1. 先定義發送郵件所需要的一些基本資訊MailSenderInfo.java
package com.unj.mail_send2;
import java.io.File;
import java.util.List;
import java.util.Properties;
public class MailSenderInfo {
// 發送郵件的伺服器的位址和端口，其實端口号可以不用指定
private String mailServerHost="smtp.qq.com";
private String mailServerPort = "25";
// 郵件發送者的位址
private String fromAddress="[email protected]";
// 郵件接收者的位址
private String toAddress="[email protected]";
// 登陸郵件發送伺服器的使用者名和密碼
private String userName="[email protected]";
private String password="wahaha";
// 是否需要身份驗證
private boolean validate = true;
// 郵件主題
private String subject="subject";
// 郵件的文本内容
private String content="hehe";
// 郵件附件的檔案名
private String[] attachFileNames;
private List<File> fileList;
/**
* 獲得郵件會話屬性
*/
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);
}
//然後是一些get/set方法
}
2. 然後編寫驗證子產品
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. 最後是發送方法的編寫，注意看加沒加附件的差别
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 {
/**
* 以文本格式發送郵件
*
* @param mailInfo
* 待發送的郵件的資訊
*/
public boolean sendTextMail(MailSenderInfo mailInfo) {
// 判斷是否需要身份認證
MyAuthenticator authenticator = null;
Properties pro = mailInfo.getProperties();
if (mailInfo.isValidate()) {
// 如果需要身份認證，則建立一個密碼驗證器
authenticator = new MyAuthenticator(mailInfo.getUserName(),
mailInfo.getPassword());
}
// 根據郵件會話屬性和密碼驗證器構造一個發送郵件的session
Session sendMailSession = Session
.getDefaultInstance(pro, authenticator);
try {
// 根據session建立一個郵件消息
Message mailMessage = new MimeMessage(sendMailSession);
// 建立郵件發送者位址
Address from = new InternetAddress(mailInfo.getFromAddress());
// 設定郵件消息的發送者
mailMessage.setFrom(from);
// 建立郵件的接收者位址，并設定到郵件消息中
Address to = new InternetAddress(mailInfo.getToAddress());
mailMessage.setRecipient(Message.RecipientType.TO, to);
// 設定郵件消息的主題
mailMessage.setSubject(mailInfo.getSubject());
// 設定郵件消息發送的時間
mailMessage.setSentDate(new Date());
// 設定郵件消息的主要内容
String mailContent = mailInfo.getContent();
mailMessage.setText(mailContent);
// 發送郵件
Transport.send(mailMessage);
return true;
} catch (MessagingException ex) {
ex.printStackTrace();
}
return false;
}
/**
* 以HTML格式發送郵件
*
* @param mailInfo
* 待發送的郵件資訊
*/
public boolean sendHtmlMail(MailSenderInfo mailInfo) {
// 判斷是否需要身份認證
MyAuthenticator authenticator = null;
Properties pro = mailInfo.getProperties();
// 如果需要身份認證，則建立一個密碼驗證器
if (mailInfo.isValidate()) {
authenticator = new MyAuthenticator(mailInfo.getUserName(),
mailInfo.getPassword());
}
// 根據郵件會話屬性和密碼驗證器構造一個發送郵件的session
Session sendMailSession = Session
.getDefaultInstance(pro, authenticator);
try {
// 根據session建立一個郵件消息
Message mailMessage = new MimeMessage(sendMailSession);
// 建立郵件發送者位址
Address from = new InternetAddress(mailInfo.getFromAddress());
// 設定郵件消息的發送者
mailMessage.setFrom(from);
// 建立郵件的接收者位址，并設定到郵件消息中
Address to = new InternetAddress(mailInfo.getToAddress());
// Message.RecipientType.TO屬性表示接收者的類型為TO
mailMessage.setRecipient(Message.RecipientType.TO, to);
// 設定郵件消息的主題
mailMessage.setSubject(mailInfo.getSubject());
// 設定郵件消息發送的時間
mailMessage.setSentDate(new Date());
// MiniMultipart類是一個容器類，包含MimeBodyPart類型的對象
Multipart multPart = new MimeMultipart();
// 建立一個包含HTML内容的MimeBodyPart
BodyPart html = new MimeBodyPart();
// 設定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()); // 得到資料源
mbp.setDataHandler(new DataHandler(fds));
mbp.setFileName(f.getName());
multPart.addBodyPart(mbp);
}
list.clear();
}
// ============添加附件操作=============/
// 将MiniMultipart對象設定為郵件内容
mailMessage.setContent(multPart);
// 發送郵件
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!");
}
}
}
其實，發送文本郵件和html格式的郵件差別就在于
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");
