Apache Commons Email 简单使用
2014-03-31 14:31

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:
[java]
view plaincopyprint?
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("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:
[java]
view plaincopyprint?
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("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:
[java]
view plaincopyprint?
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("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:
[java]
view plaincopyprint?
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("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:
[java]
view plaincopyprint?
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。
