通过JAVA发送邮件--mail.jar

通过JAVA发送email. 需要下载mail.jar. 第4个java代码的些设置根据实际情况设置。

本例是针对goole邮件服务：google mail: smtp.gmail.com 465 需要启用ssl。其他的可以网上参考。

1. MailSenderInfo

import java.util.Properties;

public class MailSenderInfo {
  private String mailServerHost;
  private String mailServerPort = "25";
   private String fromAddress;
   private String toAddress;
  private String userName;
  private String password;
  private boolean validate = false;
  private String subject;
  private String content;
  private String[] attachFileNames;
  private boolean ssl;
  final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";

  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");
   if(ssl) p.put("mail.smtp.socketFactory.class", SSL_FACTORY);
   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 boolean isSsl() {
   return ssl;
  }

  public void setSsl(boolean ssl) {
   this.ssl = ssl;
  }
}

2. MyAuthenticator

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

public class MyAuthenticator extends Authenticator {
String userName = null;
String password = null;

public MyAuthenticator() {

}

public MyAuthenticator(String username, String password) {
  this.userName = username;
  this.password = password;
}
protected PasswordAuthentication getPasswordAuthentication() {
  return new PasswordAuthentication(userName, password);
}
}
