The debugging output will be written 23 ?* to System.out. 24 ?* ?25 ?* Sometimes you want to experiment with various security setting or features of 26 ?* commons-email.

This class works just like SimpleEmail except that it adds several 71 ?????* overloaded attach() methods to add attachments to the email. You can add 72 ?????* an unlimited number of attachments either inline or attached. The 73 ?????* attachments will be MIME encoded. 74 ?????* ?75 ?????* The simplest way to add the attachments is by using the EmailAttachment 76 ?????* class to reference your attachments. 77 ?????* ?78 ?????* In the following example, we will create an attachment for a picture. We 79 ?????* will then attach the picture to the email and send it. 80 ?????* ?81 ?????* </pre> 82 ?????* ?83 ?????* @describe 发送包含附件的邮件（附件为本地资源） 84 ?????* @throws EmailException 85 ?????*/ 86 ????public static void sendEmailsWithAttachments() throws EmailException { 87 ????????// Create the attachment 88 ????????EmailAttachment attachment = new EmailAttachment(); 89 ????????attachment.setPath("mypictures/john.jpg"); 90 ????????attachment.setDisposition(EmailAttachment.ATTACHMENT); 91 ????????attachment.setDescription("Picture of John"); 92 ????????attachment.setName("John"); 93 ?94 ????????// Create the email message 95 ????????MultiPartEmail email = new MultiPartEmail(); 96 ????????email.setHostName("mail.myserver.com"); 97 ????????email.addTo("jdoe@somewhere.org", "John Doe"); 98 ????????email.setFrom("me@apache.org", "Me"); 99 ????????email.setSubject("The picture");100 ????????email.setMsg("Here is the picture you wanted");101 102 ????????// add the attachment103 ????????email.attach(attachment);104 105 ????????// send the email106 ????????email.send();107 ????}108 109 ????/**110 ?????* <pre>111 ?????* 112 ?????* You can also use EmailAttachment to reference any valid URL for files113 ?????* that you do not have locally.

This class works exactly like the MultiPartEmail class with153 ?????* additional methods to set the html content, alternative text content if154 ?????* the recipient does not support HTML email, and add inline images.155 ?????* 156 ?????* In this example, we will send an email message with formatted HTML157 ?????* content with an inline image.158 ?????* 159 ?????* First, notice that the call to embed() returns a String. This String is a160 ?????* randomly generated identifier that must be used to reference the image in161 ?????* the image tag.162 ?????* 163 ?????* Next, there was no call to setMsg() in this example. The method is still164 ?????* available in HtmlEmail but it should not be used if you will be using165 ?????* inline images.
