javax.mail 调用企业邮箱发送邮件

项目上加的功能，刚做好，亲测，也是吃了个大亏；值得注意的几点：

1、检查smpt、pop3和imap服务是否开启，我用的163免费企业邮箱默认是开启；

2、检查包，不能冲突，再就是javax.mail-xxx.jar,不是那种javax.mail-api-xxx.jar；

3、其他就是验证类一定要加，然后“mail.smtp.auth","true"，默认要设置使用验证。

废话不多说，上代码

第一个类(验证类)

import javax.mail.Authenticator;import javax.mail.PasswordAuthentication;public class MyAuthenticator extends Authenticator{    String userName = null;    String password = null;    public MyAuthenticator() {}    public PasswordAuthentication performCheck(String user, String pass){        userName = user;        password = pass;        return getPasswordAuthentication();    }    protected PasswordAuthentication getPasswordAuthentication(){        return new PasswordAuthentication(userName, password);    }}

第二个类(邮件信息类)

import java.util.Properties;public class MailSenderInfo{    //发送邮件的服务器和端口    private String mailServerHost;    private String mailServerPort = "25";    //发送人的地址    private String fromAddress;    //接受者的地址    private String toAddress;    //登陆邮件发送服务器的用户名和地址    private String userName;    private String passsword;    //是否需要身份验证    private boolean validate;    //邮件主题    private String subject;    //邮件文本内容    private String content;    //邮件附件的文件名    private String[] attachFileNames;    /**     * 配置邮件的会话属性     * */    public Properties getProperties(){        Properties pro = new Properties();        pro.put("mail.smtp.host", this.mailServerHost);        pro.put("mail.smtp.port", this.mailServerPort);        pro.put("mail.smtp.auth", "true");        return pro;    }    public String getMailServerHost() {        return mailServerHost;    }    public void setMailServerHost(String mailServerHost) {        this.mailServerHost = mailServerHost;    }    public String[] getAttachFileNames() {        return attachFileNames;    }    public void setAttachFileNames(String[] attachFileNames) {        this.attachFileNames = attachFileNames;    }    public String getContent() {        return content;    }    public void setContent(String content) {        this.content = content;    }    public String getSubject() {        return subject;    }    public void setSubject(String subject) {        this.subject = subject;    }    public boolean isValidate() {        return validate;    }    public void setValidate(boolean validate) {        this.validate = validate;    }    public String getPasssword() {        return passsword;    }    public void setPasssword(String passsword) {        this.passsword = passsword;    }    public String getUserName() {        return userName;    }    public void setUserName(String userName) {        this.userName = userName;    }    public String getToAddress() {        return toAddress;    }    public void setToAddress(String toAddress) {        this.toAddress = toAddress;    }    public String getFromAddress() {        return fromAddress;    }    public void setFromAddress(String fromAddress) {        this.fromAddress = fromAddress;    }    public String getMailServerPort() {        return mailServerPort;    }    public void setMailServerPort(String mailServerPort) {        this.mailServerPort = mailServerPort;    }}

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

第三个类(邮件发送类)

import javax.mail.*;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;import java.util.Date;import java.util.Properties;public class SimpleMailSender {    public boolean sendTextMail(MailSenderInfo mailInfo){                Properties pro = mailInfo.getProperties();        //需要身份验证，则创建一个密码验证器(认证类)        MyAuthenticator authenticator = new MyAuthenticator();        authenticator.performCheck(mailInfo.getUserName(), mailInfo.getPasssword());        //根据邮件会话属性和密码验证器构造一个发送邮件的session        Session sendMailSession = Session.getInstance(pro, authenticator);

//打印出验证信息        sendMailSession.setDebug(true);        try {            //根据session创建一个邮件消息对象            Message mailMessage = new MimeMessage(sendMailSession);            //创建发送人的地址            Address from = new InternetAddress(mailInfo.getFromAddress());            //设置邮件的发送者到邮件消息对象            mailMessage.setFrom(from);            //创建接收人的地址，并设置到邮件消息对象中            Address to = new InternetAddress(mailInfo.getToAddress());            mailMessage.setRecipient(Message.RecipientType.TO, to);            //设置邮件对象的主题            mailMessage.setSubject(mailInfo.getSubject());            //设置邮件的发送时间            mailMessage.setSentDate(new Date());            //设置邮件的正文            String mailContent = mailInfo.getContent();            mailMessage.setText(mailContent);            //发送邮件            Transport.send(mailMessage);            return true;        }catch (MessagingException ex){            ex.printStackTrace();        }            return false;    }}

-----------------------------------------------------------------------------

测试类

import com.fndsoft.assistor.holiday.util.MailSenderInfo;import com.fndsoft.assistor.holiday.util.SimpleMailSender;public class TestSendEmail {    public static void main(String[] args){        //这个类主要是设置邮件        MailSenderInfo mailInfo = new MailSenderInfo();        mailInfo.setMailServerHost("smtp.qiye.163.com");//注意服务器名称        mailInfo.setMailServerPort("25");        mailInfo.setValidate(true);        mailInfo.setUserName("[e-mail]");        mailInfo.setPasssword("***************");        mailInfo.setFromAddress("[e-mail]");        mailInfo.setToAddress("[e-mail]");        mailInfo.setSubject("验证用户，发送验证码");        mailInfo.setContent("【确认绑定】验证码："+"112233");        //这个类主要来发送邮件        SimpleMailSender sms = new SimpleMailSender();        sms.sendTextMail(mailInfo);    }}

出了那个Authenticator failed，查了很多资料，基本上按上面设置好就没啥大问题了
