Java发送邮件javax.mail的实现方法
直接上源码：
1.邮件的基本信息(方便就直接设置为静态了)
下面最好是做为一个javabean
packagecom.lgf.Email;
importjava.util.Date;
publicclassEmailMessage
{
/**
*邮件的信息,可以自己进行设置。
*为了方便直接全部设置为静态
*/
//收件人邮箱
publicstaticStringTO="xxx@xxx.com";
//发件人邮箱
publicstaticStringFROM="xxx@xxx.com";
publicstaticStringFROM_NAME="xxx";
//抄送人
publicstaticStringCC="xxx@nxxx.com";
//暗送人
publicstaticStringBCC="xxx@nxxx.com";
//邮件的类型
publicstaticStringEmail_Content="text/plain";
//邮件标题
publicstaticStringEmail_Subject="TestEmailWithJavaMail";
//邮件头
publicstaticStringEmail_Header="ThisIsEmailHeader";
//内容
publicstaticStringEmail_Body="<ahref=\"http://www.baidu.com\">ThisIsEmailBody</a>";
//服务器比如QQ的可以设置为smtp.qq.com
publicstaticStringEmail_Host="smtp.xxx.com";
//发送时间
publicstaticDatesendDate=newDate();
//是否需要验证用户名和密码
publicstaticbooleanvalidate=true;
}
2.服务器验证(就是一般登入时候的用户名和密码)
packagecom.lgf.Email;
importjavax.mail.Authenticator;
importjavax.mail.PasswordAuthentication;
/**
*用户名和密码的验证
*@authorlgf
*
*/
publicclassMailAuthenticatorextendsAuthenticator{
privateStringusername="xxxxx";
privateStringpassword="xxxxx";
publicMailAuthenticator(){
super();
}
/**
*设置验证的用户名和密码
*/
publicMailAuthenticator(StringuserName,Stringpassword){
super();
this.username=userName;
this.password=password;
}
protectedPasswordAuthenticationgetPasswordAuthentication()
{
returnnewPasswordAuthentication(this.username,this.password);
}
}
3.发送邮件前设置信息和步骤
packagecom.lgf.Email;
importjava.util.Properties;
importjavax.activation.DataHandler;
importjavax.activation.DataSource;
importjavax.activation.FileDataSource;
importjavax.mail.Address;
importjavax.mail.Authenticator;
importjavax.mail.BodyPart;
importjavax.mail.Message;
importjavax.mail.Multipart;
importjavax.mail.Session;
importjavax.mail.Transport;
importjavax.mail.internet.InternetAddress;
importjavax.mail.internet.MimeBodyPart;
importjavax.mail.internet.MimeMessage;
importjavax.mail.internet.MimeMultipart;
importcom.lgf.SendEmail.MailAuthenticator;
publicclassSendEmail
{
/**
*发送普通邮件
*@throwsException
*/
publicvoiddoSendNormalMail()
{
//获取系统环境
Propertiesprop=newProperties();
Authenticatorauth=null;
//判断发送邮件是否需要验证
if(EmailMessage.validate)
{
//邮件服务器认证用户名和密码
auth=newMailAuthenticator();
}
//添加必要的信息
prop.put("mail.smtp.host",EmailMessage.Email_Host);
prop.put("mail.smtp.auth","true");
//设置对话和邮件服务器进行通讯
Sessionsession=Session.getDefaultInstance(prop,auth);
//在控制台显示Debug信息
session.setDebug(true);
//设置邮件对象
Messagemessage=newMimeMessage(session);
try
{
//设置邮件主题
message.setSubject(EmailMessage.Email_Subject);
//设置邮件标题
message.setHeader("Header",EmailMessage.Email_Header);
//设置发送时间
message.setSentDate(EmailMessage.sendDate);
//设置发信人地址和名字
Addressaddress=newInternetAddress(EmailMessage.FROM,EmailMessage.FROM_NAME);
//把发件人信息添加到信息中
message.setFrom(address);
//设置发件人地址
AddresstoAddress=newInternetAddress(EmailMessage.TO);
//设置接收人地址
message.setRecipient(Message.RecipientType.TO,toAddress);
//设置多个收件人地址
//message.addRecipient(Message.RecipientType.TO,newInternetAddress("xxx@xxx.com"));
//设置邮件格式
message.setContent("Content",EmailMessage.Email_Content);
//设置邮件内容必须在设置文件格式后面
message.setText(EmailMessage.Email_Body);
//保存上面添加的信息
message.saveChanges();
//发送邮件
System.out.println("sendNormalEmail()开始发送邮件……");
Transport.send(message);
System.out.println("发送成功！");
}catch(Exceptione)
{
System.out.println("出错");
e.printStackTrace();
}
}
/**
*发送HTML格式的邮件
*/
publicvoiddoSendHtmlMail()
{
//获取系统环境
Propertiesprop=newProperties();
Authenticatorauth=null;
if(EmailMessage.validate)
{
//邮件服务器认证用户名和密码
auth=newMailAuthenticator();
}
//添加必要的信息
prop.put("mail.smtp.host",EmailMessage.Email_Host);
prop.put("mail.smtp.auth","true");
//设置对话和邮件服务器进行通讯
Sessionsession=Session.getDefaultInstance(prop,auth);
//设置邮件对象
Messagemessage=newMimeMessage(session);
try
{
//设置邮件主题
message.setSubject(EmailMessage.Email_Subject);
//设置邮件标题
message.setHeader("Header",EmailMessage.Email_Header);
//设置发送时间
message.setSentDate(EmailMessage.sendDate);
//设置发信人地址和名字
Addressaddress=newInternetAddress(EmailMessage.FROM,EmailMessage.FROM_NAME);
//把发件人信息添加到信息中
message.setFrom(address);
//设置发件人地址
AddresstoAddress=newInternetAddress(EmailMessage.TO);
//设置接收人地址
message.setRecipient(Message.RecipientType.TO,toAddress);
//设置多个收件人地址
//message.addRecipient(Message.RecipientType.TO,newInternetAddress("xxx@xxx.com"));
//设置发送信息的内容下面为发送hmml
//设置邮件格式
EmailMessage.Email_Content="text/html;charset=utf-8";
message.setContent(EmailMessage.Email_Body,EmailMessage.Email_Content);
//保存上面添加的信息
message.saveChanges();
//发送邮件
System.out.println("doSendHtmlMail()开始发送邮件……");
Transport.send(message);
System.out.println("发送成功！");
}catch(Exceptione)
{
System.out.println("出错");
e.printStackTrace();
}
}
/**
*发送带有附件格式的邮件
*/
publicvoiddoSendAttachmentMail()
{
//获取系统环境
Propertiesprop=newProperties();
Authenticatorauth=null;
if(EmailMessage.validate)
{
//邮件服务器认证用户名和密码
auth=newMailAuthenticator();
}
//添加必要的信息
prop.put("mail.smtp.host",EmailMessage.Email_Host);
prop.put("mail.smtp.auth","true");
//设置对话和邮件服务器进行通讯
Sessionsession=Session.getDefaultInstance(prop,auth);
//设置邮件对象

//设置发信人地址和名字

//设置多个收件人地址

//设置发送信息的内容下面为发送附件
message.setContent(EmailMessage.Email_Body,EmailMessage.Email_Content);
BodyPartmessageBodyPart=newMimeBodyPart();
messageBodyPart.setText("bodypart");
Multipartmultipart=newMimeMultipart();
multipart.addBodyPart(messageBodyPart);
