本文介绍了如何在SpringBoot项目中使用JavaMailSenderImpl发送邮件，包括添加依赖、配置properties文件、创建MailConfig和MailUtil类，以及解决可能出现的AuthenticationFailedException问题。特别指出，若使用QQ邮箱，需更改服务地址并开启SMTP服务。

一、首先在pom中添加依赖

<dependency>
            <groupId>javax.mail</groupId>
            <artifactId>javax.mail-api</artifactId>
            <version>1.5.6</version>
        </dependency>
        <dependency>
            <groupId>com.sun.mail</groupId>
            <artifactId>javax.mail</artifactId>
            <version>1.5.6</version>
        </dependency>

二、在resources目录下创建mail.properties文件添加配置

#服务器 （若想使用QQ邮箱，请参考第六步）
mailHost=smtp.163.com
#端口号 
mailPort=25
#邮箱账号(改成自己的,此为发送邮件方的账号，注意得是163账号)
mailUsername=XXXX@163.com
#邮箱密码(改成自己的)
mailPassword=XXXX
#时间延迟
mailTimeout=25000

三、创建一个MailConfig类来配置基本信息

package com.lw.study.mail;

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

/**
 * @author: 
 * @Date: 10:30 2018/8/29
 */
public class MailConfig {
    public static final String PROPERTIES_DEFAULT = "mail.properties";
    public static String host;
    public static Integer port;
    public static String userName;
    public static String passWord;
    public static String emailForm;
    public static String timeout;
    public static String personal;
    public static Properties properties;

    static {
        init();
    }

    private static void init(){
        properties = new Properties();
        try {
            //获取配置文件内容
            InputStream inputStream = MailConfig.class.getClassLoader().getResourceAsStream(PROPERTIES_DEFAULT);
            properties.load(inputStream);
            inputStream.close();
            //给属性赋值
            host = properties.getProperty("mailHost");
            port = Integer.parseInt(properties.getProperty("mailPort"));
            userName = properties.getProperty("mailUsername");
            passWord = properties.getProperty("mailPassword");
            emailForm = properties.getProperty("mailUsername");
            timeout = properties.getProperty("mailTimeout");
            //发送人
            personal = "汤姆猫";
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

四、创建一个MailUtil类写发送邮件的方法

package com.lw.study.mail;


import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.UnsupportedEncodingException;
import java.util.Properties;

/**
 * @author: 
 * @Date: 10:42 2018/8/29
 */
public class MailUtil {
    private static final String HOST = MailConfig.host;
    private static final Integer PORT = MailConfig.port;
    private static final String USERNAME = MailConfig.userName;
    private static final String PASSWORD = MailConfig.passWord;
    private static final String EMAILFROM = MailConfig.emailForm;
    private static final String TIMEOUT = MailConfig.timeout;
    private static final String PERSONAL = MailConfig.personal;
    private static JavaMailSenderImpl mailSender = createMailsender();

    /**
     * 配置好的工具
     * @return
     */
    private static JavaMailSenderImpl createMailsender(){
        JavaMailSenderImpl sender = new JavaMailSenderImpl();
        sender.setHost(HOST);
        sender.setPort(PORT);
        sender.setUsername(USERNAME);
        sender.setPassword(PASSWORD);
        sender.setDefaultEncoding("UTF-8");
        Properties p = new Properties();
        p.setProperty("mail.smtp.timeout", TIMEOUT);
        p.setProperty("mail.smtp.auth", "false");
        sender.setJavaMailProperties(p);
        return sender;
    }

    /**
     * 发送邮件
     * @param to 接收人
     * @param subject 主题
     * @param html 发送内容
     * @throws MessagingException
     * @throws UnsupportedEncodingException
     */
    public static void sendMail(String to, String subject, String html)
            throws MessagingException,UnsupportedEncodingException {

        MimeMessage mimeMessage = mailSender.createMimeMessage();
        //设置编码
        MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true, "UTF-8");
        mimeMessageHelper.setFrom(EMAILFROM,PERSONAL);
        mimeMessageHelper.setTo(to);
        mimeMessageHelper.setSubject(subject);
        mimeMessageHelper.setText(html,true);
        mailSender.send(mimeMessage);

    }


}

五、来试一下发送邮件

package com.lw.study.mail;

import javax.mail.MessagingException;
import java.io.UnsupportedEncodingException;

/**
 * @author: 
 * @Date: 10:58 2018/8/29
 */
public class Client {
    public static void main(String[] args) {
        try {
            //这里的邮箱是接受者的邮箱，和配置的邮箱不一样
            MailUtil.sendMail("XXXXX@163.com","我来发个邮件玩玩","come on");
        } catch (MessagingException e) {
            e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
    }
}

六、注意

如果运行出错：Exception in thread “main” javax.mail.AuthenticationFailedException: 535 Error: authentication failed
1.检查配置的用户名密码是否正确
2.如果在mail.properties文件中配置的服务为：smtp.163.com,那么你的邮箱必须是XXX@163.com的邮箱。
