       JavaMail下載好后，我們來看一下其主要內(nèi)容：

javax.mail.session：上下文環(huán)境信息，如服務(wù)器的主機(jī)名、端口號(hào)、協(xié)議名稱等  javax.mail.Message：郵件模型，發(fā)送郵件和接收郵件的媒介，封裝了郵件的信息，如發(fā)件人、收件人、郵件標(biāo)題、郵件內(nèi)容等  javax.mail.Transport：連接郵件SMTP服務(wù)器，發(fā)送郵件  javax.mail.Store：連接郵件POP3、IMAP服務(wù)器，收取郵件   %20 %20 %20 通過這些類，最終就可以實(shí)現(xiàn)收發(fā)郵件，一個(gè)發(fā)送郵件的簡單示例：[java] view%20plain copy print?public class JavaMailTest1 {      public static void main(String[] args) throws MessagingException {          Properties props = new Properties();          // 開啟debug調(diào)試          props.setProperty("mail.debug", "true");          // 發(fā)送服務(wù)器需要身份驗(yàn)證          props.setProperty("mail.smtp.auth", "true");          // 設(shè)置郵件服務(wù)器主機(jī)名          props.setProperty("mail.host", "smtp.163.com");          // 發(fā)送郵件協(xié)議名稱          props.setProperty("mail.transport.protocol", "smtp");                    // 設(shè)置環(huán)境信息          Session session = Session.getInstance(props);                    // 創(chuàng)建郵件對(duì)象          Message msg = new MimeMessage(session);          msg.setSubject("JavaMail測(cè)試");          // 設(shè)置郵件內(nèi)容          msg.setText("這是一封由JavaMail發(fā)送的郵件！");          // 設(shè)置發(fā)件人          msg.setFrom(new InternetAddress("java_mail_001@163.com"));                    Transport transport = session.getTransport();          // 連接郵件服務(wù)器          transport.connect("java_mail_001", "javamail");          // 發(fā)送郵件          transport.sendMessage(msg, new Address[] {new InternetAddress("java_mail_002@163.com")});          // 關(guān)閉連接          transport.close();      }  }         最終運(yùn)行后，郵件發(fā)送成功。由于我們開啟了debug調(diào)試，在控制臺(tái)可以看到JavaMail和服務(wù)器之間的交互信息記錄，可以發(fā)現(xiàn)，和Java Mail(一)：telnet實(shí)現(xiàn)發(fā)送收取郵件中telnet下的命令及服務(wù)器反饋信息基本一致。       創(chuàng)建Session對(duì)象時(shí)可能需要的屬性詳細(xì)信息如下：

Name	Type	Description
mail.debug	boolean	The initial debug mode. Default is false.
mail.from	String	The return email address of the current user, used by the InternetAddressmethodgetLocalAddress.
mail.mime.address.strict	boolean	The MimeMessage class uses the InternetAddress method parseHeader to parse headers in messages. This property controls the strict flag passed to theparseHeader method. The default is true.
mail.host	String	The default host name of the mail server for both Stores and Transports. Used if themail.protocol.host property isn't set.
mail.store.protocol	String	Specifies the default message access protocol. The SessionmethodgetStore() returns a Store object that implements this protocol. By default the first Store provider in the configuration files is returned.
mail.transport.protocol	String	Specifies the default message transport protocol. The SessionmethodgetTransport() returns a Transport object that implements this protocol. By default the first Transport provider in the configuration files is returned.
mail.user	String	The default user name to use when connecting to the mail server. Used if the mail.protocol.user property isn't set.
mail.protocol.class	String	Specifies the fully qualified class name of the provider for the specified protocol. Used in cases where more than one provider for a given protocol exists; this property can be used to specify which provider to use by default. The provider must still be listed in a configuration file.
mail.protocol.host	String	The host name of the mail server for the specified protocol. Overrides the mail.host property.
mail.protocol.port	int	The port number of the mail server for the specified protocol. If not specified the protocol's default port number is used.
mail.protocol.user	String	The user name to use when connecting to mail servers using the specified protocol. Overrides themail.user property.
