邮件服务是一般系统的基本功能，本例使用163免费邮箱发送
1.邮件信息类（MailSenderInfo ）
package sendEmail.email;
import java.util.Properties;
/**
* 邮件信息设置
* @author Administrator
*
*/
public class MailSenderInfo {
private String mailServerHost ; //发送邮件主机
private String mailServerPort ; //发送端口
private String fromAddress ; //邮件发送者的地址（邮箱）
private String toAddress ; //接收者的地址（邮箱）
//登录邮件发送服务器的用户名和密码
private String userName ;
private String passwrod ;
//是否需要身份验证
private boolean validate = false ;
//邮件主题
private String subject ;
//邮件内容
private String content ;
//邮件附件
private String[] attachFileNames ;
/*
* 获取邮件会话属性
*/
public Properties getProperties(){
Properties p = new Properties();
p.put("mail.smtp.host", this.mailServerHost);
// p.put("mail.smtp.port", this.mailServerPort);
p.put("mail.sender.username", userName);
p.put("mail.sender.password", passwrod);
return p ;
}
public String getMailServerHost() {
return mailServerHost;
}
public void setMailServerHost(String mailServerHost) {
this.mailServerHost = mailServerHost;
}
public String getMailServerPort() {
return mailServerPort;
}
public void setMailServerPort(String mailServerPort) {
this.mailServerPort = mailServerPort;
}
public String getFromAddress() {
return fromAddress;
}
public void setFromAddress(String fromAddress) {
this.fromAddress = fromAddress;
}
public String getToAddress() {
return toAddress;
}
public void setToAddress(String toAddress) {
this.toAddress = toAddress;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPasswrod() {
return passwrod;
}
public void setPasswrod(String passwrod) {
this.passwrod = passwrod;
}
public boolean isValidate() {
return validate;
}
public void setValidate(boolean validate) {
this.validate = validate;
}
public String getSubject() {
return subject;
}
public void setSubject(String subject) {
this.subject = subject;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
public String[] getAttachFileNames() {
return attachFileNames;
}
public void setAttachFileNames(String[] attachFileNames) {
this.attachFileNames = attachFileNames;
}
}
2. 服务类（SimpleMailSender）
package sendEmail.email;
import java.util.Date;
import java.util.Properties;
import javax.mail.Address;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.BodyPart;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
/**
* 发送邮件格式设置
* @author Administrator
*
*/
public class SimpleMailSender {
/**
* 以(text)(文本格)式发送邮件
* @param mailInfo 待发送的邮件的信息
*/
public boolean sendTextMail(MailSenderInfo mailInfo){
Properties pro = mailInfo.getProperties();
Session sendMailSession = Session.getInstance(pro) ;
try {
// 根据session创建一个邮件消息
Message mailMessage = new MimeMessage(sendMailSession);
// 创建邮件发送者地址
Address from = new InternetAddress(mailInfo.getFromAddress());
// 设置邮件消息的发送者
mailMessage.setFrom(from);
// 创建邮件的接收者地址，并设置到邮件消息中
Address to = new InternetAddress(mailInfo.getToAddress());
mailMessage.setRecipient(Message.RecipientType.TO,to);
// 设置邮件消息的主题
mailMessage.setSubject(mailInfo.getSubject());
// 设置邮件消息发送的时间
mailMessage.setSentDate(new Date());
// 设置邮件消息的主要内容
String mailContent = mailInfo.getContent();
mailMessage.setText(mailContent);
// 发送邮件
mailMessage.saveChanges();
Transport transport = sendMailSession.getTransport("smtp");
transport.connect(mailInfo.getMailServerHost(), mailInfo.getUserName(), mailInfo.getPasswrod());
transport.sendMessage(mailMessage,mailMessage.getAllRecipients());
return true;
} catch (MessagingException ex) {
ex.printStackTrace();
}
return false;
}
/**
* 以html格式发送邮件
* @param mailInfo 待发送的邮件信息
*/
public static boolean sendHtmlMail(MailSenderInfo mailInfo){
Properties pro = mailInfo.getProperties();
// 根据邮件会话属性和密码验证器构造一个发送邮件的session
Session sendMailSession = Session.getDefaultInstance(pro);
try {
// 根据session创建一个邮件消息
Message mailMessage = new MimeMessage(sendMailSession);
// 创建邮件发送者地址
Address from = new InternetAddress(mailInfo.getFromAddress());
// 设置邮件消息的发送者
mailMessage.setFrom(from);
// 创建邮件的接收者地址，并设置到邮件消息中
Address to = new InternetAddress(mailInfo.getToAddress());
// Message.RecipientType.TO属性表示接收者的类型为TO
mailMessage.setRecipient(Message.RecipientType.TO,to);
// 设置邮件消息的主题
mailMessage.setSubject(mailInfo.getSubject());
// 设置邮件消息发送的时间
mailMessage.setSentDate(new Date());
// MiniMultipart类是一个容器类，包含MimeBodyPart类型的对象
Multipart mainPart = new MimeMultipart();
// 创建一个包含HTML内容的MimeBodyPart
BodyPart html = new MimeBodyPart();
// 设置HTML内容
html.setContent(mailInfo.getContent(), "text/html; charset=utf-8");
mainPart.addBodyPart(html);
// 将MiniMultipart对象设置为邮件内容
mailMessage.setContent(mainPart);
// 发送邮件
mailMessage.saveChanges();
Transport transport = sendMailSession.getTransport("smtp");
transport.connect(mailInfo.getMailServerHost(), mailInfo.getUserName(), mailInfo.getPasswrod());
transport.sendMessage(mailMessage,mailMessage.getAllRecipients());
return true;
} catch (MessagingException ex) {
ex.printStackTrace();
}
return false;
}
}
3.测试类（MailTest）
package sendEmail.email;
/**
* 测试类
* @author Administrator
*
*/
public class MailTest {
public static void main(String[] args) {
//设置邮件
try {
MailSenderInfo mainInfo = new MailSenderInfo();
mainInfo.setMailServerHost("smtp.163.com");
mainInfo.setValidate(true);
mainInfo.setUserName("**************");
mainInfo.setPasswrod("********");
mainInfo.setFromAddress("********");
mainInfo.setToAddress("********");
mainInfo.setSubject("lalalala");
mainInfo.setContent("----");
SimpleMailSender.sendHtmlMail(mainInfo);//发送文体格式
} catch (Exception e) {
e.printStackTrace();
}
}
}
注意：
mainInfo.setPasswrod("********"); 不是登录163邮箱的密码，是163邮箱授权码。以上是关于java email 发送的主要内容，如果未能解决你的问题，请参考以下文章
