Apache Commons Email 简单运用

    博客分类:

阅读更多

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:

http://commons.apache.org/email/index.html

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:

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("yuaio@163.com", "yuaio"));   
        try      
        {     
         email.setFrom("yuaio@163.com"); //发送方,这里可以写多个   
         email.addTo("www@gmail.com"); // 接收方   
         email.addCc("402******@qq.com"); // 抄送方   
         email.addBcc("yuaio@163.com"); // 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("yuaio@163.com", "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:

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("java@sina.com", "******"));   
        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("java@sina.com"); //发送方   
   email.addTo("java@gmail.com"); // 接收方   
   //email.addCc("java@qq.com"); // 抄送方   
   //email.addBcc("java@163.com"); // 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:

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("java@sina.com", "******"));   
        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("java@sina.com"); //发送方   
   email.addTo("java@gmail.com"); // 接收方   
   //email.addCc("1234567@qq.com"); // 抄送方   
   //email.addBcc("java@163.com"); // 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:

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("java@163.com", "******"));   
  try {   
   email.setCharset("GB2312");   
   email.addTo("java@gmail.com", "java");   
   email.setFrom("java@163.com", "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。
