Java 发送邮件&发送正文&添加附件

发送邮件案例

1.简单设置发送邮件内容

2.载体设置发送邮件内容

3.载体发送邮件内容+发送附件

 

      public void sendEmailMsg(){

          Properties props = new Properties(); 

          props.put("mail.smtp.host","smtp.exmail.qq.com");//邮件服务器端口

          props.put("mail.smtp.auth","true");  //是否验证用户名和密码正确

          props.put("from_user","from_user"); //发送者

          props.put("pwd","password"); //密码

          props.put("to_user","to_user");//接收者

          Session session = Session.getDefaultInstance(props); //创建session javax.mail.Session

         // 开启debug调试

          session.setDebug(false); 

          try {

             //发送源地址

             InternetAddress fromAddress =new InternetAddress(props.getProperty("from_user")); 

            //发送到地址

             InternetAddress toAddress =new InternetAddress(props.getProperty("to_user")); 

             

             //创建邮件载体

             MimeMessage message =new MimeMessage(session); 

             //设定发件邮箱地址

             message.setFrom(fromAddress); 

             //设定收件邮箱地址

             //RecipientType.TO   -- 收件人

             //RecipientType.CC   -- 抄送人

             //RecipientType.BCC  -- 暗送人[不显示发件人信息]

             message.addRecipient(RecipientType.TO,toAddress);

             message.addHeader("charset","UTF-8");

             message.setSentDate(Calendar.getInstance().getTime());  

             //标题信息  Title

              message.setSubject("标题信息"); 

             

              /****************最简单的内容信息发送************************/

               message.setContent("<div align=\"center\">你好啊</div>","text/html;charset=utf-8");

               Transport transport0 =session.getTransport("smtp"); 

               transport0.connect(props.getProperty("mail.smtp.host"),props.getProperty("from_user"),props.getProperty("pwd"));

               //发送邮件

               transport0.sendMessage(message,message.getAllRecipients()); 

              /****************************************/

           

              //添加正文内容

              /***********直接发送<不含有附件>***************/

              Multipart multipart =new MimeMultipart(); 

              BodyPart contentPart =new MimeBodyPart(); 

              contentPart.setText("Text内容");

              multipart.addBodyPart(contentPart);

              message.setContent(multipart);

            

              Transport transport =session.getTransport("smtp"); 

              transport.connect(props.getProperty("mail.smtp.host"),props.getProperty("from_user"),props.getProperty("pwd")); 

              //发送邮件

              transport.sendMessage(message,message.getAllRecipients()); 

             

              /***********end**************/

             

             

              /***********添加附件&设置正文信息**************/

              //添加附件

              File usFile = new File("filepath"); 

              //添加附件内容

              MimeBodyPart fileBody =new MimeBodyPart(); 

              DataSource source =new FileDataSource(usFile);

              //附件信息添加在载体内容中

              fileBody.setDataHandler(new DataHandler(source));

              fileBody.setText("这里是正文信息..............");

              //处理中文文件名乱码

              fileBody.setFileName(MimeUtility.encodeText(usFile.getName()));

              multipart.addBodyPart(fileBody); 

              message.setContent(multipart); 

              message.setSentDate(new Date()); 

              message.saveChanges();

             

              Transport transport2 =session.getTransport("smtp"); 

              transport2.connect(props.getProperty("mail.smtp.host"),props.getProperty("from_user"),props.getProperty("pwd")); 

              //发送邮件

              transport2.sendMessage(message,message.getAllRecipients()); 

              transport2.close(); 

              /***********end**************/

         

           } catch (Exceptione) {

                 e.printStackTrace();

           }
