java邮件

㈠ java发邮件的几种方式

下面给你介绍3种发送邮件的方式：

1：使用JavaMail发送邮件

㈡ Java发送邮件

本地要 有smtp服务器，才可以测试 。。。。。。。。。。。。。~

~~~~~~~~~~~~~~~~~~~~~~~~

㈢ javamail如何判断邮件状态

pop3服务器是不支持此做法的,
你用Foxmail收邮件(保留备份在服务器上),然后再用邮件服务器自带的web收邮件,最后用OE收邮件,
我以前处理这一问题的做法供你参考参考:
收邮件时把邮件的唯一的UID字符串取出,并保存到web服务器的一个文本文件中,
这样就可以实现通过判断pop3服务器上的每一邮件的UID
是否已存在于文本文件中来确定是否为新邮件了.

㈣ java 代码发邮件怎么添加附件

实现java发送邮件的过程大体有以下几步：

准备一个properties文件，该文件中存放SMTP服务器地址等参数。

利用properties创建一个Session对象

利用Session创建Message对象，然后设置邮件主题和正文

利用Transport对象发送邮件

需要的jar有2个：activation.jar和mail.jar发送附件，需要用到Multipart对象。

importjava.io.IOException;

this.sender_password=properties.getProperty("mail.sender.password");
}catch(IOExceptione){
e.printStackTrace();
}

session=Session.getInstance(properties);
session.setDebug(debug);//开启后有调试信息
message=newMimeMessage(session);
}

㈤ 怎样用java实现邮件的发送

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.Socket;
import java.net.SocketException;

} catch (SocketException e) {

} catch (Exception e) {

} finally {
//System.out.println("已经建立连接!");
}

}

// 注册到邮件服务器
public void helo(String server, BufferedReader in, BufferedWriter out)
throws IOException {
int result;
result = getResult(in);
// 连接上邮件服务后,服务器给出220应答
if (result != 220) {
throw new IOException("连接服务器失败");
}
result = sendServer("HELO " + server, in, out);
// HELO命令成功后返回250
if (result != 250) {
throw new IOException("注册邮件服务器失败！");
}
}

private int sendServer(String str, BufferedReader in, BufferedWriter out)
throws IOException {

}

String line = "";
try {

/*
if (debug) {

}
*/
} catch (Exception e) {
e.printStackTrace();
}
// 从服务器返回消息中读出状态码,将其转换成整数返回

StringTokenizer st = new StringTokenizer(line, " ");

}

public void authLogin(MailMessage message, BufferedReader in,

result = sendServer("AUTH LOGIN", in, out);

if (result != 334) {

}

if (result != 235) {
throw new IOException("验证失败！");
}
}

// 开始发送消息，邮件源地址
public void mailfrom(String source, BufferedReader in, BufferedWriter out)
throws IOException {
int result;
result = sendServer("MAIL FROM:<" + source + ">", in, out);
if (result != 250) {
throw new IOException("指定源地址错误");
}
}

// 设置邮件收件人
public void rcpt(String touchman, BufferedReader in, BufferedWriter out)
throws IOException {
int result;
result = sendServer("RCPT TO:<" + touchman + ">", in, out);
if (result != 250) {
throw new IOException("指定目的地址错误！");
}
}

// 邮件体
public void data(String from, String to, String subject, String content,
BufferedReader in, BufferedWriter out) throws IOException {
int result;
result = sendServer("DATA", in, out);
// 输入DATA回车后,若收到354应答后,继续输入邮件内容
if (result != 354) {
throw new IOException("不能发送数据");
}
out.write("From: " + from);
out.newLine();
out.write("To: " + to);
out.newLine();
out.write("Subject: " + subject);
out.newLine();
out.newLine();
out.write(content);
out.newLine();
// 句号加回车结束邮件内容输入
result = sendServer(".", in, out);
//System.out.println(result);
if (result != 250) {
throw new IOException("发送数据错误");
}
}

// 退出
public void quit(BufferedReader in, BufferedWriter out) throws IOException {
int result;
result = sendServer("QUIT", in, out);
if (result != 221) {
throw new IOException("未能正确退出");
}
}

// 发送邮件主程序
public boolean sendMail(MailMessage message, String server) {
try {
BufferedReader in = new BufferedReader(new InputStreamReader(
socket.getInputStream()));
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(
socket.getOutputStream()));
helo(server, in, out);// HELO命令
authLogin(message, in, out);// AUTH LOGIN命令
mailfrom(message.getFrom(), in, out);// MAIL FROM
rcpt(message.getTo(), in, out);// RCPT
data(message.getDatafrom(), message.getDatato(),
message.getSubject(), message.getContent(), in, out);// DATA
quit(in, out);// QUIT
} catch (Exception e) {
e.printStackTrace();
return false;

}
return true;
}
}
再写一个MailMessage.java，set/get方法即可。

㈧ java 发送邮件

要两个java文件 还有一个mail.jar是不是只能用javamail谁也不敢说

第一个：

public class Constant {

public static final String mailAddress ="用户名@163.com";
public static final String mailCount ="用户名";
public static final String mailPassword ="密码";
public static final String mailServer ="smtp.163.com";
//pukeyouxintest,

}

第二个：

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 SendMail {
/**
* 发送简单邮件
* @param str_from：发件人地址
* @param str_to:收件人地址
* @param str_title：邮件标题
* @param str_content：邮件正文
*/
public static void send(String str_from,String str_to,String str_title,String str_content) {

// str_content="<a href='www.163.com'>html元素</a>"; //for testing send html mail!

try {
//建立邮件会话
Properties props=new Properties(); //用来在一个文件中存储键-值对的，其中键和值是用等号分隔的，
//存储发送邮件服务器的信息
props.put("mail.smtp.host",Constant.mailServer);
//同时通过验证
props.put("mail.smtp.auth","true");
//根据属性新建一个邮件会话
Session s=Session.getInstance(props);
s.setDebug(true); //有他会打印一些调试信息。

//由邮件会话新建一个消息对象
MimeMessage message=new MimeMessage(s);

//设置邮件
InternetAddress from= new InternetAddress(str_from); //[email protected]
message.setFrom(from); //设置发件人的地址
//
// //设置收件人,并设置其接收类型为TO
InternetAddress to=new InternetAddress(str_to); //[email protected]
message.setRecipient(Message.RecipientType.TO, to);

//设置标题
message.setSubject(str_title); //java学习

//设置信件内容
// message.setText(str_content); //发送文本邮件 //你好吗？
message.setContent(str_content, "text/html;charset=gbk"); //发送HTML邮件 //<b>你好</b><br><p>大家好</p>
//设置发信时间
message.setSentDate(new Date());

//存储邮件信息
message.saveChanges();

//发送邮件
Transport transport=s.getTransport("smtp");
//以smtp方式登录邮箱,第一个参数是发送邮件用的邮件服务器SMTP地址,第二个参数为用户名,第三个参数为密码
transport.connect(Constant.mailServer,Constant.mailCount,Constant.mailPassword);
//发送邮件,其中第二个参数是所有已设好的收件人地址
transport.sendMessage(message,message.getAllRecipients());
transport.close();

} catch (Exception e) {
e.printStackTrace();
}
}

public static void main(String[] args) {
//测试用的，你吧你想写的内容写上去就行
send(Constant.mailAddress,"收件人邮箱","标题","<b>内容</b>");
}
}

然后把mail.jar导入，就可以了，我用的是163 的，其他的吧相应的服务器改一下就行了

注意点：1 jar可能有冲突，如果是demo可以直接应用mail.jar

如果是一个工程则要替换javaEE中的mail.jar包

2 关于properties配置文件的地址问题

Class.getResourceAsStream(String path) ： path 不以’/'开头时默认是从此类所在的包下取资源，以’/'开头则是从

ClassPath根下获取。其只是通过path构造一个绝对路径，最终还是由ClassLoader获取资源。
