JavaMail

登录到：http://java.sun.com/products/javamail/downloads/index.html站点下载JavaMail的版本目前最新的是JavaMail 1.4.4

下载后解压使用其中的mail.jar包，该文件是JavaMail的全功能JAR包。

JavaMail还依赖于另外一个组件：JAF(JavaBeans Activation franmework) 还需要下载该包http://java.sun.com/products/jaf/downlowads/index.html，下载后使用Activation.jar包。该文件就是JAF组件的二进制包，将该包JAR添加到项目的类加载路径即可。

JavaMail的常用API

(1)javax.mail.Session

Session类代表JavaMail的一次邮件会话：

=》Session.getDefaultInstance(Properties props)

=》Session.getDefaultInstance(Properties props,Authenticator a)

(2)java.mail.Transport  使用Transoprt完成邮件的发送

Transport.send(MimeMessage msg)

Transport有一个直接子类：com.sun.mail.smtp.SMTPTransport,实现了Transport这个抽象类

（3）javax.mail.Store

该类是实现邮件协读/写/监视/查找等操作

Store store = session.getStore(java.lang.String protocol);

store.connect(popserver,username,passwrod);

(4)javax.mail.Folder

Folder用于分级组织邮件，代表邮件系统的一个文件夹

Folder fo = store.getFolder("INBOX");

fo.open(Folder.READ_ONLY);

（5）Java.mail.MimeMessage

该对象是实际电子邮件对象

该类的含有一下属性：

protected byte[] content:该邮件内容的字节数组

protected InternetHeaders header:返回保存该E-mail文件头的对象

方法：

void addFrom(Address[] addresses):为该E-mail设置发件人地址

void addHeader(String name,String value):在E-mail 的文件头内容上增加value;

void addRecipients(Message.RecipientType type Address[] address);指定类型的收件地址

Address[]  getFrom();返回发件人地址列表

void setContent(Multipart mp)：为该E-mail设置内容

（6）javax.mail.Address

该对象用于确定发件人和收件人的地址，和message一样

(7)javax.mail.Multipart

是用于保存电子邮件内容的容器，它定义了增加和删除/获得电子邮件的方法。

(8)javax.mail.BodyPart

该类表示邮件内容的一个部分。它是一个抽象类，通常使用其子类：javax.mail.Internet.MimeBodyPart.

（9）javax.activation.DataHandler

该类允许邮件信息包含非文本的BodyPart对象。

（10）java.activation.FileDataSource

该类代表本地文件和服务器可以直接访问的资源。

（11）

该类代表一个远程资源。其他类似与FileDataSource。但实际上不如FileDataSource的常用
