JavaMail發送郵件

其實Java應用程序發送 E-mail 非常簡單

1.首先下載mail.jar 包導入工程

2.創建4個類  MailSenderInfo.java  MyAuthenticator.java  SimpleMailSender.java SendEmail.java

3.源碼下載路徑  JavaMail.jar   可以直接運行

   MailSenderInfo 類代碼如下：

package com.javacto.mail;

import java.util.Properties;
/**  
* 發送郵件需要使用的基本信息  
*/ 
public class MailSenderInfo {
	// 發送郵件的服務器的IP和端口   
    private String mailServerHost;   
    private String mailServerPort = "25";   
    // 郵件發送者的地址   
    private String fromAddress;   
    // 郵件接收者的地址   
    private String toAddress;   
    // 登陸郵件發送服務器的用戶名和密碼   
    private String userName;   
    private String password;   
    // 是否需要身份驗證   
    private boolean validate = false;   
    // 郵件主題   
    private String subject;   
    // 郵件的文本內容   
    private String content;   
    // 郵件附件的文件名   
    private String[] attachFileNames;     
    /**  
      * 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 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 boolean isValidate() {   
      return validate;   
    }  
    public void setValidate(boolean validate) {   
      this.validate = validate;   
    }  
    public String[] getAttachFileNames() {   
      return attachFileNames;   
    }  
    public void setAttachFileNames(String[] fileNames) {   
      this.attachFileNames = fileNames;   
    }  
    public String getFromAddress() {   
      return fromAddress;   
    }   
    public void setFromAddress(String fromAddress) {   
      this.fromAddress = fromAddress;   
    }  
    public String getPassword() {   
      return password;   
    }  
    public void setPassword(String password) {   
      this.password = password;   
    }  
    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 getSubject() {   
      return subject;   
    }  
    public void setSubject(String subject) {   
      this.subject = subject;   
    }  
    public String getContent() {   
      return content;   
    }  
    public void setContent(String textContent) {   
      this.content = textContent;   
    }   
}

MyAuthenticator  類代碼如下：

package com.javacto.mail;
import javax.mail.*;
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;   
	    }   
	    protected PasswordAuthentication getPasswordAuthentication(){  
	        return new PasswordAuthentication(userName, password);  
	    }  
}

 SimpleMailSender  類代碼如下：

package com.javacto.mail;

SendEmail  類代碼如下：

package com.javacto.mail;

public class SendEmail {

		MailSenderInfo mailInfo = new MailSenderInfo();
		mailInfo.setMailServerHost("smtp.163.com");
		mailInfo.setMailServerPort("25");
		mailInfo.setValidate(true);
		mailInfo.setUserName("[email protected]");//登陸郵件發送服務器的用戶名
		mailInfo.setPassword("*****");// 您的郵箱密碼
		mailInfo.setFromAddress("[email protected]");//郵件發送者的地址
		mailInfo.setToAddress("[email protected]");//郵件接收者的地址
		mailInfo.setSubject("java一對一輔導");
		mailInfo.setContent("學習網址：javacto.taobao.com");
		// 這個類主要來發送郵件
		SimpleMailSender sms = new SimpleMailSender();
		sms.sendTextMail(mailInfo);// 發送文體格式
		//sms.sendHtmlMail(mailInfo);// 發送html格式
	}
