Springboot项目实现各种邮件发送

有时在开发中我们可能会需要对用户邮箱进行验证，这个时候就需要发送邮箱验证了，这里使用 springboot实现邮件发送。 1.先在Spring Boot的工程中的pom.xml中引入spring-boot-starter-mail依赖：

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency>

2.在完成依赖引入后，可在application.yml中添加配置属性内容。

spring: mail: host: smtp.qq.com username: xxxxxx password: xxxxxxx port: 25 protocol: smtp default-encoding: UTF-8

3.接下来就可以创建一个工具类来实现发送各种邮件。

import java.io.File; import java.util.Date; import java.util.Properties; import javax.mail.Authenticator; import javax.mail.MessagingException; import javax.mail.PasswordAuthentication; import javax.mail.Session; import javax.mail.Message.RecipientType; import javax.mail.internet.AddressException; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.core.io.FileSystemResource; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.mail.javamail.JavaMailSenderImpl; import org.springframework.mail.javamail.MimeMessageHelper; import org.springframework.stereotype.Component; import lombok.extern.log4j.Log4j2; @Component @Log4j2 public class MailSendUtil { @Autowired JavaMailSender javaMailSenderImpl; /** * 发送简单html文本的邮箱验证码 * @param to * @param code */ public boolean sendSimpleHtmlMail(String to,String code) { MimeMessage message=javaMailSenderImpl.createMimeMessage(); try { //设置发送人 message.setFrom(new InternetAddress(username)); //设置收件人 message.setRecipient(RecipientType.TO, new InternetAddress(to)); // 设置邮件标题 message.setSubject("邮箱验证码"); message.setContent("您正在对相关操作进行验证，非自我操作请忽略，验证码为：" + code + " 验证码十分钟内有效，请及时处理！","text/html;charset=UTF-8"); message.setSentDate(new Date()); javaMailSenderImpl.send(message); } catch (AddressException e) { log.error(e.getMessage()); return false; } catch (MessagingException e) { log.error(e.getMessage()); return false; } return true; } /** * 发送带图片的邮件 * @param to * @param subject * @param content * @param picPath * @param picId * @return */ public boolean sendPicMail(String to,String subject,String content,String picPath,String picId){ MimeMessage message=javaMailSenderImpl.createMimeMessage(); MimeMessageHelper helper=null; try { helper=new MimeMessageHelper(message, true); //设置发送人 message.setFrom(new InternetAddress(username)); //设置收件人 message.setRecipient(RecipientType.TO, new InternetAddress(to)); // 设置邮件标题 message.setSubject(subject); helper.setText(content, true); helper.addInline(picId, new FileSystemResource(new File(picPath))); // helper.setTo(new InternetAddress(to)); message.setSentDate(new Date()); javaMailSenderImpl.send(message); } catch (AddressException e) { log.error(e.getMessage()); return false; } catch (MessagingException e) { log.error(e.getMessage()); return false; } return true; } /** * 发送带附件的邮件 * @param to * @param subject * @param content * @param filePath * @return */ public boolean sendEnclosureMail(String to,String subject,String content,String filePath){ MimeMessage message=javaMailSenderImpl.createMimeMessage(); MimeMessageHelper helper=null; try { helper=new MimeMessageHelper(message, true); //设置发送人 message.setFrom(new InternetAddress(username)); //设置收件人 message.setRecipient(RecipientType.TO, new InternetAddress(to)); // 设置邮件标题 message.setSubject(subject); FileSystemResource file = new FileSystemResource(new File(filePath)); helper.addAttachment(file.getFilename(), file); message.setSentDate(new Date()); helper.setText(content, true); javaMailSenderImpl.send(message); } catch (AddressException e) { log.error(e.getMessage()); return false; } catch (MessagingException e) { log.error(e.getMessage()); return false; } return true; } /** * 发送带附件和图片的邮件 * @param to * @param subject * @param content * @param filePath * @return */ public boolean sendPicEnclosureMail(String to,String subject,String content,String filePath,String picPath,String picId){ MimeMessage message=javaMailSenderImpl.createMimeMessage(); MimeMessageHelper helper=null; try { helper=new MimeMessageHelper(message, true); //设置发送人 message.setFrom(new InternetAddress(username)); //设置收件人 message.setRecipient(RecipientType.TO, new InternetAddress(to)); // 设置邮件标题 message.setSubject(subject); FileSystemResource file = new FileSystemResource(new File(filePath)); //添加图片 helper.addInline(picId, new FileSystemResource(new File(picPath))); //添加附件 helper.addAttachment(file.getFilename(), file); message.setSentDate(new Date()); helper.setText(content, true); javaMailSenderImpl.send(message); } catch (AddressException e) { log.error(e.getMessage()); return false; } catch (MessagingException e) { log.error(e.getMessage()); return false; } return true; } }

springboot中使用JavaMailSender发送邮件可以说非常方便了。 4.最后可以通过简单的单元测试来发送邮件了。

import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.junit4.SpringRunner; import com.suntree.utils.MailSendUtil; @RunWith(SpringRunner.class) @SpringBootTest public class DemoApplicationTests { @Autowired MailSendUtil mailSendUtil; @Test public void sendMail(){ mailSendUtil.sendSimpleHtmlMail("153xxxxx@qq.com", "123456"); } }
