Android 使用 JavaMail

openkk 8年前

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.

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;    }   } 

第二个类:MultiMailsender.java

            Properties pro = mailInfo.getProperties();            if (mailInfo.isValidate()) {             // 如果需要身份认证,则创建一个密码验证器               authenticator = new MyAuthenticator(mailInfo.getUserName(), mailInfo.getPassword());             }            // 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(pro,authenticator);             try {             // 根据session创建一个邮件消息             Message mailMessage = new MimeMessage(sendMailSession);             // 创建邮件发送者地址             Address from = new InternetAddress(mailInfo.getFromAddress());             // 设置邮件消息的发送者             mailMessage.setFrom(from);             // 创建邮件的接收者地址,并设置到邮件消息中             Address[] tos = null;             String[] receivers = mailInfo.getReceivers();            if (receivers != null){                // 为每个邮件接收者创建一个地址                tos = new InternetAddress[receivers.length + 1];                tos[0] = new InternetAddress(mailInfo.getToAddress());

            }             return false;           }       /**       * 发送邮件给多个接收者,以Html内容       * @param mailInfo    带发送邮件的信息       * @return        */      public static boolean sendMailtoMultiReceiver(MultiMailSenderInfo mailInfo){          MyAuthenticator authenticator = null;

         }          return false;      }            /**       * 发送带抄送的邮件       * @param mailInfo    待发送邮件的消息       * @return        */      public static boolean sendMailtoMultiCC(MultiMailSenderInfo mailInfo){          MyAuthenticator authenticator = null;          if (mailInfo.isValidate()) {              authenticator = new MyAuthenticator(mailInfo.getUserName(),                      mailInfo.getPassword());          }          Session sendMailSession = Session.getInstance(mailInfo                  .getProperties(), authenticator);          try {              Message mailMessage = new MimeMessage(sendMailSession);              // 创建邮件发送者地址              Address from = new InternetAddress(mailInfo.getFromAddress());              mailMessage.setFrom(from);              // 创建邮件的接收者地址,并设置到邮件消息中              Address to = new InternetAddress(mailInfo.getToAddress());              mailMessage.setRecipient(Message.RecipientType.TO, to);                            // 获取抄送者信息              String[] ccs = mailInfo.getCcs();              if (ccs != null){                  // 为每个邮件接收者创建一个地址                  Address[] ccAdresses = new InternetAddress[ccs.length];                  for (int i=0; i<ccs.length; i++){                      ccAdresses[i] = new InternetAddress(ccs[i]);                  }                  // 将抄送者信息设置到邮件信息中,注意类型为Message.RecipientType.CC                  mailMessage.setRecipients(Message.RecipientType.CC, ccAdresses);              }                             mailMessage.setSubject(mailInfo.getSubject());              mailMessage.setSentDate(new Date());              // 设置邮件内容              Multipart mainPart = new MimeMultipart();              BodyPart html = new MimeBodyPart();              html.setContent(mailInfo.getContent(), "text/html; charset=GBK");              mainPart.addBodyPart(html);              mailMessage.setContent(mainPart);              // 发送邮件              Transport.send(mailMessage);              return true;          } catch (MessagingException ex) {              ex.printStackTrace();          }          return false;      }            /**       * 发送多接收者类型邮件的基本信息       */      public static class MultiMailSenderInfo extends MailSenderInfo{          // 邮件的接收者,可以有多个          private String[] receivers;          // 邮件的抄送者,可以有多个          private String[] ccs;                    public String[] getCcs() {              return ccs;          }          public void setCcs(String[] ccs) {              this.ccs = ccs;          }          public String[] getReceivers() {              return receivers;          }          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("xxx@163.com");         mailInfo.setPassword("**********");//您的邮箱密码         mailInfo.setFromAddress("xxx@163.com");         mailInfo.setToAddress("xxx@163.com");         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("xxx@163.com");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>
