Apache Commons Email 简单使用

 

注： 本文转载是http://blog.csdn.net/yuaoi/archive/2010/08/18/5818561.aspx 下，仅供自己学习参考。

Commons Email aims to provide a API for sending email. It is built on top of the Java Mail API, which it aims to simplify.

Some of the mail classes that are provided are as follows:

• SimpleEmail - This class is used to send basic text based emails.
• MultiPartEmail - This class is used to send multipart messages. This allows a text message with attachments either inline or attached.
• HtmlEmail - This class is used to send HTML formatted emails. It has all of the capabilities as MultiPartEmail allowing attachments to be easily added. It also supports embedded images.
• EmailAttachment - This is a simple container class to allow for easy handling of attachments. It is for use with instances of MultiPartEmail and HtmlEmail.

说明：这个是Apache的一个开源项目，是基于另一个开源项目Java Mail上而进行封装的，使用起来更加简单方便。官网：

首先下载jar包：commons-email-1.2.jar

http://repo1.maven.org/maven2/org/apache/commons/commons-email/1.2/commons-email-1.2.jar

1、先来一个简单文本邮件发送的例子：

 

package com.mail.test;  
import org.apache.commons.mail.DefaultAuthenticator;  
import org.apache.commons.mail.EmailException;       
import org.apache.commons.mail.SimpleEmail;        
   
public class BaseEmailSend     
{    
    public BaseEmailSend()    
    {    
            
    }    
        
        
    public static void send()    
    {    
        SimpleEmail email = new SimpleEmail();       
        //email.setTLS(true); //是否TLS校验，，某些邮箱需要TLS安全校验，同理有SSL校验  
        email.setDebug(true);  
        //email.setSSL(true);          
        email.setHostName("smtp.163.com");   
        email.setAuthenticator(new DefaultAuthenticator("[e-mail]", "yuaio"));  
        try     
        {    
         email.setFrom("[e-mail]"); //发送方,这里可以写多个  
         email.addTo([e-mail]); // 接收方  
         email.addCc("402******@qq.com"); // 抄送方  
         email.addBcc("[e-mail]"); // 秘密抄送方  
         email.setCharset("GB2312");  
         email.setSubject("标题哦"); // 标题  
         email.setMsg("测试测试内容，请查阅！！！);// 内容  
         email.send();  
         System.out.println("发送成功");  
        } catch (EmailException e) {    
            e.printStackTrace();    
        }     
    }    
      
    public static void main(String[] args)    
    {    
        send();    
    }    
}  

 注意：email.setHostName("smtp.163.com"); 

 

         email.setAuthenticator(new DefaultAuthenticator("[e-mail]", "yuaio"));

还有email.setTLS(true); email.setSSL(false); 这些都应该是对应的，使用不同的服务商邮箱，这里的HostName需要改一下，同时安全校验也是不同的，据我测试：只有google gmail邮箱这两个校验都需要（google邮箱是我的最爱，好用，快速，最最重要的是安全，给你足够的隐私权。）设email.setTLS(true); email.setSSL(true);

163：两个都不需要校验就能通过；

sina：两个都不需要校验就能通过；

qq邮箱：需要需要校验tls；

email.setDebug(true); 开启debug模式，可以打印一些信息。

2、带附件的邮箱发送：

package com.mail.test;
import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.EmailAttachment;
import org.apache.commons.mail.EmailException;     
import org.apache.commons.mail.MultiPartEmail;
 
public class EmailWithAffixSend   
{ 
    public EmailWithAffixSend()  
    {  
          
    }  
      
      
    public static void send()  
    {  
     MultiPartEmail  email = new MultiPartEmail();     
        //email.setTLS(true); //是否TLS校验，，某些邮箱需要TLS安全校验，同理有SSL校验
        email.setDebug(true);
        //email.setSSL(true);        
        email.setHostName("smtp.sina.com"); 
        email.setAuthenticator(new DefaultAuthenticator("[e-mail]", "******"));
        try   
        {  
   // Create the attachment
   EmailAttachment attachment = new EmailAttachment();
   //绝对路径
   attachment.setPath("F:\\dgjl.jpg");
   attachment.setDisposition(EmailAttachment.ATTACHMENT);
   attachment.setDescription("Picture of John");
   attachment.setName("John");
   email.setFrom("[e-mail]"); //发送方
   email.addTo("[e-mail]"); // 接收方
   //email.addCc("[e-mail]"); // 抄送方
   //email.addBcc("[e-mail]"); // 秘密抄送方
   email.setCharset("GB2312");//编码
   email.setSubject("有附件!!!"); // 标题
   email.setMsg("邮件发送测试"); // 内容
   email.attach(attachment);
   email.send();
   System.out.println("发送成功");
        } catch (EmailException e) {  
            e.printStackTrace();  
        }   
    }  
    
    public static void main(String[] args)  
    {  
        send();  
    }  
}

 3、附件图片是url链接的：

package com.mail.test;
import java.net.MalformedURLException;
import java.net.URL;
import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.EmailAttachment;
import org.apache.commons.mail.EmailException;     
import org.apache.commons.mail.MultiPartEmail;
import org.apache.commons.mail.SimpleEmail;      
 
public class EmailWithUrlAffixSend   
{  
    public EmailWithUrlAffixSend()  
    {  
          
    }  
      
      
    public static void send()  
    {  
     MultiPartEmail  email = new MultiPartEmail();     
        email.setTLS(true); //是否TLS校验，，某些邮箱需要TLS安全校验，同理有SSL校验
        email.setDebug(false);
        //email.setSSL(true);        
        email.setHostName("smtp.sina.com"); 
        email.setAuthenticator(new DefaultAuthenticator("[e-mail]", "******"));
        try   
        {  
   // Create the attachment
   EmailAttachment attachment = new EmailAttachment();
   attachment.setURL(new URL("http://www.apache.org/images/asf_logo_wide.gif"));
   attachment.setDisposition(EmailAttachment.ATTACHMENT);
   attachment.setDescription("Apache logo");
   attachment.setName("我的份");

   email.setFrom("[e-mail]"); //发送方
   email.addTo("[e-mail]"); // 接收方
   //email.addCc("[e-mail]"); // 抄送方
   //email.addBcc("[e-mail]"); // 秘密抄送方
   email.setCharset("GB2312");
   email.setSubject("有附件!!!"); // 标题
   email.setMsg("邮件发送测试。"); // 内容
   email.attach(attachment);
   email.send();
   System.out.println("发送成功");
        } catch (EmailException e) {  
            e.printStackTrace();  
        }catch (MalformedURLException e) {
   e.printStackTrace();
  }   
    }  
    
    public static void main(String[] args)  
    {  
        send();  
    }  
}

 4、html格式邮件发送：

package com.mail.test;
import java.net.MalformedURLException;
import java.net.URL;
import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.EmailAttachment;
import org.apache.commons.mail.EmailException;     
import org.apache.commons.mail.HtmlEmail;
import org.apache.commons.mail.MultiPartEmail;
import org.apache.commons.mail.SimpleEmail;      
 
public class HtmlEmailSend   
{  
    public HtmlEmailSend()  
    {  
          
    }  
      
    public static void send()  
    {  
  // Create the email message
  HtmlEmail email = new HtmlEmail();
  email.setHostName("smtp.163.com");
  email.setTLS(true); //是否TLS校验，，某些邮箱需要TLS安全校验，同理有SSL校验
  email.setAuthenticator(new DefaultAuthenticator("[e-mail]", "******"));
  try {
   email.setCharset("GB2312");
   email.addTo("[e-mail]", "java");
   email.setFrom("[e-mail]", "java");
   email.setSubject("内嵌图片背景测试");
   // embed the image and get the content id
   URL url = new URL("http://www.jianlimuban.com/resume/images/20081112155017201.jpg");
   String cid = email.embed(url, "Apache logo");
   // set the html message
   email.setHtmlMsg("<html>The apache logo - <img src="\" mce_src="\""cid:" + cid + "\"></html>");
   // 假如图片失效时显示的文字
   email.setTextMsg("Your email client does not support HTML messages");
   // send the email
   email.send();
   System.out.println("发送成功");
        } catch (EmailException e) {  
            e.printStackTrace();  
        }catch (MalformedURLException e) {
   e.printStackTrace();
  }   
    }  
    
    public static void main(String[] args)  
    {  
        send();  
    }  
}

 异常：开始放在测试项目中还是发送成功的，但是移到另一个项目中，抛异常了：Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream  

查找资料有朋友也遇到过，是因为MyEclipse中系统自带的email.jar与导入的mail.jar包冲突不一致引起的，删除系统中的jar包即可：

这里引用这位朋友的方法吧：

用rar打开X:/Program Files/MyEclipse 6.0/myeclipse/eclipse/plugins/com.genuitec.eclipse.j2eedt.core_6.0.1.zmyeclipse601200710/data/libraryset/EE_5/javaee.jar
,然后删除mail,一切就OK了。
