pom需要引入spring-boot-starter-mail
如下:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency>
我这里用的是126邮箱 163应该是同理的
配置文件 application.properties
端口设置为465、开启ssl协议类型为smtp (在阿里云部署需要配置出入规则的465端口。我是把出和入的端口都打开了)按照这个配置是能在阿里云调用通的
我刚开始没有配置 端口设置为465、开启ssl、协议类型为smtp 在本地可以调通能发邮件,到阿里云服务器不行
#我用的是126邮箱
spring.mail.host=smtp.126.com
#这里配置你的邮箱 spring.mail.username=nideyouxiang@126.com spring.mail.password=开启smtp时候的授权码 spring.mail.properties.mail.smtp.auth=true spring.mail.properties.mail.starttls.enable=true spring.mail.properties.mail.starttls.required=true spring.mail.properties.mail.smtp.port=465 spring.mail.protocol=smtp spring.mail.properties.mail.smtp.ssl.enable=true

上边pom的spring-boot-starter-mail引入后你能使用
JavaMailSender 是mail包提供的
import java.io.File; import javax.mail.MessagingException; import javax.mail.internet.MimeMessage; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.core.io.FileSystemResource; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.mail.javamail.MimeMessageHelper; import org.springframework.stereotype.Service; import sinosoft.core.exception.ServiceException; import sinosoft.sys.modular.user.enums.SysUserExceptionEnum; @Service public class MailService { private final Logger logger = LoggerFactory.getLogger(this.getClass()); @Autowired private JavaMailSender sender; @Value("${spring.mail.username}") private String formMail; /** * 发送简单的邮件信息 * @param toMail * @param subject * @param content */ public void sendSimpleMail(String toMail,String subject,String content) { SimpleMailMessage simpleMailMessage = new SimpleMailMessage(); simpleMailMessage.setFrom(formMail); simpleMailMessage.setTo(toMail); simpleMailMessage.setSubject(subject); simpleMailMessage.setText(content); try { sender.send(simpleMailMessage); logger.info("发送给"+toMail+"邮件已经发送。 subject:"+subject); } catch (Exception e) { logger.info("发送给"+toMail+"send mail error subject:"+subject); e.printStackTrace(); } } /** * 发送html格式的邮件 * @param toMail * @param subject * @param content */ public void sendHtmlMail(String toMail,String subject,String content) { MimeMessage createMimeMessage = sender.createMimeMessage(); try { //true表示需要创建一个multipart message 如何不设置就不会解析html MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(createMimeMessage,true); mimeMessageHelper.setFrom(formMail); mimeMessageHelper.setTo(toMail); mimeMessageHelper.setSubject(subject); mimeMessageHelper.setText(content, true); sender.send(createMimeMessage); logger.info("发送给"+toMail+"html邮件已经发送。 subject:"+subject); } catch (MessagingException e) { logger.info("发送给"+toMail+"html send mail error subject:"+subject); e.printStackTrace(); } } public void sendAttachmentsMail(String toMail,String subject,String content,String filePath) { MimeMessage message = sender.createMimeMessage(); try { MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setFrom(formMail); helper.setTo(toMail); helper.setSubject(subject); helper.setText(content, true); FileSystemResource file = new FileSystemResource(new File(filePath)); String fileName = filePath.substring(filePath.lastIndexOf("/")); helper.addAttachment(fileName, file); sender.send(message); logger.info("发送给"+toMail+"带附件的邮件已经发送。"); } catch (MessagingException e) { e.printStackTrace(); logger.error("发送给"+toMail+"带附件的邮件时发生异常!", e); } } }
然后你就可以在你的业务代码中调上边封装的MailService了
比如发送简单的邮件消息(我的业务代码):
/** * 邮件服务 */ @Resource private MailService mailService; //toEmail-要发送的邮箱、systemName-邮件的标题、content-邮件的内容 mailService.sendSimpleMail(toEmail, systemName, content);
