『伍』 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
『陆』 如何使用Java发送qq邮件
方法:
1.前提准备工作：
首先，邮件的发送方要开启POP3 和SMTP服务--即发送qq邮件的账号要开启POP3 和SMTP服务
2.开启方法：
登陆qq邮箱
3.点击 设置
4.点击—-账户
5.找到：POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务 —点击开启
6.送短信 —–点击确定
7.稍等一会，很得到一个授权码！ –注意：这个一定要记住，一会用到
8.点击保存修改 —OK 完成
9.java 测试代码：
package cn.cupcat.test;
import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMessage.RecipientType;
public class SendmailUtil {
public static void main(String[] args) throws AddressException, MessagingException {
Properties properties = new Properties();
properties.put("mail.transport.protocol", "smtp");// 连接协议
properties.put("mail.smtp.host", "smtp.qq.com");// 主机名
properties.put("mail.smtp.port", 465);// 端口号
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.ssl.enable", "true");//设置是否使用ssl安全连接 ---一般都使用
properties.put("mail.debug", "true");//设置是否显示debug信息 true 会在控制台显示相关信息
//得到回话对象
Session session = Session.getInstance(properties);
// 获取邮件对象
Message message = new MimeMessage(session);
//设置发件人邮箱地址
message.setFrom(new InternetAddress("[email protected]"));
//设置收件人地址 message.setRecipients( RecipientType.TO, new InternetAddress[] { new InternetAddress("[email protected]") });
//设置邮件标题
message.setSubject("这是第一封Java邮件");
//设置邮件内容
message.setText("内容为： 这是第一封java发送来的邮件。");
//得到邮差对象
Transport transport = session.getTransport();
//连接自己的邮箱账户
transport.connect("[email protected]", "vvctybgbvvophjcj");//密码为刚才得到的授权码
//发送邮件 transport.sendMessage(message, message.getAllRecipients());
}
}
10.运行就会发出邮件了。。。。
下面是我收到邮件的截图，当然我把源码中的邮件地址都是修改了，不是真实的，你们测试的时候，可以修改能你们自己的邮箱。最后，祝你也能成功，如果有什么问题，可以一起讨论！
注意事项
得到的授权码一定要保存好，程序中要使用

import org.apache.commons.mail.EmailException; import org.apache.commons.mail.HtmlEmail; public class Mail { public static void main(String[] args) { //SimpleEmail email = new SimpleEmail(); HtmlEmail email = new HtmlEmail(); email.setHostName("smtp.163.com");//邮件服务器 email.setAuthentication("xingui5624", "******");//smtp认证的用户名和密码 try { email.addTo("[email protected]");//收信者 email.setFrom("[email protected]", "******");//发信者 email.setSubject("xingui5624的测试邮件");//标题 email.setCharset("UTF-8");//编码格式 email.setMsg("这是一封xingui5624的测试邮件");//内容 email.send();//发送 System.out.println("send ok.........."); } catch (EmailException e) { e.printStackTrace(); } } } 【如果发送不成功，可能是你的jar包问题，javamail 的jar可能和jdk1.5以上的j2ee的jar冲突。还有就是可能你的邮箱不支持pop3和smtp协议。】

『玖』 java中如何实现公司邮箱发送邮件配置
Java中可以通过Javamail API实现公司邮箱邮件发送配置，Java mail是利用现有的邮箱账户发送邮件的版工具，具体步权骤如如下：
1、通过JavamailAPI设置发送者邮箱用户名及密码
2、通过JavamailAPI设置邮件主题、邮件内容、附件及邮件发送时间
3、通过JavamailAPI设置发送者邮箱地址及接收者邮箱地址，接收者地址可以是多个及抄送
4、邮件的需基本元素都设置完毕后，即可通过Javamail API的发送接口执行发送操作。
