导入jar
先下载 mail.jar,并将mail.jar添加到classpath即可。如果你使用的是JAVA EE SDK,则可以在C:\glassfishv3\glassfish\modules\mail.jar找到所需的jar包,同样需要添加的classpath。
邮件实体类
创建一个继承MailSenderInfo.java 记录发送邮件所需的各种信息,如发送邮件服务器的地址、端口号、发件人邮箱、收件人邮箱等等。代码如下:
import java.util.Properties;
public class MailSendInfo {
// 发送邮件的服务器的IP(或主机地址)
private String mailServerHost;
// 发送邮件的服务器的端口
private String mailServerPort = "25";
// 发件人邮箱地址
private String fromAddress;
// 收件人邮箱地址
private String toAddress;
// 登陆邮件发送服务器的用户名
private String userName;
// 登陆邮件发送服务器的密码
private String password;
// 是否需要身份验证
private boolean validate = false;
// 邮件主题
private String subject;
// 邮件的文本内容
private String content;
// 邮件附件的文件名
private String[] attachFileNames;
public Properties getProperties() {
Properties p = new Properties();
p.put("mail.smtp.host", this.mailServerHost);
p.put("mail.smtp.port", this.mailServerPort);
p.put("mail.smtp.auth", validate ? "true" : "false");
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 boolean isValidate() {
return validate;
}
public void setValidate(boolean validate) {
this.validate = validate;
}
public String[] getAttachFileNames() {
return attachFileNames;
}
public void setAttachFileNames(String[] fileNames) {
this.attachFileNames = fileNames;
}
public String getFromAddress() {
return fromAddress;
}
public void setFromAddress(String fromAddress) {
this.fromAddress = fromAddress;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
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 getSubject() {
return subject;
}
public void setSubject(String subject) {
this.subject = subject;
}
public String getContent() {
return content;
}
public void setContent(String textContent) {
this.content = textContent;
}
}
邮箱登录类
MyAuthenticator.java,邮箱用户名和密码认证器。代码如下:
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
public class MyAuthenticator extends Authenticator{
private String userName;//用户名
private String password;//密码
public MyAuthenticator() {
}
public MyAuthenticator(String userName,String password){
this.userName = userName;
this.password = password;
}
/** 用作登录校验的,以确保你对该邮箱有发送邮件的权利*/
@Override
protected PasswordAuthentication getPasswordAuthentication(){
return new PasswordAuthentication(userName, password);
}
}
发送邮件类
SimpleMailSender.java,用来发送邮件类。代码如下:
import java.util.Date;
import java.util.Properties;
import javax.mail.Address;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
public class SimpleMailSender {
public boolean sendTextMail(MailSendInfo mailInfo) {
// 判断是否需要身份认证
MyAuthenticator authenticator = null;
Properties pro = mailInfo.getProperties();
if (mailInfo.isValidate()) {
// 如果需要身份认证,则创建一个密码验证器
authenticator = new MyAuthenticator(mailInfo.getUserName(), mailInfo.getPassword());
}
// 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, authenticator);
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
Transport.send(mailMessage);
return true;
} catch (MessagingException ex) {
ex.printStackTrace();
}
return false;
}
public static boolean sendHtmlMail(MailSendInfo mailInfo) {
// 判断是否需要身份认证
MyAuthenticator authenticator = null;
Properties pro = mailInfo.getProperties();
// 如果需要身份认证,则创建一个密码验证器
if (mailInfo.isValidate()) {
authenticator = new MyAuthenticator(mailInfo.getUserName(), mailInfo.getPassword());
}
// 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, authenticator);
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
Transport.send(mailMessage);
return true;
} catch (MessagingException ex) {
ex.printStackTrace();
}
return false;
}
}
测试
接下来就是见证奇迹的时刻了,代码如下:
public class SendMailDemo {
// public static void main(String[] args) {
public void doSend(){
// 设置邮件服务器信息
MailSendInfo mailInfo = new MailSendInfo();
mailInfo.setMailServerHost("smtp.163.com");
mailInfo.setMailServerPort("25");
mailInfo.setValidate(true);
// 邮箱用户名
mailInfo.setUserName("*****@163.com");
// 邮箱密码
mailInfo.setPassword("************");
// 发件人邮箱
mailInfo.setFromAddress("*****@163.com");
// 收件人邮箱
mailInfo.setToAddress("***********@126.com");
// 邮件标题
mailInfo.setSubject("商务合作邮件提醒");
// 邮件内容
StringBuffer buffer = new StringBuffer();
buffer.append("蜡笔分期欢迎您提供的商务合作\n");
buffer.append("来自***的商务合作方案");
mailInfo.setContent(buffer.toString());
// 发送邮件
SimpleMailSender sms = new SimpleMailSender();
// 发送文体格式
//sms.sendTextMail(mailInfo);
// 发送html格式
boolean flg = SimpleMailSender.sendHtmlMail(mailInfo);
if(flg){
System.out.println("邮件发送成功");
}else{
System.out.println("邮件发送失败");
}
}
}
