之前曾经做过几个邮件发送类，有兴趣可以查阅前面的帖子。
使用过程中，发现一些不便之处，并作出了改进，将改进后的版本发布如下：

扩展类之一，这个可以作为发送邮件及附件的例子：
public class TestMailSender extends BaseMailService{
public static void main(String[] args) throws Exception{
TestMailSender s=new TestMailSender();
s.setSmtpServer("D230016.cn.ufo.com");
s.setSmtpUsername("XXXX");
s.setSmtpPassword("XXX");
s.setFromMailAddress("[email protected]");
s.setToMailAddress("[email protected]");
s.setCcMailAddress("");
s.setBccMailAddress("");
String[] arr=new String[2];
arr[1]="c://2.xml";
arr[0]="c://1.xml";
s.sendMail("title","content",arr);
}
}
扩展类之二，这个可以作为只发送邮件的例子：
public class RttsMailSender extends BaseMailService{
public RttsMailSender(){
super();
this.setSmtpServer("D230016.UFO.com");
this.setSmtpUsername("1234");
this.setSmtpPassword("5678");
this.setFromMailAddress("[email protected]");
}
public static void main(String[] args) throws Exception{
RttsMailSender s=new RttsMailSender();
s.setToMailAddress("[email protected]");
s.sendMail("hello", "world");
}
}
