1.新建model

SendMail.java

import java.util.Properties;public class SendMail {    // 发送邮件的服务器的IP和端口    private String mailServerHost;　　　　//服务器名称，类似163的： smtp.163.com    private String mailServerPort = "25";　　　　//服务器端口号    private String fromAddress;　　　　//发送邮件的地址    private String addressName;　　　　//发送邮件的邮箱名称    private String toAddress;　　　　//收件人地址    private String userName;　　　　//和邮箱地址保持一致    private String password;　　　　　//邮件安全密码，网易的是客户端授权密码    private boolean validate = false;    private String subject;　　　　//邮件标题    private String content;    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 String getAddressName() {        return addressName;    }    public void setAddressName(String addressName) {        this.addressName = addressName;    }}

 

 

2.发送邮件实现类

MailSender.java

import javax.mail.*;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeBodyPart;import javax.mail.internet.MimeMessage;import javax.mail.internet.MimeMultipart;import java.io.UnsupportedEncodingException;import java.util.Date;import java.util.Properties;public class MailSender {    /**     * 以文本格式发送邮件     */    public boolean sendTextMail(SendMail mailInfo) {        // 判断是否需要身份认证        Authentication 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 Authentication(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 {            Message mailMessage = new MimeMessage(sendMailSession);            Address from = new InternetAddress(mailInfo.getFromAddress());            mailMessage.setFrom(from);            Address to = new InternetAddress(mailInfo.getToAddress());            mailMessage.setRecipient(Message.RecipientType.TO, to);            mailMessage.setSubject(mailInfo.getSubject());            mailMessage.setSentDate(new Date());            String mailContent = mailInfo.getContent();            mailMessage.setText(mailContent);            Transport.send(mailMessage);            return true;        } catch (MessagingException ex) {            ex.printStackTrace();        }        return false;    }    /**     * 以HTML格式发送邮件     */    public boolean sendHtmlMail(SendMail mailInfo) {        // 判断是否需要身份认证        Authentication authenticator = null;        Properties pro = mailInfo.getProperties();        if (mailInfo.isValidate()) {            authenticator = new Authentication(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);            mailMessage.setFrom(new InternetAddress(mailInfo.getFromAddress()));            //设置自定义发件人昵称            String nick="";            try {                nick=javax.mail.internet.MimeUtility.encodeText(mailInfo.getAddressName());            } catch (UnsupportedEncodingException e) {                e.printStackTrace();            }            mailMessage.setFrom(new InternetAddress(nick+" <"+mailInfo.getFromAddress()+">"));//            Address from = new InternetAddress(mailInfo.getFromAddress());//            mailMessage.setFrom(from);            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);            mailMessage.setSubject(mailInfo.getSubject());            mailMessage.setSentDate(new Date());            Multipart mainPart = new MimeMultipart();            BodyPart html = new MimeBodyPart();            html.setContent(mailInfo.getContent(), "text/html; charset=utf-8");            mainPart.addBodyPart(html);            mailMessage.setContent(mainPart);            Transport.send(mailMessage);            return true;        } catch (MessagingException ex) {            ex.printStackTrace();        }        return false;    }}

 

 

 3.邮件发送工具类

SendMailUtil.java

import java.util.HashMap;import java.util.Map;public class SendMailUtil {
    private static SendMail mail() {        SendMail mail = new SendMail();        mail.setMailServerHost("smtp.yeah.net");        mail.setMailServerPort("25");        mail.setValidate(true);        mail.setUserName("发送邮件的邮箱地址");        mail.setPassword("邮件服务器的客户端授权密码");        mail.setFromAddress("发送邮件的邮箱地址");        mail.setAddressName("邮箱名称");        mail.setSubject("标题");        return mail;    }    public static boolean checkEmail(String email) {
