62 { 63 message.setRecipients(Message.RecipientType.TO,InternetAddress.parse(to)); 64 } 65 catch(AddressException e) 66 { 67 e.printStackTrace(); 68 } 69 catch(MessagingException e) 70 { 71 e.printStackTrace(); 72 } 73 } 74 75 public void setSubject(String subject) 76 { 77 try 78 { 79 message.setSubject(subject); 80 } 81 catch(Exception e) 82 { 83 e.printStackTrace(); 84 } 85 } 86 87 public void setContect(String content) 88 { 89 try 90 { 91 message.setContent(content,"text/html;charset=utf-8"); 92 } 93 catch(Exception e) 94 { 95 e.printStackTrace(); 96 } 97 } 98 99 public boolean send() 100 { 101 try 102 { 103 Transport transport = session.getTransport("smtp"); 104 transport.connect((String)props.get("mail.smtp.host"),name,password); 105 transport.sendMessage(message, message.getRecipients(Message.RecipientType.TO)); 106 transport.close(); 107 return true; 108 } 109 catch(NoSuchProviderException e) 110 { 111 e.printStackTrace(); 112 return false; 113 } 114 catch(MessagingException e) 115 { 116 e.printStackTrace(); 117 return false; 118 } 119 } 120 }
2:MyAuthenticator类
1 package com.txq.mail; 2 3 import javax.mail.Authenticator; 4 import javax.mail.PasswordAuthentication; 5 6 7 public class MyAuthenticator extends Authenticator{ 8 String name; 9 String password; 10 public MyAuthenticator(String name,String pasword) 11 { 12 this.name = name; 13 this.password = pasword; 14 getPasswordAuthentication(); 15 } 16 protected PasswordAuthentication getPasswordAuthentication() 17 { 18 return new PasswordAuthentication(name,password); 19 } 20 }
3:MailAction类,前两个类只要完整的移至到你的项目中就可以(要把第一行对应的包名改一下),下边这个类,只要把带注释的内容修改为自己需要的就可以了;
1 package com.txq.action; 2 3 import java.io.PrintWriter; 4 5 import com.opensymphony.xwork2.ActionSupport; 6 import com.txq.mail.HTMLSender; 7 8 public class MailAction extends ActionSupport { 9 private String email; 10 public String sendEmail(){ 11 //代理主机-新浪 12 String host = "smtp.sina.cn"; 13 //帐号-新浪帐号 14 String name = "qqsinabaidu"; 15 //密码-新浪密码 16 String password = "baidu360"; 17 //创建发送邮件对象 18 HTMLSender mail = new HTMLSender(host,name,password); 19 //发邮帐号 20 mail.setFrom("qqsinabaidu@sina.cn"); 21 //收邮帐号 22 mail.setTo("youxiangzhanghe@qq.com"); 23 //邮件主题 24 mail.setSubject("哈哈"); 25 //邮件内容 26 mail.setContect("发送邮件的程序~"); 27 28 if(mail.send()) 29 { 30 return SUCCESS; 31 } 32 else 33 { 34 return "error"; 35 } 36 } 37 public String getEmail() { 38 return email; 39 } 40 public void setEmail(String email) { 41 this.email = email; 42 } 43 }
