小编给大家分享一下如何使用velocity实现自定义模板发送邮件，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
邮件发送，可以自定义模板，使用velocity或者thymeleaf均可。
本文以velocity为例：
计算
安全
数据库
网络和加速
企业服务
package cn.xing.util;
import org.apache.velocity.app.VelocityEngine;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;
import javax.mail.internet.MimeUtility;
import org.springframework.ui.velocity.VelocityEngineUtils;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Map;
import java.util.Properties;
@Service
public class MailSender implements InitializingBean {
private static final Logger logger = LoggerFactory.getLogger(MailSender.class);
private JavaMailSenderImpl mailSender;
@Autowired
private VelocityEngine velocityEngine;
public boolean sendWithHTMLTemplate(String to, String subject, String template, Map<String, Object> model) {
try {
String nick = MimeUtility.encodeText("牛客中级课");
InternetAddress from = new InternetAddress(nick + "<course@nowcoder.com>");
MimeMessage mimeMessage = mailSender.createMimeMessage();
MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage);
//设置邮件模板
String result = VelocityEngineUtils.mergeTemplateIntoString(velocityEngine, template, "UTF-8", model);
mimeMessageHelper.setTo(to);
mimeMessageHelper.setFrom(from);
mimeMessageHelper.setSubject(subject);
mimeMessageHelper.setText(result, true);
mailSender.send(mimeMessage);
return true;
} catch (Exception e) {
logger.error("发送邮件失败" + e.getMessage());
return false;
}
}
@Override
public void afterPropertiesSet() throws Exception {
mailSender = new JavaMailSenderImpl();
mailSender.setUsername("course@nowcoder.com");
mailSender.setPassword("NKnk66");
mailSender.setHost("smtp.exmail.qq.com");
mailSender.setPort(465);
mailSender.setProtocol("smtps");
mailSender.setDefaultEncoding("utf8");
Properties javaMailProperties = new Properties();
javaMailProperties.put("mail.smtp.ssl.enable", true);
mailSender.setJavaMailProperties(javaMailProperties);
}
}使用：
@Autowired
MailSender mailSender;
public void testmail() {
Map<String, Object> map = new HashMap<String, Object>();
map.put("username","我是邮件内容呀");
//mails/welcome.html是templates里的html模板
mailSender.sendWithHTMLTemplate("123123@163.com", "登陆异常", "mails/welcome.html",
map);
}Thymeleaf用法类似。
