android 使用JavaMail

今天学习了一下JavaMail,javamail发送邮件确实是一个比较麻烦的问题不用第三方邮件程序。为了以后使用方便,自己写了段代码微笑

Javamail-Android配置步骤:

  1. 下载Android版本JavaMail包,additional.jar、mail.jar和activation.jar,下载地址JavaMail-Android

  2. 在项目与src同一目录级别下,新建文件夹lib,将下载的3个jar包放入该文件夹

  3. 右键->Properties->Java Build Path->Libraries,选择Add External JARs,找到项目下lib目录的3个jar包


我的代码有三个类: 
第一个类:MailSenderInfo.java

package com.util.mail;

/** 

* 发送邮件需要使用的基本信息 

*/ 

import java.util.Properties; 

public class MailSenderInfo { 

	// 发送邮件的服务器的IP和端口 

	private String mailServerHost; 

	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; 

	// 登陆邮件发送服务器的用户名和密码 

	private String userName; 

	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 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; 

	} 

}

        public void setReceivers(String[] receivers) {

            this.receivers = receivers;

        }

    }

}

第三个类:MyAuthenticator.java

package com.util.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);

    }

}

下面给出使用上面三个类的代码:

public static void main(String[] args){

         //这个类主要是设置邮件

      MultiMailSenderInfo mailInfo = new MultiMailSenderInfo(); 

      mailInfo.setMailServerHost("smtp.163.com"); 

      mailInfo.setMailServerPort("25"); 

      mailInfo.setValidate(true); 

      mailInfo.setUserName("[email protected]"); 

      mailInfo.setPassword("**********");//您的邮箱密码 

      mailInfo.setFromAddress("[email protected]"); 

      mailInfo.setToAddress("[email protected]"); 

      mailInfo.setSubject("设置邮箱标题"); 

      mailInfo.setContent("设置邮箱内容");

      String[] receivers = new String[]{"***@163.com", "***@tom.com"}; 

      String[] ccs = receivers; mailInfo.setReceivers(receivers); 

      mailInfo.setCcs(ccs); 

      //这个类主要来发送邮件 

      MultiMailsender sms = new MultiMailsender(); 

      sms.sendTextMail(mailInfo);//发送文体格式 

      MultiMailsender.sendHtmlMail(mailInfo);//发送html格式 

      MultiMailsender.sendMailtoMultiCC(mailInfo);//发送抄送 

最后,给出朋友们几个注意的地方: 
1、使用此代码你可以完成你的javamail的邮件发送功能、发多个邮箱。三个类缺一不可。 
2、这三个类我打包是用的com.util.mail包,如果不喜欢,你可以自己改,但三个类文件必须在同一个包中 
3、不要使用你刚刚注册过的邮箱在程序中发邮件,如果你的163邮箱是刚注册不久,那你就不要使用“smtp.163.com”。因为你发不出去。刚注册的邮箱是不会给你这种权限的,也就是你不能通过验证。要使用你经常用的邮箱,而且时间比较长的。 
4、另一个问题就是mailInfo.setMailServerHost("smtp.163.com");mailInfo.setFromAddress("[email protected]");这两句话。即如果你使用163smtp服务器,那么发送邮件地址就必须用163的邮箱,如果不的话,是不会发送成功的。 
5、关于javamail验证错误的问题,网上的解释有很多,但我看见的只有一个。就是我的第三个类。你只要复制全了代码,我想是不会有问题的。

6、 然后在Android项目中添加网络访问权限

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
