发送电子邮件 1----javax.mail

javaMail发送电子邮件的方法，自己总结了个步骤：

1、首先需要获取发送邮件的Session对象

Session session = Session.getDefaultInstance(properties,authorcator);

2、根据session对象，获取待发送的邮件消息

MimeMessage mimeMessage = new MimeMessage(session);

3、设置发件人，收件人，标题，邮件内容，附件，发送时间等；

4、利用Transport发送邮件

 

以下是居然的实现代码：

1、邮件信息类：

package com.china.test.mail;

import java.util.Properties;

/**
 * 发送邮件需要使用的基本信息 
 * @author dove *
 */
public class MailSenderInfo {
	// 发送邮件的服务器的IP
    private String mailServerHost;    
    // 发送邮件的服务器的端口    
    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;
    // 邮件密送接收者的地址
    private String[] toBlindCarbonCopyAddress;
    // 邮件抄送接收者的地址
    private String[] toCarbonCopyAddress;
    // 登陆邮件发送服务器的用户名
    private String userName;
    // 登陆邮件发送服务器的密码    
    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 pro = new Properties();
		pro.put("mail.smtp.host", this.mailServerHost);
		pro.put("mail.smtp.port", this.mailServerPort);
		pro.put("mail.smtp.auth", validate ? "true" : "false");
		return pro;
	}
    
	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;
	}

	public String[] getToBlindCarbonCopyAddress() {
		return toBlindCarbonCopyAddress;
	}

	public void setToBlindCarbonCopyAddress(String[] toBlindCarbonCopyAddress) {
		this.toBlindCarbonCopyAddress = toBlindCarbonCopyAddress;
	}

	public String[] getToCarbonCopyAddress() {
		return toCarbonCopyAddress;
	}

	public void setToCarbonCopyAddress(String[] toCarbonCopyAddress) {
		this.toCarbonCopyAddress = toCarbonCopyAddress;
	}
	
}

 

2、身份验证类

package com.china.test.mail;

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
/**
 * 身份验证器
 * @author dove
 *
 */
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);
	}
	
	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;
	}
}

 

3、发送邮件类

该类有两个功能，一个是发送普通文本邮件；一个是发送html邮件，两者的本质是相同的，mime类型有所区别而已，具体请看代码：

package com.china.test.mail;

import java.io.UnsupportedEncodingException;
import java.util.Date;
import java.util.Properties;

import javax.activation.DataHandler;
import javax.activation.DataSource;
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.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
import javax.mail.internet.MimeUtility;

/**
 * 简单邮件发送器
 * @author dove *
 */
public class SimpleMailSender {
    /**
     * 以文本格式发送邮件 (支持群发,带附件)
     * @param senderInfo 待发送的邮件的信息
     * @return
     */
    public static boolean sendMail(MailSenderInfo senderInfo){
        boolean flag = false;

        // 判断是否需要身份验证
        MyAuthenticator authenticator = null;
        Properties props = senderInfo.getProperties();
        if(senderInfo.isValidate()){
            // 如果需要身份认证，则创建一个密码验证器
            authenticator = new MyAuthenticator(senderInfo.getUserName(), senderInfo.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(props, authenticator);

        try {
            // 根据session创建一个邮件消息
            Message sendMailMessage = new MimeMessage(sendMailSession);
            // 创建邮件发送者地址
            Address from = new InternetAddress(senderInfo.getFromAddress());
            // 设置邮件消息的发送者
            sendMailMessage.setFrom(from);

            // 创建邮件接收者地址
            String[] tos = senderInfo.getToAddress();
            if(tos != null && tos.length != 0){
                InternetAddress[] to = new InternetAddress[tos.length];
                // 设置邮件消息的发送者
                for (int i = 0; i < tos.length; i++) {

                }
                sendMailMessage.setRecipients(Message.RecipientType.TO, to);
            }

            // 设置邮件抄送者地址
            String[] toCCs = senderInfo.getToCarbonCopyAddress();
            if(toCCs != null && toCCs.length != 0){
                InternetAddress[] toCC = new InternetAddress[toCCs.length];

                }
                sendMailMessage.addRecipients(Message.RecipientType.BCC, toBCC);
            }

            // 设置邮件主题
