通过javamail发送邮件
最近做发送邮件的功能,以前没有接触过,在网上找了个例子,很好用,现在分享下,直接复制就可以用
?
第一个类:
package cpecc.funds.common;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;/** * 简单邮件(不带附件的邮件)发送器 */ 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; } /** * 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; } }

第二个类:
package cpecc.funds.common;import javax.mail.*; 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);}}

第三个类:
package cpecc.funds.common;/** * 发送邮件需要使用的基本信息 */ 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; } public static void main(String[] args){ //这个类主要是设置邮件 MailSenderInfo mailInfo = new MailSenderInfo(); mailInfo.setMailServerHost("stmp.sina.com.cn"); mailInfo.setMailServerPort("25"); mailInfo.setValidate(true); mailInfo.setUserName("2335931ma@sina.com"); mailInfo.setPassword("mayijun");//您的邮箱密码 mailInfo.setFromAddress("2335931ma@sina.com"); mailInfo.setToAddress("2335931ma@sina.com"); mailInfo.setSubject("设置邮箱标题"); mailInfo.setContent("设置邮箱内容"); //这个类主要来发送邮件 SimpleMailSender sms = new SimpleMailSender(); sms.sendTextMail(mailInfo);//发送文体格式 sms.sendHtmlMail(mailInfo);//发送html格式}}

1、这里引用一个mail的jar包
2、注意jar包冲突问题,很多人都遇到过,因为项目里引用了J2ee的包,直接报没找到流方法的错误。解决办法就是,删除J2ee包里的activation和mail两个目录就可以了。

祝你们成功!
