JavaMail(一):利用JavaMail发送简单邮件
JavaMail，提供给开发者处理电子邮件相关的编程接口。它是Sun发布的用来处理email的API。它可以方便地执行一些常用的邮件传输。但它并没有包含在JDK中，要使用JavaMail首先要下载javax.mail.jar下载地址：https://javaee.github.io/javamail/
自定义验证：
/** * 自定义验证 * @author fly * @时间 2017-05-09 * */ public class MyAuthenticator extends Authenticator{ private String userName; private String password; public MyAuthenticator() { } public MyAuthenticator(String userName, String password) { this.userName = userName; this.password = password; } @Override protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(userName, password); } }
封装发邮件信息：
/** * 封装发邮件信息 * @author fly * @时间 2017-05-09 */ 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 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 getPassword() { return password; } public void setPassword(String password) { this.password = password; } 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; } }
封装发送邮件代码
/** * 封装发送邮件代码 * @author fly * @时间 2017-05-09 * */ public class Email { /** * 以文本格式发送邮件 * @param mailInfo 待发送邮件信息 * @throws Exception */ public static void 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.getDefaultInstance(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); } /** * 以HTML格式发送邮件 * @param mailInfo 待发送邮件信息 * @throws Exception */ public static void sendHtmlMail(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.getDefaultInstance(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()); Multipart mainPart = new MimeMultipart(); // 创建一个包含HTML内容的MimeBodyPart BodyPart html = new MimeBodyPart(); 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); }
测试程序：
public class JavaMailTest { public static void main(String[] args) {
//设置邮件相关信息 MailSenderInfo mailInfo = new MailSenderInfo(); mailInfo.setMailServerHost("smtp.163.com"); mailInfo.setMailServerPort("25"); mailInfo.setValidate(true); mailInfo.setUserName("qfanliyan@163.com"); mailInfo.setPassword(""); // 您的邮箱密码,若你的邮箱开启了客户端授权密码，则此处是您的客户端授权密码 mailInfo.setFromAddress("qfanliyan@163.com"); mailInfo.setToAddress("ifanliyan@qq.com"); mailInfo.setSubject("这是一封测试邮件"); mailInfo.setContent("你好！这是一封测试邮件"); try { Email.sendTextMail(mailInfo); //Email.sendHtmlMail(mailInfo); } catch (Exception e) { e.printStackTrace(); } } }
发送成功截图如下：
