Java implementation Send mail can be multiple attachments inline picture-commons-email use

Objective

Java implementation of the E-mail function, in fact, Sun in the Java EE Development package provides us with the relevant tools, using Mail.jar and Activation.jar can achieve this function, n years ago, including my first internship when the project was also implemented with sun provided package, to achieve a more cumbersome trouble, today we use Apache Toolkit Commons-email package to send with mail and embedded image function, it is the former made the next seal It is easier and easier to use, so we use Commons-email to send mail, we must also introduce Mail.jar, Activation.jar2 a dependency package, myeclipse is self-contained, so if you do not know Commons-email.jar also need to rely on this 2 package, once the project into other development environment, there may be classnotfund exception, do not know you may still be depressed , here to provide you with this three jar package for free: Java Mail function jar package free download, good nonsense, not to say, directly into the code, the code I commented very detailed, do not make redundant explanations, we see it.

Description

because of the time tight, has been busy project closed development, so first directly posted implementation code and test code, temporarily do not make layout and the various functions of the code description and attention, but the code comments are very detailed, we will understand, and so there will be time for the post to do further repair color and typesetting, The description of the code to the aspects of everyone better understanding and grasp, if there are any questions or suggestions, welcome message!
