期末操作系统

2010JavaEE课程设计个人系统开发报告项目名称：邮件系统报告人：赵孟浩学号：20087611046指导老师：李伦1 用户登录：用户输入密码及验证信息即可进入邮件客户端，并可以查看自己邮箱的基本信息。

2 发送邮件：发送邮件格式有普通邮件，html格式的邮件，带有附件的邮件等。

3 接收邮件：登录客户端就自动接收邮件。

我参与的内容是发送邮件，主要集中在sendMailBean.java和useSendBean中。

1 sendMailBean.java1. public void sended()throws Exception{StringBuffer sb=new StringBuffer();String string="send";BufferedWriter bw=new BufferedWriter(new FileWriter("e:\\"+string+name,true));sb.append("主题:"+subject+" ");sb.append("发件人:"+from+" ");sb.append("收件人:"+to+" ");bw.write(sb.toString());bw.newLine();bw.flush();}主要是用来传送用户输入的信息2. public void init(){host="127.0.0.1";props=System.getProperties();props.put("mail.smtp.host",host);sendMailSession=Session.getDefaultInstance(props,null);message = new MimeMessage(sendMailSession);if (to != null) {try {message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to));} catch (MessagingException ex) {Logger.getLogger(SendMailBean.class.getName()).log(Level.SEVERE, null, ex);}}if (cc != null) {try {message.setRecipients(, InternetAddress.parse(cc));} catch (MessagingException ex) {Logger.getLogger(SendMailBean.class.getName()).log(Level.SEVERE,}}if (bcc != null) {try {message.setRecipients(Message.RecipientType.BCC, InternetAddress.parse(bcc));} catch (MessagingException ex) {Logger.getLogger(SendMailBean.class.getName()).log(Level.SEVERE, null, ex);}}}部署邮件系统主机的各个属性3.. public void send(String type) throws UnsupportedEncodingException {init();int n = 0;if (type.matches("html")) {n = 1;} else if (type.matches("plain")) {n = 2;} else if (type.matches("multipart")) {n = 3;}switch (n) {case 0:System.out.println("pattern not match");break;case 1:sendHtml();break;case 2:sendPlain();break;case 3:sendMultipart();break;}}选择发送邮件的类型4. public void sendPlain() {try {message.setFrom(new InternetAddress(from));message.setRecipient(Message.RecipientType.TO, new InternetAddress(to));message.setSubject(subject);message.setSentDate(new Date());message.setText(body);Transport.send(message);} catch (MessagingException e) {System.out.println(e.toString());}}发送普通的邮件5 public void sendHtml() {try {message.setFrom(new InternetAddress(from));message.setSubject(subject);message.setDataHandler(new javax.activation.DataHandler(body, "text/html;charset=utf-8"));Transport.send(message);} catch (Exception e) {System.out.println(e.toString());}}发送html类型的邮件6. public void sendMultipart() {try {message.setFrom(new InternetAddress(from));message.setRecipient(Message.RecipientType.TO, new InternetAddress(to));message.setSubject(subject);BodyPart messageBodyPart = new MimeBodyPart();messageBodyPart.setText(body);Multipart multipart = new MimeMultipart();multipart.addBodyPart(messageBodyPart);messageBodyPart = new MimeBodyPart();System.out.println(filename);DataSource source = new FileDataSource(filename);messageBodyPart.setDataHandler(new DataHandler(source));messageBodyPart.setFileName(filename);multipart.addBodyPart(messageBodyPart);message.setContent(multipart);Transport.send(message);} catch (MessagingException e) {System.out.println(e.toString());}}发送带有附件的邮件public SendMailBean() {}/*** @return the from*/public String getFrom() {return from;}/*** @param from the from to set*/public void setFrom(String from) {this.from = from;}/*** @return the from*//*** @return the filename*/public String getFilename() {return filename;}/*** @param filename the filename to set*/public void setFilename(String filename) { this.filename = filename;}public String getBody() {return body;}/*** @param from the from to set*/public void setBody(String body) { this.body = body;}/*** @return the to*/public String getTo() {return to;}/*** @param to the to to set*/public void setTo(String to) {this.to = to;}/*** @return the subject*/public String getSubject() {return subject;}/*** @param subject the subject to set */public void setSubject(String subject) { this.subject = subject;}/*** @return the cc*/public String getCc() {return cc;}/*** @param cc the cc to set*/public void setCc(String cc) { = cc;}/*** @return the bcc*/public String getBcc() {return bcc;}/*** @param bcc the bcc to set*/public void setBcc(String bcc) {this.bcc = bcc;}/*** @return the host*/public String getHost() {return host;}/*** @param host the host to set*/public void setHost(String host) {this.host = host;}传送邮件的参数eSendBean.jsp<html><head><meta http-equiv="Content-Type" content="text/html;
