夢開始的地方

??? 最近兩天，很巧,又寫delphi的電子郵件客戶端,還寫了Java的電子郵件發送的小程序,一個是工作需要,另一個則是幫朋友的忙,有點巧.

1.Java的電子有件發送程序

SendMailBean.java

package adu.com.kingsoft;

import java.util.Date;
import java.util.Properties;

import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class SendMailBean {

??? private String form;
??? private String to;
??? private String hostName;
??? private String port;
??? private String userName;
??? private String password;
??? private String subject;
??? private String body;
??? public String getBody() {
??????? return body;
??? }
??? public void setBody(String body) {
??????? this.body = body;
??? }
??? public String getSubject() {
??????? return subject;
??? }
??? public void setSubject(String subject) {
??????? this.subject = subject;
??? }
??? public String getForm() {
??????? return form;
??? }
??? public void setForm(String form) {
??????? this.form = form;
??? }
??? public String getHostName() {
??????? return hostName;
??? }
??? public void setHostName(String hostName) {
??????? this.hostName = hostName;
??? }
??? public String getPassword() {
??????? return password;
??? }
??? public void setPassword(String password) {
??????? this.password = password;
??? }
??? public String getPort() {
??????? return port;
??? }
??? public void setPort(String port) {
??????? this.port = port;
??? }
??? public String getTo() {
??????? return to;
??? }
??? public void setTo(String to) {
??????? this.to = to;
??? }
??? public String getUserName() {
??????? return userName;
??? }
??? public void setUserName(String userName) {
??????? this.userName = userName;
??? }

??? public boolean sendMail(){
????????? Properties props=new Properties();
??????? //? props.put("mail.smtp.protocol","smtp");
????????? props.put("mail.smtp.host",hostName);
????????? props.put("mail.smtp.auth","true");
????????? props.put("mail.smpt.port",port);????
????????? Session mailsession=Session.getInstance(props,null); //得到一個發送郵件的會話
?????????
????????? Message msg=new MimeMessage(mailsession);
????????? try{
?????????? msg.setFrom(new InternetAddress(this.getForm()));
?????????? msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse(this.getTo()));
?????????? msg.setSubject(this.getSubject());
?????????? msg.setSentDate(new Date());
?????????? msg.setText(this.getBody());
?????????? Transport transport = mailsession.getTransport("smtp");
?????????? transport.connect(this.getHostName(),this.getUserName(),this.getPassword());
?????????? transport.sendMessage(msg,msg.getRecipients(Message.RecipientType.TO));
????????? // System.out.println("郵件以成功發送到dushengjun@gmail.com");
?????????? transport.close();
?????????? return true;
????????? }catch(Exception e)
????????? {
????????????? System.out.println("產生異常:"+e);
????????????? return false;
????????? }
??? }

}

?

JavaMailApp .java

package adu.com.kingsoft;
import java.util.Date;
import java.util.Properties;
public class JavaMailApp {
???
??? /**
???? * @param args
???? */
??? public static void main(String[] args) {
?????? System.out.println("正在準備發送.....");
?????? SendMailBean smb=new SendMailBean();
?????? smb.setUserName("dushengjun");
?????? smb.setForm("dushengjun@kingsoft.net");
?????? smb.setHostName("mail.kingsoft.net");
?????? smb.setPassword("***************");
?????? smb.setPort("25");
?????? smb.setTo("dushengjun@gmail.com");
?????? smb.setSubject("你好");
?????? smb.setBody("你好 Java");
?????? if(smb.sendMail())
?????? System.out.println("發送成功");
?????? else
?????????? System.out.println("發送失敗");
??? }
}

同時將如下的包加到classpath中:

activation.jar,dsn.jar,imap.jar,mailapi.jar,pop3.jar,smtp.jar

可以測試了,運行一下JavaMailApp 吧

2.Delphi的電子郵件客戶端實現

unit Unit1;

interface

uses
? Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
? Dialogs, StdCtrls, IdBaseComponent, IdComponent, IdTCPConnection,

type
? TForm1 = class(TForm)
??? idSMTP: TIdSMTP;

????? end;??
? end;

procedure TForm1.Button2Click(Sender: TObject);
begin
?if(openDialog1.Execute) then
? begin
?? Edit1.Text:=opendialog1.FileName;
? end;
end;

end.
