准备工作
修改 163 邮箱的 POP3 配置，备份授权码。详情请参考：传送门
添加依赖
在 pom.xml 文件中加入下面依赖（如果有就不用加了）
xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>配置授权码
在 application.properties 文件中配置授权码
properties
spring.mail.host=smtp.163.com
spring.mail.username=邮箱
spring.mail.password=授权码
spring.mail.port=25
spring.mail.protocol=smtp
spring.mail.default-encoding=UTF-8封装工具类 Mail.java
java
package com.api.utils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
@Service
public class Mail {
@Value("${spring.mail.username}")
private String from;
@Autowired
private JavaMailSender mailSender;
/**
* 简单文本邮件
* @param to 接收者邮件
* @param subject 邮件主题
* @param content 邮件内容
*/
public void sendSimpleMail(String to, String subject, String content){
SimpleMailMessage message = new SimpleMailMessage();
message.setTo(to);
message.setSubject(subject);
message.setText(content);
message.setFrom(from);
mailSender.send(message);
}
/**
* HTML 文本邮件
* @param to 接收者邮件
* @param subject 邮件主题
* @param content HTML内容
* @throws MessagingException
*/
public void sendHtmlMail(String to, String subject, String content) throws MessagingException {
MimeMessage message = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);
helper.setFrom(from);
mailSender.send(message);
}
}在 Controller 中使用工具类
