如何用Java Mail在Spring Boot中高效实现邮件发送功能？

本文共计1002个文字，预计阅读时间需要5分钟。

本文以Spring Boot为例，分享了使用Java Mail实现邮件发送的简单示例代码，供大家参考。具体内容如下：

实现邮件发送的方法有很多，这里仅简单记录一个demo实现：

1. 引入maven依赖

xml org.springframework.boot spring-boot-starter-mail

2. 配置邮件发送

java@Configurationpublic class MailConfig { @Value(${spring.mail.host}) private String mailHost;

@Value(${spring.mail.username}) private String mailUsername;

@Value(${spring.mail.password}) private String mailPassword;

@Bean public JavaMailSender javaMailSender() { JavaMailSenderImpl mailSender=new JavaMailSenderImpl(); mailSender.setHost(mailHost); mailSender.setUsername(mailUsername); mailSender.setPassword(mailPassword); return mailSender; }}

3. 发送邮件

java@Servicepublic class MailService { @Autowired private JavaMailSender javaMailSender;

public void sendEmail(String to, String subject, String text) { SimpleMailMessage message=new SimpleMailMessage(); message.setTo(to); message.setSubject(subject); message.setText(text); javaMailSender.send(message); }}

以上代码展示了如何使用Spring Boot和Java Mail发送邮件。在实际项目中，可以根据需要修改配置和发送内容。

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

<!-- 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="www.springframework.org/schema/beans" xmlns:xsi="www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="www.springframework.org/schema/beans 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"; } }

附我的工程目录，需要修改的就是圈出来的这几个：
