配置式的javamail

共有5个类  一个测试类  1个配置文件

Class  Au

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

public  class Au extends Authenticator{
 JavaMailConfig jmd=null;
 
 
 
 public Au(JavaMailConfig jmd) {
  super();
  this.jmd = jmd;
 }

 @Override
 protected  PasswordAuthentication getPasswordAuthentication(){
    return new PasswordAuthentication(jmd.getUsername(), jmd.getPassword());
   }

}

class JavaMailConfig

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

public  class JavaMailConfig {
 static InputStream is=JavaMailConfig.class.getClassLoader().getResourceAsStream("javamail.properties");

 }

 public   Properties getProperties(){

Class javaMailVO

public class JavaMailVO {
 private String[] FCCRecipients;
 private String[] BCCRecipients;
 private String subject;
 public String getSubject() {
  return subject;
 }
 public void setSubject(String subject) {
  this.subject = subject;
 }
 private String content;

  return FCCRecipients;
 }

 }

}

Class javaMailUtil

import java.util.Properties;

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 JavaMailUtil {
 static JavaMailConfig jmd=new JavaMailConfig();
 public static void sendJavaMail(JavaMailVO jmvo) {

  Properties prop = jmd.getProperties();
  Au auth = new Au(jmd);
  Session session = Session.getInstance(prop, auth);
  MimeMessage msg = new MimeMessage(session);
  try {
   msg.setFrom(new InternetAddress(jmd.getMaifrom()));
   StringBuffer sb=new StringBuffer();
   
   int i=0;
   for (String bcc:jmvo.getBCCRecipients()) {
     sb.append(bcc);
     i++;
     if(i<jmvo.getBCCRecipients().length){
      sb.append(",");
     }
   }
   
   msg.setFrom(new InternetAddress(prop.getProperty("maifrom")));
   msg.addRecipients(RecipientType.TO,sb.toString());
   msg.setSubject(jmvo.getSubject());
   msg.setContent(jmvo.getContent(), "text/html;charset=utf-8");
   Transport.send(msg);
   
   
  } catch (AddressException e) {
   e.printStackTrace();
  } catch (MessagingException e) {
   e.printStackTrace();
  }

 }

 public void sendJavaMail(String[] FCCRecipients, String BCCRecipients, String content) {

 }

}

可参考测试类编辑配置文件后直接使用

package mail;

import javax.mail.MessagingException;

import org.junit.Test;

public class TestJavaMail {
 @Test
 public void fun() throws MessagingException{
  JavaMailVO jmvo=new JavaMailVO();
  String[] bCCRecipients={"625959671@qq.com","631699895@qq.com"};
  jmvo.setBCCRecipients(bCCRecipients);
  String[] fCCRecipients={"625959671@qq.com","631699895@qq.com"};
  jmvo.setFCCRecipients(fCCRecipients);
  
  String subject="你好测试邮件";
  String content="内容：你好测试邮件sss";
  jmvo.setSubject(subject);
  jmvo.setContent(content);
  JavaMailUtil.sendJavaMail(jmvo);
 }

}
