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:
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:
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("[email protected]", "yuaio")); try { email.setFrom("[email protected]"); //发送方,这里可以写多个 email.addTo([email protected]); // 接收方 email.addCc("402******@qq.com"); // 抄送方 email.addBcc("[email protected]"); // 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("[email protected]", "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("[email protected]", "******")); 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("[email protected]"); //发送方 email.addTo("[email protected]"); // 接收方 //email.addCc("[email protected]"); // 抄送方 //email.addBcc("[email protected]"); // 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("[email protected]", "******")); 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("[email protected]"); //发送方 email.addTo("[email protected]"); // 接收方 //email.addCc("[email protected]"); // 抄送方 //email.addBcc("[email protected]"); // 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("[email protected]", "******")); try { email.setCharset("GB2312"); email.addTo("[email protected]", "java"); email.setFrom("[email protected]", "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("The apache logo - "); // 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。
