学步园

*第一步：工程中添加javamail需要的两个jar 

地址：可以再sun官方网上去下载。 

list：mail.jar、activation.jar

*第二步：写发邮件的属性文件，本人不喜欢硬编码的方式coding。

mail.properties文件如下：

mail.transport.protocol=smtp<br /> mail.host=smtp.gmail.com<br /> mail.smtp.auth=true<br /> mail.smtp.port=465<br /> mail.username=xxxx<br /> mail.password=xxx<br /> mail.from=xxx@gmail.com<br /> mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory<br /> mail.smtp.socketFactory.fallback=false<br /> mail.smtp.socketFactory.port=465 *第三步，写java类。

MailSender.java
