用途:此文仅供,自己今后的小程序通过邮件,批量通知用户。
简单记录了一些发送基本邮件的操作。
项目(SpringBoot版本为2.1.2.RELEASE):
核心依赖(其他相关依赖,在其使用的地方具体说明):
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency>
application.yml——邮件发送相关配置:
spring: mail: host: smtp.qq.com username: ***@qq.com password: *** #qq邮箱开启POP3/SMTP服务后,生成的授权码 receiver: ***@qq.com protocol: smtp default-encoding: utf-8
邮件实体类(使用Lombok的注解简化实体构造):
import lombok.Data; import org.springframework.core.io.FileSystemResource; @Data public class MailBean { private String subject; private String text; private FileSystemResource file; private String attachmentFilename; private String contentId; }
简单封装邮件发送的工具类:
import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.mail.javamail.MimeMessageHelper; import org.springframework.stereotype.Component; import javax.mail.MessagingException; import javax.mail.internet.MimeMessage; @Component public class MailUtil { private final JavaMailSender mailSender; @Value("${spring.mail.username}") private String sender; @Value("${spring.mail.receiver}") private String receiver; @Autowired public MailUtil(JavaMailSender mailSender) { this.mailSender = mailSender; } public void sendMailSimple() { SimpleMailMessage mimeMessage = new SimpleMailMessage(); mimeMessage.setFrom(sender); mimeMessage.setTo(receiver); mimeMessage.setSubject("主题"); mimeMessage.setText("正文"); mailSender.send(mimeMessage); } private void sendMail(MailBean mailBean, boolean html, boolean multipart) { MimeMessage mimeMessage = mailSender.createMimeMessage(); try { MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, multipart); helper.setFrom(sender); helper.setTo(receiver); helper.setSubject(mailBean.getSubject()); helper.setText(mailBean.getText(), html); if (multipart) { helper.addAttachment(mailBean.getAttachmentFilename(), mailBean.getFile()); } } catch (MessagingException e) { e.printStackTrace(); } mailSender.send(mimeMessage); } public void sendMailText(MailBean mailBean) { sendMail(mailBean, false, false); } public void sendMailHtml(MailBean mailBean) { sendMail(mailBean, true, false); } public void sendMailAttachment(MailBean mailBean) { sendMail(mailBean, true, true); } public void sendMailInline(MailBean mailBean) { MimeMessage mimeMessage = mailSender.createMimeMessage(); MimeMessageHelper helper = new MimeMessageHelper(mimeMessage); try { helper.setFrom(sender); helper.setTo(receiver); helper.setSubject(mailBean.getSubject()); helper.setText(mailBean.getText(), true); helper.addInline(mailBean.getContentId(), mailBean.getFile()); } catch (MessagingException e) { e.printStackTrace(); } mailSender.send(mimeMessage); } }
单元测试就不写了,忘记了。发送测试:
import org.springframework.beans.factory.annotation.Autowired; import org.springframework.core.io.FileSystemResource; import org.springframework.util.ResourceUtils; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; import org.thymeleaf.TemplateEngine; import java.io.File; import java.io.IOException; @RestController public class MailController { private final MailUtil mailUtil; private final TemplateEngine templateEngine; @Autowired public MailController(MailUtil mailUtil, TemplateEngine templateEngine) { this.mailUtil = mailUtil; this.templateEngine = templateEngine; } @GetMapping("/simple") public void simple() { MailBean mailBean = new MailBean(); mailBean.setSubject("简单纯文本邮件测试"); mailBean.setText("内容"); mailUtil.sendMailText(mailBean); // mailUtil.sendMailSimple(); } @GetMapping("/html") public void html() { MailBean mailBean = new MailBean(); mailBean.setSubject("简单html代码,邮件测试"); mailBean.setText("<h1>表达个意思</h1>"); mailUtil.sendMailHtml(mailBean); } @GetMapping("/attachment") public void attachment() { String path = "classpath:反.jpg"; try { File file = ResourceUtils.getFile(path); FileSystemResource fileSystemResource = new FileSystemResource(file); MailBean mailBean = new MailBean(); mailBean.setSubject("主题"); mailBean.setText("内容"); mailBean.setAttachmentFilename(file.getName()); mailBean.setFile(fileSystemResource); mailUtil.sendMailAttachment(mailBean); } catch (IOException e) { e.printStackTrace(); } } }
