SpringBoot添加Email发送功能及常见异常详解

1、完整的邮件发送代码

1.1、依赖包

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-support</artifactId>

<version>2.0.8</version>

<exclusions>

<exclusion>

<groupId>javax.servlet</groupId>

<artifactId>servlet-api</artifactId>

</exclusion>

</exclusions>

</dependency>

<dependency>

<groupId>javax.mail</groupId>

<artifactId>mail</artifactId>

<version>1.4.7</version>

</dependency>

主要用到了两个jar包：mail-1.4.7.jar、spring-support-2.0.8.jar.

1.2、邮件发送类

package com.autonavi.utils;

import java.util.Properties;

import javax.mail.MessagingException;

import javax.mail.internet.MimeMessage;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.mail.javamail.JavaMailSenderImpl;

import org.springframework.mail.javamail.MimeMessageHelper;

import com.autonavi.constants.Constant;

public class EmailUtils {

private static final Logger logger = LoggerFactory.getLogger(EmailUtils.class);

public static boolean sendHtmlMail(String subject,String content,String receiver){

boolean result = true;

try{

JavaMailSenderImpl senderImpl = new JavaMailSenderImpl();

// 设定mail server

senderImpl.setHost("smtp.abcdefg.com");

senderImpl.setPort(345);

senderImpl.setUsername(Constant.email); // 根据自己的情况,设置发件邮箱地址

senderImpl.setPassword(Constant.email_password); // 根据自己的情况, 设置password

senderImpl.setDefaultEncoding("UTF-8");

Properties prop = new Properties();

prop.put("mail.smtp.auth", "true"); // 将这个参数设为true，让服务器进行认证,认证用户名和密码是否正确

prop.put("mail.smtp.ssl.enable", "true");

prop.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");

senderImpl.setJavaMailProperties(prop);

// 建立邮件消息,发送简单邮件和html邮件的区别

MimeMessage mailMessage = senderImpl.createMimeMessage();

MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage);

// 设置收件人，寄件人

messageHelper.setTo(receiver);

messageHelper.setFrom(Constant.email);

messageHelper.setSubject(subject);

// true 表示启动HTML格式的邮件

messageHelper.setText(content,true);

// 发送邮件

senderImpl.send(mailMessage);

} catch (MessagingException e) {

// TODO Auto-generated catch block

result = false;

logger.info("EmailUtils.method [sendHtmlMail]: email send result-" + result +",error message-" + e);

}

return result;

}

以上设置中，有几个点需要注意：
