java邮件解析3

比较完整的例子：

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)

* @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

}

// 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 {
