java发邮件

//import org.springframework.mail.SimpleMailMessage;//import org.springframework.mail.javamail.JavaMailSenderImpl;        JavaMailSenderImpl m = new JavaMailSenderImpl();        m.setHost("smtp.163.com");        m.setUsername("[e-mail]");        m.setPassword("xxx");        Properties ps = new Properties();        ps.put("mail.smtp.auth", "true");        ps.put("mail.smtp.timeout", "10000");        m.setJavaMailProperties(ps);                SimpleMailMessage mailMessage  =   new  SimpleMailMessage();        mailMessage.setTo("[e-mail]");        mailMessage.setFrom("[e-mail]");        mailMessage.setText("xxx");        mailMessage.setSubject("xxx");                m.send(mailMessage);

 

另外：
1、使用了spring包，不用spring也行但是写法麻烦，代码不好看

2、可以将JavaMailSenderImpl实例化交给spring
