发送邮件，加附件

需要参考3篇文章

第一篇，这个是基本代码

转载自：http://dove19900520.iteye.com/blog/2005303

运行后出现下面异常

异常：Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream

第二篇
http://www.blogjava.net/hwpok/archive/2009/04/02/263599.html
按照那个路径删除javaee.jar中的mail这个文件夹

第三篇

下载 mail.jar和activation.jar

今天闲着无事，研究了一下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：

Java代码  


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

 

Java代码  


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：

Java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)

    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

        }  

        // 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 {

            }  

              

            // 设置邮件抄送者地址  

            String[] toCCs = senderInfo.getToCarbonCopyAddress();

            }
