JAVA SMTP例子
一、SimpleMailSender.java
package org.fh.util.mail; import java.util.Date; import java.util.Properties; import javax.mail.Address; 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; /** * 说明：邮件发送器 * 作者：FH Admin * from：www.fhadmin.org */ public class SimpleMailSender { /** * 以文本格式发送邮件 * @param mailInfo 待发送的邮件的信息 */ public boolean sendTextMail(MailSenderInfo mailInfo) throws Exception { // 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.getInstance(pro, authenticator); // 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; } /** * 以HTML格式发送邮件 * * @param mailInfo 待发送的邮件信息 */ public boolean sendHtmlMail(MailSenderInfo mailInfo) throws Exception { // 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.getInstance(pro, authenticator); // 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; } /** * @param SMTP 邮件服务器 * @param PORT 端口 * @param EMAIL 本邮箱账号 * @param PAW 本邮箱密码 * @param toEMAIL 对方箱账号 * @param TITLE 标题 * @param CONTENT 内容 * @param TYPE 1：文本格式;2：HTML格式 */ public static void sendEmail(String SMTP, String PORT, String EMAIL, String PAW, String toEMAIL, String TITLE, String CONTENT, String TYPE) throws Exception { // 这个类主要是设置邮件 MailSenderInfo mailInfo = new MailSenderInfo(); mailInfo.setMailServerHost(SMTP); mailInfo.setMailServerPort(PORT); mailInfo.setValidate(true); mailInfo.setUserName(EMAIL); mailInfo.setPassword(PAW); mailInfo.setFromAddress(EMAIL); mailInfo.setToAddress(toEMAIL); mailInfo.setSubject(TITLE); mailInfo.setContent(CONTENT); // 这个类主要来发送邮件 SimpleMailSender sms = new SimpleMailSender(); if ("1".equals(TYPE)) { sms.sendTextMail(mailInfo); } else { sms.sendHtmlMail(mailInfo); } } public static void main(String[] args) { try { SimpleMailSender.sendEmail("smtp.qq.com","25","9376591@qq.com","授权码","93796591@qq.com","你好","<p>你好From JavaMail!</p>","2"); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
二、MyAuthenticator.java
package org.fh.util.mail; import javax.mail.Authenticator; import javax.mail.PasswordAuthentication; /** * 说明：发送邮件需要使用的基本信息 * 作者：FH Admin * from：www.fhadmin.org */ public class MyAuthenticator extends Authenticator{ String userName=null; String password=null; public MyAuthenticator(){ } public MyAuthenticator(String username, String password) { this.userName = username; this.password = password; } protected PasswordAuthentication getPasswordAuthentication(){ return new PasswordAuthentication(userName, password); } }
三、MailSenderInfo.java
package org.fh.util.mail; /** * 说明：发送邮件需要使用的基本信息 * 作者：FH Admin * from：www.fhadmin.org */ import java.util.Properties; public class MailSenderInfo { // 发送邮件的服务器的IP和端口 private String mailServerHost; private String mailServerPort = "25"; // 邮件发送者的地址 private String fromAddress; // 邮件接收者的地址 private String toAddress; // 登陆邮件发送服务器的用户名和密码 private String userName; 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; /** * 获得邮件会话属性 */ public Properties getProperties(){ Properties p = new Properties(); p.put("mail.smtp.host", this.mailServerHost); p.put("mail.smtp.port", this.mailServerPort); p.put("mail.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; } }
