Java发送邮件javax.mail的实现方法_Java教程-查字典教程网

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

package com.lgf.Email; import java.util.Date; public class EmailMessage { /** * 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 public static String TO = "xxx@xxx.com"; // 发件人邮箱 public static String FROM = "xxx@xxx.com"; public static String FROM_NAME = "xxx"; // 抄送人 public static String CC="xxx@nxxx.com"; // 暗送人 public static String BCC="xxx@nxxx.com"; // 邮件的类型 public static String Email_Content = "text/plain"; // 邮件标题 public static String Email_Subject = "Test Email With JavaMail"; // 邮件头 public static String Email_Header = "This Is Email Header"; // 内容 public static String Email_Body = "<a href="http://www.baidu.com">This Is Email Body</a>"; // 服务器比如QQ的可以设置为smtp.qq.com public static String Email_Host = "smtp.xxx.com"; // 发送时间 public static Date sendDate = new Date(); // 是否需要验证用户名和密码 public static boolean validate = true; }

2. 服务器验证(就是一般登入时候的用户名和密码)

package com.lgf.Email; import javax.mail.Authenticator; import javax.mail.PasswordAuthentication; /** * 用户名和密码的验证 * @author lgf * */ public class MailAuthenticator extends Authenticator{ private String username="xxxxx"; private String password="xxxxx"; public MailAuthenticator() { super(); } /** * 设置验证的用户名和密码 */ public MailAuthenticator(String userName , String password) { super(); this.username = userName; this.password = password; } protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(this.username,this.password); } }

3. 发送邮件前设置信息和步骤

package com.lgf.Email; import java.util.Properties; import javax.activation.DataHandler; import javax.activation.DataSource; import javax.activation.FileDataSource; import javax.mail.Address; import javax.mail.Authenticator; import javax.mail.BodyPart; import javax.mail.Message; 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; import com.lgf.SendEmail.MailAuthenticator; public class SendEmail { /** * 发送普通邮件 * @throws Exception */ public void doSendNormalMail() { // 获取系统环境 Properties prop = new Properties(); Authenticator auth = 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 = new MailAuthenticator(); } // 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 Session session = Session.getDefaultInstance(prop, auth); // 在控制台显示Debug信息 session.setDebug(true); // 设置邮件对象 Message message = new MimeMessage(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 Address address = new InternetAddress(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 Address toAddress = new InternetAddress(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,new InternetAddress("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 (Exception e) { System.out.println("出错"); e.printStackTrace(); } } /** * 发送HTML格式的邮件 */ public void doSendHtmlMail() { // 获取系统环境 Properties prop = new Properties(); Authenticator auth = null; if (EmailMessage.validate) { // 邮件服务器认证用户名和密码 auth = new MailAuthenticator(); } // 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 Session session = Session.getDefaultInstance(prop, auth); // 设置邮件对象 Message message = new MimeMessage(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 Address address = new InternetAddress(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 Address toAddress = new InternetAddress(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,new InternetAddress("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 (Exception e) { System.out.println("出错"); e.printStackTrace(); } } /** * 发送带有附件格式的邮件 */ public void doSendAttachmentMail() { // 获取系统环境 Properties prop = new Properties(); Authenticator auth = null; if (EmailMessage.validate) { // 邮件服务器认证用户名和密码 auth = new MailAuthenticator(); } // 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 Session session = Session.getDefaultInstance(prop, auth); // 设置邮件对象 Message message = new MimeMessage(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 Address address = new InternetAddress(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 Address toAddress = new InternetAddress(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,new InternetAddress("xxx@xxx.com")); // 设置发送信息的内容下面为发送附件 message.setContent(EmailMessage.Email_Body, EmailMessage.Email_Content); BodyPart messageBodyPart = new MimeBodyPart(); messageBodyPart.setText("bodypart"); Multipart multipart = new MimeMultipart(); multipart.addBodyPart(messageBodyPart); messageBodyPart = new MimeBodyPart(); // 设置上传的资源 DataSource source = new FileDataSource("E:3.doc"); // 添加到 messageBodyPart.setDataHandler(new DataHandler(source)); // 设置文件名称,记得后缀名 messageBodyPart.setFileName("test.doc"); multipart.addBodyPart(messageBodyPart); message.setContent(multipart); // 保存上面添加的信息 message.saveChanges(); // 发送邮件 System.out.println("doSendAttachmentMail() 开始发送邮件……"); Transport.send(message); System.out.println("发送成功！"); } catch (Exception e) { System.out.println("出错"); e.printStackTrace(); } } /** * @param args */ public static void main(String[] args) { // new SendEmail().doSendNormalMail(); // new SendEmail().doSendHtmlMail(); new SendEmail().doSendAttachmentMail(); } }
