springboot邮件服务


1.添加jar包
<dependencies>
	<dependency> 
	    <groupId>org.springframework.boot</groupId>
	    <artifactId>spring-boot-starter-mail</artifactId> </dependency> </dependencies>


2.配置密码地址等信息(注：本demo以qq邮箱为例，各个邮箱配置方式有些许不同)
#邮件服务器地址
spring.mail.host=smtp.qq.com
# 端口号 qq邮箱需要使用SSL 端口号465或587
spring.mail.port=587
#邮箱(改为自己的邮箱地址)
[email protected]
#授权码(改为自己的授权码)
spring.mail.password=aaaaaaaaaaaaaaaa
spring.mail.default-encoding=UTF-8
#发送地址(与上面的邮箱地址相同)
[email protected]

3.mailService

@Component
public class MailServiceImpl implements MailService{ private final Logger logger = LoggerFactory.getLogger(this.getClass()); @Autowired private JavaMailSender mailSender; @Value("${mail.fromMail.addr}") private String from; @Override public void sendSimpleMail(String to, String subject, String content) { SimpleMailMessage message = new SimpleMailMessage(); message.setFrom(from); message.setTo(to); message.setSubject(subject); message.setText(content); try { mailSender.send(message); logger.info("简单邮件已经发送。"); } catch (Exception e) { logger.error("发送简单邮件时发生异常！", e); } } }

4.测试类
@RunWith(SpringRunner.class) @SpringBootTest public class MailServiceTest { @Autowired private MailService MailService; @Test public void testSimpleMail() throws Exception { MailService.sendSimpleMail("[email protected]","test simple mail"," hello this is simple mail"); } }

5.常见错误及可能原因：

Caused by: javax.mail.AuthenticationFailedException: 530 Error: A secure connection is requiered(such as ssl). More information at http://service.mail.qq.com/cgi-bin/help?id=28

--未指定端口spring.mail.port=587

Caused by: com.sun.mail.smtp.SMTPSenderFailedException: 501 mail from address must be same as authorization user

--发送地址需要和配置的邮箱名称一致

Caused by: javax.mail.AuthenticationFailedException: 535 Error: ÇëÊ¹ÓÃÊÚÈ¨ÂëµÇÂ¼¡£ÏêÇéÇë¿´: http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256

--授权码不正确

获取qq邮箱授权码方式

登录qq邮箱，进入设置--账户，开启POP3/SMTP服务，根据提示信息操作即可获取授权码
