本文实例为大家分享了Spring Boot利用Java Mail实现邮件发送的具体代码，供大家参考，具体内容如下

实现邮件发送的方法有很多，这里只是简单记录一个demo实现

1. 引入maven依赖

<!-- https://mvnrepository.com/artifact/org.springframework/spring-context-support -->
 <dependency>
 <groupId>org.springframework</groupId>
 <artifactId>spring-context-support</artifactId>
 <version>3.2.0.RELEASE</version>
 </dependency>
 <dependency>
 <groupId>javax.mail</groupId>
 <artifactId>mail</artifactId>
</dependency>

2. 配置邮箱bean信息

我的配置文件名称是application-bean.xml

我是用qq邮箱做的测试，这里需要注意的是password要配置成邮箱授权码，不是邮箱密码

简单说下邮箱授权码的获取方式：

登录网页版QQ邮箱 > 设置 > 账户，需要保证 SMTP 服务开启

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
 
 <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
 <property name="host" value="smtp.qq.com"/>
 <property name="port" value="465"/>
 <property name="defaultEncoding" value="utf-8"/>
 <property name="username" value="你的邮箱地址"/>
 <property name="password" value="你的邮箱授权码（不是邮箱密码）"/>
 <property name="javaMailProperties">
  <props>
  <prop key="mail.smtp.sendpartial">true</prop>
  <prop key="mail.smtp.auth">true</prop>
  <prop key="mail.smtp.socketFactory.port">465</prop>
  <prop key="mail.smtp.socketFactory.class">javax.net.ssl.SSLSocketFactory</prop>
  </props>
 </property>
 </bean>
 <bean class="com.amwalle.walle.util.Mail">
 <property name="mailSender" ref="mailSender"/>
 </bean>
</beans>

3. 加载bean配置信息

实现了一个BeanConfig类：

package com.amwalle.walle.bean;
 
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
 
@Configuration
@ImportResource(locations={"classpath:/application-bean.xml"})
public class BeanConfig {
}

4. 邮件发送类

简单实现了一个邮件发送的类，其中包含发送邮件方法 sendMail：

package com.amwalle.walle.util;
 
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;
 
import javax.mail.internet.MimeMessage;
 
public class Mail {
 private static final Logger logger = LoggerFactory.getLogger(Mail.class);
 
 private static JavaMailSenderImpl mailSender;
 
 public static void sendMail(String title, String html, String to) {
 try {
  MimeMessage msg = mailSender.createMimeMessage();
  MimeMessageHelper helper = new MimeMessageHelper(msg, true);
  helper.setFrom(mailSender.getUsername());
  helper.setTo(to);
  helper.setSubject(title);
  helper.setText(html, true);
  mailSender.send(msg);
 } catch (Exception e) {
  logger.error("sendMail error", e);
 }
 }
 
 public void setMailSender(JavaMailSenderImpl mailSender) {
 Mail.mailSender = mailSender;
 }
 
 public JavaMailSenderImpl getMailSender() {
 return mailSender;
 }
}

5. 测试邮件发送

调用邮件发送，检查是否发送成功：

package com.amwalle.walle.controller;
 
import com.amwalle.walle.util.Mail;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
 
@RestController
@EnableAutoConfiguration
public class HelloWorldController {
 private static final Logger logger = LoggerFactory.getLogger(HelloWorldController.class);
 
 @RequestMapping(value = "/walle", method = RequestMethod.GET)
 public String helloWorld() {
 logger.info("--------test-------");
 
 Mail.sendMail("test","test", "接收邮箱地址");
 
 return "hello world";
 }
}
