java maven 發送郵件

1,先導入一個jar包 html

      在pom.xml 中寫入java

      <!-- 郵件start -->
      <dependency>
      <groupId>javax.mail</groupId>
      <artifactId>mail</artifactId>
      <version>1.4.7</version>
      </dependency>
      <!-- 郵件end -->服務器

2,寫一個郵件的類包括,發送內容,端口等session

 


public class MailSenderInfo {
 
     // 發送郵件的服務器的IP和端口    
     private String mailServerHost;    
     private String mailServerPort = "25";    
     // 郵件發送者的地址    
     private String fromAddress;    
     // 郵件接收者的地址    
     private String toAddress;    
     // 登錄郵件發送服務器的用戶名和密碼    
     private String userName;    
     private String password;    
     // 是否須要身份驗證    
     private boolean validate = false;    
     // 郵件主題    
     private String subject;    
     // 郵件的文本內容    
     private String content;    
     // 郵件附件的文件名    
     private String[] attachFileNames;   
     
     private String iwallHost ;
     /**   
       * 得到郵件會話屬性   
       */    
     public Properties getProperties(){    
       Properties p = new Properties();    
       p.put("mail.smtp.host", this.mailServerHost);    
       p.put("mail.smtp.port", this.mailServerPort);    
       p.put("mail.smtp.auth", validate ? "true" : "false");    
       return p;    
     }    
     public String getMailServerHost() {    
       return mailServerHost;    
     }    
     public void setMailServerHost(String mailServerHost) {    
       this.mailServerHost = mailServerHost;    
     }   
     public String getMailServerPort() {    
       return mailServerPort;    
     }   
     public void setMailServerPort(String mailServerPort) {    
       this.mailServerPort = mailServerPort;    
     }   
     public boolean isValidate() {    
       return validate;    
     }   
     public void setValidate(boolean validate) {    
       this.validate = validate;    
     }   
     public String[] getAttachFileNames() {    
       return attachFileNames;    
     }   
     public void setAttachFileNames(String[] fileNames) {    
       this.attachFileNames = fileNames;    
     }   
     public String getFromAddress() {    
       return fromAddress;    
     }    
     public void setFromAddress(String fromAddress) {    
       this.fromAddress = fromAddress;    
     }   
     public String getPassword() {    
       return password;    
     }   
     public void setPassword(String password) {    
       this.password = password;    
     }   
     public String getToAddress() {    
       return toAddress;    
     }    
     public void setToAddress(String toAddress) {    
       this.toAddress = toAddress;    
     }    
     public String getUserName() {    
       return userName;    
     }   
     public void setUserName(String userName) {    
       this.userName = userName;    
     }   
     public String getSubject() {    
       return subject;    
     }   
     public void setSubject(String subject) {    
       this.subject = subject;    
     }   
     public String getContent() {    
       return content;    
     }   
     public void setContent(String textContent) {    
       this.content = textContent;    
     }
  public String getIwallHost() {
   return iwallHost;
  }
  public void setIwallHost(String iwallHost) {
   this.iwallHost = iwallHost;
  }   
 }  ide

 

3,爲了可配置性,可將上面的類的所需信息寫入配置文件裏this

<bean id = "mailInfo" class = "xxxxxxx.MailSenderInfo" >
  <property name="mailServerHost" value = "smtp.exmail.qq.com"></property>
  <property name="mailServerPort" value = "25"></property>
  <property name="fromAddress" value = "xxxxxxx@xx.xxx"></property>
  <property name="userName" value = "xxxxxxxx"></property>
  <property name="password" value = "xxxxx"></property>
  <property name="iwallHost" value = "http://localhost:8080/xxxxx"></property>
 </bean>.net

 

4,寫一個簡單的發送郵件的類,包含發送text或者 html的方法線程


public class SimpleMailSender  {    
/**   
  * 以文本格式發送郵件   
  * @param mailInfo 待發送的郵件的信息   
  */    
    public boolean sendTextMail(MailSenderInfo mailInfo) {    
      // 判斷是否須要身份認證    
      MyMailAuthenticator authenticator = null;    
      Properties pro = mailInfo.getProperties();   
      if (mailInfo.isValidate()) {    
      // 若是須要身份認證,則建立一個密碼驗證器    
        authenticator = new MyMailAuthenticator(mailInfo.getUserName(), mailInfo.getPassword());    
      }   
      // 根據郵件會話屬性和密碼驗證器構造一個發送郵件的session    
      Session sendMailSession = Session.getDefaultInstance(pro,authenticator);    
      try {    
      // 根據session建立一個郵件消息    
      Message mailMessage = new MimeMessage(sendMailSession);    
      // 建立郵件發送者地址    
      Address from = new InternetAddress(mailInfo.getFromAddress());    
      // 設置郵件消息的發送者    
      mailMessage.setFrom(from);    
      // 建立郵件的接收者地址,並設置到郵件消息中    
      Address to = new InternetAddress(mailInfo.getToAddress());    
      mailMessage.setRecipient(Message.RecipientType.TO,to);    
      // 設置郵件消息的主題    
      mailMessage.setSubject(mailInfo.getSubject());    
      // 設置郵件消息發送的時間    
      mailMessage.setSentDate(new Date());    
      // 設置郵件消息的主要內容    
      String mailContent = mailInfo.getContent();    
      mailMessage.setText(mailContent);    
      // 發送郵件    
      Transport.send(mailMessage);   
      return true;    
      } catch (MessagingException ex) {    
          ex.printStackTrace();    
      }    
      return false;    
    }    
       
    /**   
      * 以HTML格式發送郵件   
      * @param mailInfo 待發送的郵件信息   
      */    
    public static boolean sendHtmlMail(MailSenderInfo mailInfo){    
      // 判斷是否須要身份認證    
      MyMailAuthenticator authenticator = null;   
      Properties pro = mailInfo.getProperties();   
      //若是須要身份認證,則建立一個密碼驗證器     
      if (mailInfo.isValidate()) {    
        authenticator = new MyMailAuthenticator(mailInfo.getUserName(), mailInfo.getPassword());   
      }    
      // 根據郵件會話屬性和密碼驗證器構造一個發送郵件的session    
      Session sendMailSession = Session.getDefaultInstance(pro,authenticator);    
      try {    
      // 根據session建立一個郵件消息    
      Message mailMessage = new MimeMessage(sendMailSession);    
      // 建立郵件發送者地址    
      Address from = new InternetAddress(mailInfo.getFromAddress());    
      // 設置郵件消息的發送者    
      mailMessage.setFrom(from);    
      // 建立郵件的接收者地址,並設置到郵件消息中    
      Address to = new InternetAddress(mailInfo.getToAddress());    
      // Message.RecipientType.TO屬性表示接收者的類型爲TO    
      mailMessage.setRecipient(Message.RecipientType.TO,to);    
      // 設置郵件消息的主題    
      mailMessage.setSubject(mailInfo.getSubject());    
      // 設置郵件消息發送的時間    
      mailMessage.setSentDate(new Date());    
      // MiniMultipart類是一個容器類,包含MimeBodyPart類型的對象    
      Multipart mainPart = new MimeMultipart();    
      // 建立一個包含HTML內容的MimeBodyPart    
      BodyPart html = new MimeBodyPart();    
      // 設置HTML內容    
      html.setContent(mailInfo.getContent(), "text/html; charset=utf-8");    
      mainPart.addBodyPart(html);    
      // 將MiniMultipart對象設置爲郵件內容    
      mailMessage.setContent(mainPart);    
      // 發送郵件    
      Transport.send(mailMessage);    
      return true;    
      } catch (MessagingException ex) {    
          ex.printStackTrace();    
      }    
      return false;    
    }    
code

 

5,在類中,實現發送郵件,建議另起線程發送郵件xml

 

/**
  * 發送郵件內部類
  *
  */
 class SendEmailThread implements Runnable {
  private MailSenderInfo mailInfo;

 

  public SendEmailThread(MailSenderInfo mailInfo) {
   this.mailInfo = mailInfo;
  }

 

  @Override
  public void run() {
   try {
    if (this.mailInfo != null) {
     SimpleMailSender.sendHtmlMail(mailInfo);
    }
   } catch (Exception e) {
    e.printStackTrace();
   }
  }
 }

 

 /**
  * 發送郵件方法
  * 
  * @param account   * @param code   */  public void sendEmail(String account, String code) {   WebApplicationContext ac = ContextLoader.getCurrentWebApplicationContext();   // 獲取當前服務IP   MailSenderInfo mailInfo = (MailSenderInfo) ac.getBean("mailInfo");   mailInfo.setValidate(Boolean.TRUE);   mailInfo.setToAddress(account);   mailInfo.setSubject("驗證碼郵件");   mailInfo.setContent(     "<p>您好!</p><p>感謝您註冊成爲xxxxxx用戶!</p><p>您的驗證碼是:" + code + "。祝您使用愉快!</p><p>點擊xxxxxxxxx瞭解更多產品。</p>xxxxxxxx</p>");   SendEmailThread d = new CloudResourceImpl().new SendEmailThread(mailInfo);   Thread t = new Thread(d);   t.start();  }
