施用JavaMail 发送邮件

使用JavaMail 发送邮件
在项目中，做登陆注册的时候，需要给注册用户发送邮件激活，简单整理了一下JavaMail发送邮件的功能，步骤如下：

第一步：创建一个邮件信息类

package mail;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;}}

package mail;import javax.mail.Authenticator;import javax.mail.PasswordAuthentication;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);}}

package mail;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 {/** * 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) {// 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sessionSession 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;}/** * 以HTML格式发送邮件 *  * @param mailInfo *            待发送的邮件信息 */public static boolean sendHtmlMail(MailSenderInfo 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sessionSession 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TOmailMessage.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MimeBodyPartBodyPart 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;}}

package mail;import java.io.UnsupportedEncodingException;import javax.mail.MessagingException;public class Send {public static void main(String[] args) throws UnsupportedEncodingException, MessagingException {MailSenderInfo mailInfo = new MailSenderInfo();mailInfo.setMailServerHost("smtp.qq.com");mailInfo.setMailServerPort("25");mailInfo.setValidate(true);mailInfo.setUserName("********@qq.com");mailInfo.setPassword("********");mailInfo.setFromAddress("********@qq.com");mailInfo.setToAddress("********@gmail.com");mailInfo.setSubject("中国最大的汽车观察网站 http://www.cheguancha.com");sun.misc.BASE64Encoder enc = new sun.misc.BASE64Encoder();mailInfo.setSubject("=?UTF-8?B?" + enc.encode(mailInfo.getSubject().getBytes("UTF-8")) + "?=");mailInfo.setContent("请点击如下链接激活账号http://www.cheguancha.com");SimpleMailSender.sendHtmlMail(mailInfo);}}
