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工具，具体步骤如如下： 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。

java编写邮件收发程序步骤

补充回答：如果不涉及到MIME，只是收发简单文本邮件。

就会比较简单。

因为就像你说的，smtp和pop3协议就是文本格式的。

你用Socket建立连接后，就像读文件一样，一行一行的读数据，然后按照协议分析数据格式。

例如如果开始时USER那么后面可能跟的就是用户等。

就是一个字符串解析和匹配的过程。

网上好像有这类代码，自己找一个学习一下。

我以前用C在68k上作过，不是很难。

不过代码已经没有了。

你的是邮件客户端，功能类似于outlook,foxmail等，如果你能上网，就不需要邮件服务器，直接用自己的邮件账号来测试，例如如果你有一个sina的邮件账户，就可以从sina服务器收发邮件。

不过为了测试方便，还是上网去收一个邮件服务器把。

例如foxmail server等。

网上有教程，可以配置好的。

对于编程，既然要求用socket编写，那么就要熟悉java的socket编程，这部分倒是很简单。

可能还需要看看多线程部分。

另外，你需要学习一下， smtp和pop3这两个网络协议的内容，因为你需要解析这两个协议。

如果需要收发代附件的，还需要看mime的内容，不过估计不需要。

其实java有自己的类库javamail，可以实现手法邮件，功能很强大。

不过既然要求必须用socket，那就不能这个了。

说的太罗嗦了。

总结一下： 1）配置邮件服务器，搭建测试环境 2）熟悉java的socket编程、 Swing编程（编写界面）、多线程（选用） 3）熟悉smtp和pop3的内容（内容很多，了解基本的就可以） 网上应该有类似代码，可以用来参考。

java实现发送邮件功能

要实现邮件发送功能需要导入包：mail.jar /* * Generated by MyEclipse Struts * Template path: templates/java/JavaClass.vtl */ .demo.action; import java.util.Properties; import javax.mail.Message; import javax.mail.Session; import javax.mail.Transport; import Address; import .MimeMessage; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; .apache.struts.action.Action; .apache.struts.action.ActionForm; .apache.struts.action.ActionForward; .apache.struts.action.ActionMapping; .demo.form.DemoForm; public class DemoAction extends Action { private static final String CONTENT_TYPE = "test/html;charset=GB2312"; public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) { DemoForm demoForm = (DemoForm) form; System.out.println("标题是" + demoForm.getBiaoti()); System.out.println("内容是" + demoForm.getNeirong()); try { response.setContentType(CONTENT_TYPE); String smtphost = ""; // 发送邮件服务器 String user = "q0000015369"; // 邮件服务器登录用户名 String password = "Queshuwen26"; // 邮件服务器登录密码 String from = "q0000015369@"; // String to = "c0000016205@"; // 收件人邮件地址 String subject = demoForm.getBiaoti(); // 邮件标题 String body = demoForm.getNeirong(); // 邮件内容 Properties props = new Properties(); props.put("mail.smtp.host", smtphost); props.put("mail.smtp.auth", "true"); Session ssn = Session.getInstance(props, null); MimeMessage message = new MimeMessage(ssn); Address fromAddress = new Address(from); message.setFrom(fromAddress); Address toAddress = new Address(to); message.addRecipient(Message.RecipientType.TO, toAddress); message.setSubject(subject); message.setText(body); Transport transport = ssn.getTransport("smtp"); transport.connect(smtphost, user, password); transport.sendMessage(message, message .getRecipients(Message.RecipientType.TO)); // transport.send(message); transport.close(); return mapping.findForward(""); } catch (Exception e) { e.printStackTrace(); return mapping.findForward("fail"); } } }

怎么用JAVA实现邮件发送

一个小例子，也可使用其他api import?java.util.Properties; import?javax.mail.Address; import?javax.mail.Authenticator; import?javax.mail.BodyPart; import?javax.mail.Message; import?javax.mail.Multipart; import?javax.mail.PasswordAuthentication; import?javax.mail.Session; import?javax.mail.Transport; import?Address; import?.MimeBodyPart; import?.MimeMessage; import?.MimeMultipart; import?.MimeUtility; public?class?Test?{ //?test public?static?void?main(String[]?args)?throws?Exception?{ sendEmail("",?"测试",?"测试",?"！！！收件人地址！！！",?"！！！发件人邮箱用户名！！！",?"！！！邮箱密码！！！",?"发件人昵称"); } /** ?*? ?*?@param?smtp ?*?@throws?Exception? ?*/ public?static?void?sendEmail(String?emailServer,?String?subject,?String?mailBody,?String?receiver,?final?String?username,?final?String?password,?String?nickname)?throws?Exception?{ Properties?props?=?new?Properties(); props.put("mail.smtp.auth",?"true"); props.setProperty("mail.transport.protocol",?"smtp"); props.setProperty("mail.smtp.host",?emailServer); props.setProperty("mail.smtp.socketFactory.class",?".ssl.SSLSocketFactory"); props.setProperty("mail.smtp.socketFactory.fallback",?"false"); props.setProperty("mail.smtp.port",?"465"); props.setProperty("mail.smtp.socketFactory.port",?"465"); Session?session?=?Session.getDefaultInstance(props,?new?Authenticator()?{ protected?PasswordAuthentication?getPasswordAuthentication()?{ return?new?PasswordAuthentication(username,?password); } }); session.setDebug(true); MimeMessage?mimeMsg?=?new?MimeMessage(session); Multipart?mp?=?new?MimeMultipart(); mimeMsg.setSubject(MimeUtility.encodeText(subject,?"utf-8",?null)); nickname?=?MimeUtility.encodeText(nickname,?"utf-8",?null); mimeMsg.setFrom(new?Address(username,?nickname,?"UTF-8")); BodyPart?bp?=?new?MimeBodyPart(); bp.setContent(mailBody,?"text/html;charset=utf-8"); mp.addBodyPart(bp); mimeMsg.setRecipients(Message.RecipientType.TO,?Address.parse(receiver)); mimeMsg.setContent(mp); mimeMsg.saveChanges(); Transport?transport?=?session.getTransport(); transport.connect(username,?password); Address[]?allRecipients?=?mimeMsg.getAllRecipients(); transport.sendMessage(mimeMsg,?allRecipients); transport.close(); } }

java 发送邮件 需要哪些jar包

使用JavaMail发送邮件需要用到mail.jar和activtion.jar两个包。

该类实现了较完整的邮件发送功能，包括以HTML格式发送，添加附件和抄送人。

下面是具体的代码： .cgw.util.mail;?? import?java.util.Properties;?? import?javax.activation.DataHandler;?? import?javax.activation.FileDataSource;?? import?javax.mail.Address;?? import?javax.mail.BodyPart;?? import?javax.mail.Message;??

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@"; public static final String mailCount ="用户名"; public static final String mailPassword ="密码"; public static final String mailServer =""; //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 Address; import .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='>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 Address from= new Address(str_from); //pukeyouxintest2@ 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 Address to=new Address(str_to); //pukeyouxintest3@ 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
