专门做了这个例子;而java的这个例子好像就是为了教学而写的,很多教学目的的例子是不考虑优化、性能的。
利用JavaMail发送邮件必要用到mail.jar和activtion.jar两个包。
该类完成了较完全的邮件发送功效,包含以HTML格局发送,增加附件和抄送人。上面是详细的代码:
Mail.java:- packagecn.cgw.util.mail;
- importjava.util.Properties;

- importjavax.activation.FileDataSource;

- privateSessionsession;//邮件会话对象
- privatePropertiesprops;//体系属性
- privatebooleanneedAuth=false;//smtp是不是必要认证
- //smtp认证用户名和暗码
- privateStringusername;
- privateStringpassword;
- privateMultipartmp;//Multipart对象,邮件内容,题目,附件等外容均增加到个中后再天生MimeMessage对象

复制代码 测试代码:- publicstaticvoidmain(String[]args){
- Stringsmtp="SMTP服务器";
- Stringfrom="发信人";
- Stringto="收信人";
- Stringcopyto="抄送人";
- Stringsubject="邮件主题";
- Stringcontent="邮件内容";
- Stringusername="用户名";
- Stringpassword="暗码";
- Stringfilename="附件路径,如:F:条记<a>struts2</a>与mvc.txt";
- Mail.sendAndCc(smtp,from,to,copyto,subject,content,username,password,filename);
- }
复制代码 其实你不用Struts,spring这些工具,直接用jsp,servlet能够很方便地写出来,而且,可以根据个人的水平、爱好,有很多方案。而struts,spring这些工具的出来。 |
