使用javaxmail发送邮件(带/不带附件,文本邮件/html邮件)

使用javaxmail发送邮件(带/不带附件,文本邮件/html邮件)_第1张图片


1.  先定义发送邮件所需要的一些基本信息MailSenderInfo.java

package com.unj.mail_send2;
  
import java.io.File;
import java.util.List;
import java.util.Properties;
  
public class MailSenderInfo {
    // 发送邮件的服务器的地址和端口,其实端口号可以不用指定
    private String mailServerHost="smtp.qq.com";
    private String mailServerPort = "25";
    // 邮件发送者的地址
    private String fromAddress="[email protected]";
    // 邮件接收者的地址
    private String toAddress="[email protected]";
    // 登陆邮件发送服务器的用户名和密码
    private String userName="[email protected]";
    private String password="wahaha";
    // 是否需要身份验证
    private boolean validate = true;
    // 邮件主题
    private String subject="subject";
    // 邮件的文本内容
    private String content="hehe";
    // 邮件附件的文件名
    private String[] attachFileNames;
    private List<File> fileList;
  
    /**
     * 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 void addFile(File file){
        fileList.add(file);
    }
    //然后是一些get/set方法
}


2. 然后编写验证模块

package com.unj.mail_send2;
 
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;
    }
 
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(userName, password);
    }
}

3.  最后是发送方法的编写,注意看加没加附件的差别
package com.unj.mail_send2;
 
import java.io.File;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import java.util.Properties;
 
import javax.activation.DataHandler;
import javax.activation.FileDataSource;
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 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 multPart = 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");
            multPart.addBodyPart(html);
            // ============添加附件操作=============/
            List<File> list = mailInfo.getFileList();
            if (list != null && list.size() > 0) {// 有附件
                for (File f : list) {
                    MimeBodyPart mbp = new MimeBodyPart();
                    FileDataSource fds = new FileDataSource(f.getAbsolutePath()); // 得到数据源
                    mbp.setDataHandler(new DataHandler(fds));
                    mbp.setFileName(f.getName());
                    multPart.addBodyPart(mbp);
                }
 
                list.clear();
            }
            // ============添加附件操作=============/
            // 将MiniMultipart对象设置为邮件内容
            mailMessage.setContent(multPart);
            // 发送邮件
            Transport.send(mailMessage);
            return true;
        } catch (MessagingException ex) {
            ex.printStackTrace();
        }
        return false;
    }
 
    public static void main(String[] args) {
        SimpleMailSender mailSender = new SimpleMailSender();
        MailSenderInfo mailInfo = new MailSenderInfo();
        List<File> fileList = new ArrayList<File>();
        fileList.add(new File("E:/devTools/webService_cxf/apache-cxf-2.7.0/bin/idl2wsdl.bat"));
        fileList.add(new File("E:/devTools/webService_cxf/apache-cxf-2.7.0/bin/wsdl2java.bat"));
        fileList.add(new File("E:/devTools/webService_cxf/apache-cxf-2.7.0/bin/wsdl2js.bat"));
        fileList.add(new File("E:/devTools/webService_cxf/apache-cxf-2.7.0/bin/wsdl2soap.bat"));
        mailInfo.setFileList(fileList);
        if (mailSender.sendTextMail(mailInfo)) {
            System.out.println("ok!");
        }
        if (mailSender.sendHtmlMail(mailInfo)) {
            System.out.println("ok too!");
        }
    }
 
}

其实,发送文本邮件和html格式的邮件区别就在于

mailMessage.setText(mailContent); 



mailMessage.setContent(a); 

 Multipart a = new MimeMultipart();

a.addBodyPart(b);

MimeBodyPart b = new MimeBodyPart();

b.setContent("xxx", "text/html; charset=utf-8");
