private String mailServerPort;
@Value("${userName}")
private String userName;
@Value("${password}")
private String password;

@Override
public void send(String title,String content) {
MailSenderInfo mailSenderInfo = new MailSenderInfo();
mailSenderInfo.setMailServerHost(mailServerHost);
mailSenderInfo.setMailServerPort(mailServerPort);
mailSenderInfo.setValidate(true);
mailSenderInfo.setUserName(userName);
mailSenderInfo.setPassword(password);//您的邮箱密码
mailSenderInfo.setFromAddress(userName);
String [] to = tos.split(",");
mailSenderInfo.setToAddress(to);
mailSenderInfo.setSubject(title);
mailSenderInfo.setContent(content);
//这个类主要来发送邮件
SimpleMailSender sms = new SimpleMailSender();

package cn.*.*.common.mail;

5.测试类
package cn.*.*.common.mail;
public class SendMail {
public static void main(String[] args){
//这个类主要是设置邮件
MailSenderInfo mailInfo = new MailSenderInfo();
mailInfo.setMailServerHost("smtp.qq.com");
mailInfo.setMailServerPort("25");
mailInfo.setValidate(true);
mailInfo.setUserName("3056576606@qq.com");
mailInfo.setPassword("Js2015UHB!Q");//您的邮箱密码
mailInfo.setFromAddress("3056576606@qq.com");
String [] tos = new String[]{"3056576606@qq.com","14472656@qq.com"};
mailInfo.setToAddress(tos);
mailInfo.setSubject("test jsj send mail11");
mailInfo.setContent("设置邮箱内容 如http://www.guihua.org 中国桂花网 是中国最大桂花网站==");
//这个类主要来发送邮件
SimpleMailSender sms = new SimpleMailSender();
sms.sendTextMail(mailInfo);//发送文体格式
// sms.sendHtmlMail(mailInfo);//发送html格式
}
}
