Java中发送邮件的方法之一，需要用到spring框架集成的JavaMailSenderImpl、SimpleMailMessage两个实现类。
一，创建一个service，代码如下：
public interface MailService {
public Boolean sendTextMail(String subject,String text,String to);
public Boolean sendHtmlMail(String subject,String text,String to);
}
二，service实现类如下：
@Service
public class MailServiceImpl implements MailService{
@Autowired
private JavaMailSenderImpl mailSender;
@Autowired
private SimpleMailMessage mailMessage; @Override
public Boolean sendTextMail(String subject,String text,String to) { //发送文本邮件，纯文字。
try {
mailMessage.setSubject(subject);
mailMessage.setText(text);
mailMessage.setTo(to);
mailSender.send(mailMessage);
return true;
} catch (Exception e) {
e.printStackTrace();
}
return false;
}
@Override
public Boolean sendHtmlMail(File file, String subject, String text, String to) { //发送HTML邮件，包含格式、图片、附件等
try {
MimeMessage mimeMessage =mailSender.createMimeMessage();
MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage,true); String from = ApplicationUtils.getApplicationSettings().getProperty("mail.from","xx@sina.com"); //这里的发送者是从配置文件中读取的。
messageHelper.setFrom(from);
messageHelper.setSubject(subject);
messageHelper.setTo(to);
messageHelper.setText("<html><head></head><body>"+text+"</body></html>", true);
//发送图片
/* FileSystemResource image = new FileSystemResource(new File("C:\\text.png")); //添加图片
messageHelper.addInline("img", image);*/
messageHelper.addAttachment(file.getName(), file); //添加附件
mailSender.send(mimeMessage);
return true; } catch (MessagingException e) { e.printStackTrace();
} return false;
} }
