android使用javaemail实现发送邮件

使用javaemail实现发送邮件

代码jar包连接

一.导入相关jar包

需要导入activation.jar,additionnal.jar,commons-email.jar和mail.jar这四个jar包

二.创建MailSendInfo实体类

该类封装了邮件的设置信息

import java.util.Properties;     /**      * 邮件的设置信息      * @author Administrator      *      */      public class MailSendInfo {          /**          * 发送邮件的服务器的IP和端口          */          private String mailServerHost;          private String mailServerPort;          /**          * 邮件发送者的地址          */          private String fromAddress;          /**          * 邮件接受者的地址          */          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;          /**          * 邮件发送的主题          */          private String subject;          /**          * 邮件发送的内容          */          private String content;          /**          * 邮件附件的文件名          */          private String[] attachFileNames;            /**          * 获取邮件会话属性          * @return          */          public Properties getProperties(){              Properties p = new Properties();              p.put("mail.smtp.host", this.mailServerHost);              p.put("mail.smtp.port", this.mailServerPort);              p.put("mail.transport.protocol", "smtp");              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 getMailServerPost() {              return mailServerPort;          }          public void setMailServerPost(String mailServerPost) {              this.mailServerPort = mailServerPost;          }          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;          }      }  

三.创建MultiMailSend类

该类封装了具体发送不同类型邮件的方法

import java.io.FileOutputStream;import java.util.ArrayList;import java.util.Date;import java.util.Properties;import javax.activation.DataHandler;import javax.activation.FileDataSource;import javax.mail.Address;import javax.mail.Message;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;import javax.mail.internet.MimeUtility;import android.os.Environment;import android.util.Log;public class MultiMailSend {    private MailSendInfo info;      private String path;      public MultiMailSend(String path){          this.path = path;      }      /**      * 以文本格式发送邮件      * @param info 待发送的邮件信息      * @return      */      public void sendTextMail(MailSendInfo info){          this.info = info;          //判断是否需要身份验证          Properties properties = info.getProperties();          //1、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(properties);          //开启Session的debug模式，这样就可以查看到程序发送Email的运行状态          sendMailSession.setDebug(true);          try {              //2、通过session得到transport对象,以便连接邮箱并发送                Transport transport = sendMailSession.getTransport();                //3、使用邮箱的用户名和密码连上邮件服务器，发送邮件时，发件人需要提交邮箱的用户名和密码给SMTP服务器，用户名和密码都通过验证之后才能够正常发送邮件给收件人。              transport.connect("smtp.163.net", "[e-mail]", "");            //4、创建邮件消息              Message mailMessage = createSimpleMail(sendMailSession);              //5、发送邮件消息              transport.sendMessage(mailMessage, mailMessage.getAllRecipients());              transport.close();          } catch (Exception e) {              e.printStackTrace();          }      }      /**      * 发送内容带有图片的邮件      */      public void sendImageEmail(MailSendInfo info){          this.info = info;          Properties properties = info.getProperties();          //1、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(properties);          //开启Session的debug模式，这样就可以查看到程序发送Email的运行状态          sendMailSession.setDebug(true);          try {              //2、通过session得到transport对象,以便连接邮箱并发送                Transport transport = sendMailSession.getTransport();                //3、使用邮箱的用户名和密码连上邮件服务器，发送邮件时，发件人需要提交邮箱的用户名和密码给SMTP服务器，用户名和密码都通过验证之后才能够正常发送邮件给收件人。              transport.connect("smtp.163.net", "[e-mail]", "");            //4、创建邮件消息              Message mailMessage = createImageMail(sendMailSession);              //5、发送邮件消息              transport.sendMessage(mailMessage, mailMessage.getAllRecipients());              transport.close();          } catch (Exception e) {              e.printStackTrace();          }      }      /**      * 发送带有附件的邮件      * @param info      */      public void sendAttachment(MailSendInfo info,ArrayList<String> list){          this.info = info;          Properties properties = info.getProperties();          //1、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(properties);          //开启Session的debug模式，这样就可以查看到程序发送Email的运行状态          sendMailSession.setDebug(true);          try {              //2、通过session得到transport对象,以便连接邮箱并发送                Transport transport = sendMailSession.getTransport();                //3、使用邮箱的用户名和密码连上邮件服务器，发送邮件时，发件人需要提交邮箱的用户名和密码给SMTP服务器，用户名和密码都通过验证之后才能够正常发送邮件给收件人。               transport.connect("smtp.163.net", "[e-mail]", "");            //4、创建邮件消息              Message mailMessage = createAttachmentMail(sendMailSession,list);              //5、发送邮件消息              transport.sendMessage(mailMessage, mailMessage.getAllRecipients());              transport.close();          } catch (Exception e) {              e.printStackTrace();          }      }      /**      * 发送复杂邮件      * @param info      */      public void sendMixedMail(MailSendInfo info,ArrayList<String> list){          this.info = info;          Properties properties = info.getProperties();          //1、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(properties);          //开启Session的debug模式，这样就可以查看到程序发送Email的运行状态          sendMailSession.setDebug(true);          try {              //2、通过session得到transport对象,以便连接邮箱并发送                Transport transport = sendMailSession.getTransport();                //3、使用邮箱的用户名和密码连上邮件服务器，发送邮件时，发件人需要提交邮箱的用户名和密码给SMTP服务器，用户名和密码都通过验证之后才能够正常发送邮件给收件人。              transport.connect("smtp.163.net", "[e-mail]", "");            //4、创建邮件消息              Message mailMessage = createMixedMail(sendMailSession,list);              //5、发送邮件消息              transport.sendMessage(mailMessage, mailMessage.getAllRecipients());

             //设置邮件消息的发送者              mailMessage.setFrom(from);            //创建邮件的接受者地址，并设置到邮件消息中              Address[] to = new InternetAddress[info.getToAddress().length];            for(int i =0; i < info.getToAddress().length ; i++) {                to[i] = new InternetAddress(info.getToAddress()[i]);            }            //设置邮件消息的接受者, Message.RecipientType.TO属性表示接收者的类型为TO               mailMessage.setRecipients(Message.RecipientType.TO, to);              //设置邮件标题              mailMessage.setSubject(info.getSubject());              //设置邮件内容              mailMessage.setText(info.getContent());              //设置邮件发送的时间              mailMessage.setSentDate(new Date());          } catch (Exception e) {              Log.e("TAG", "邮件消息创建失败");              e.printStackTrace();          }          return mailMessage;      }  }

四.创建EmailUtils类

该类封装了发送邮件时的设置，调用MultiMailSend的方法实现发送功能

import java.util.ArrayList;public class EmailUtils {     private String port = "25";  //smtp协议使用的是25号端口          private String server; // 发件人邮件服务器          private String user;   // 使用者账号          private String password; //使用者密码          private String[] emailReciver;//收件人        private ArrayList<String> filenames = new ArrayList<String>();//附件名        private String path;    //附件路径        private String title;   //邮件标题        private String einfo;   //邮件内容        //构造发送邮件帐户的服务器，端口，帐户，密码，接收人数组，附件路径，附件名，邮件标题，邮件内容          public EmailUtils(String server,                 String port,                 String user,                 String passwd,                String[] emailReciver,                String path,                ArrayList<String> filenames,                String title,                String einfo                    ) {              this.port = port;              this.user = user;              this.password = passwd;              this.server = server;            this.emailReciver = emailReciver;            this.filenames = filenames;            this.path = path;            this.title = title;            this.einfo = einfo;        }        //通过JavaMail发送文件          public void sendCSVFilByJavaMail() {              //先设置邮件              MailSendInfo info = new MailSendInfo();  //          info.setMailServerHost("smtp.163.com");              info.setMailServerHost(server);            info.setMailServerPost(port);              info.setValidate(true);              info.setUserName(user);              info.setPassWord(password);//邮箱密码              info.setFromAddress("[e-mail]");              //以下三个内容是需要修改的              info.setToAddress(emailReciver);              info.setSubject(title);              info.setContent(einfo);              MultiMailSend senMail = new MultiMailSend(path);//这个类用来发送邮件              senMail.sendAttachment(info,filenames);          }  }

五.具体使用

//发送邮件        new Thread(){              public void run() {                  ArrayList<String> filename = new ArrayList<String>();                filename.add(log);                EmailUtils emailUtils = new EmailUtils(SERVICE,                        PORT,                        USER,                        PASSWORD,                        RECIVER,                        logFilePath+"/",                        filename,                        getString(R.string.emailtitle)+ MyDate.getDateEN(),                        emailinfo);                emailUtils.sendCSVFilByJavaMail();              };          }.start();
