JavaMail發(fā)送郵件

1、使用JavaMail發(fā)送郵件需要用到mail.jar和activtion.jar兩個(gè)包。該類實(shí)現(xiàn)了較完整的郵件發(fā)送功能，包括以HTML格式發(fā)送，添加附件和抄送人。下面是具體的代碼：Mail.java：Java代碼1. packagecn.cgw.util.mail;2. 3. importjava.util.Properties;4. 5. importjavax.activation.DataHandler;6. importjavax.activation.FileDataSource;7. importjavax.mail.Address;8. importjavax.mail.Body
