我正在尝试在我的项目中使用javax邮件。我在gmail中启用了安全性较低的应用,并制定了入站规则来解锁端口465。
这是我在应用程序属性中使用的配置。
'''
spring.mail.host=smtp.hmail.com
spring.mail.username=dumitrachesabin@gmail.com
spring.mail.password=mypass
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.socketFactory.port=465
spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.smtp.socketFactory.fallback=false
support.email=dumitrachesabin@gmail.com
'''
我在网上发现465端口需要解锁,并找到了一个快速指南,该操作可以在照片中看到。
在控制器类中,我在用户引入他的注册凭证(用户名,电子邮件地址)以生成带有链接到编辑配置文件页面的电子邮件之后设置。
当我输入用户名和邮件并单击提交时,出现错误“未知的SMTP主机:smtp.hmail.com;”, 但是数据已发送到数据库。我在网页上收到错误500。
@RequestMapping(value = "/newUser", method = RequestMethod.POST)
public String newUserPost(HttpServletRequest request,
@ModelAttribute("email") String userEmail,
@ModelAttribute("username") String username, Model model) throws Exception {
model.addAttribute("classActiveNewAccount", true);
model.addAttribute("email", userEmail);
model.addAttribute("username", username);
if (userService.findByUsername(username) != null) {
model.addAttribute("usernameExists", true);
return "myAccount";
}
if (userService.findByEmail(userEmail) != null) {
model.addAttribute("email", true);
return "myAccount";
}
User user = new User();
user.setUsername(username);
user.setEmail(userEmail);
String password = SecurityUtility.randomPassword();
String encryptedPassword = SecurityUtility.passowrdEncoder().encode(password);
user.setPassword(encryptedPassword);
Role role = new Role();
role.setRoleId(1);
role.setName("ROLE_USER");
Set<UserRole> userRoles = new HashSet<>();
userRoles.add(new UserRole(user, role));
userService.createUser(user, userRoles);
String token = UUID.randomUUID().toString();
userService.createPasswordResetTokenForUser(user, token);
String appUrl = "http://"+ request.getServerName() + ":" + request.getServerPort() + request.getContextPath();
SimpleMailMessage email = mailConstructor.constructResetTokenEmail(appUrl, request.getLocale(), token, user,
password);
mailSender.send(email);
model.addAttribute("emailSent", true);
return "myAccount";
这里有邮件构造函数类。
@Component
public class MailConstructor {
@Autowired
private Environment env;
public SimpleMailMessage constructResetTokenEmail(
String contextPath, Locale locale, String token, User user,
String password) {
String url = contextPath + "/newUser?token=" + token;
String message = "\nPlease click on this link to verify your email and edit your personal information. Your password is:\n"
+ password;
SimpleMailMessage email = new SimpleMailMessage();
email.setTo(user.getEmail());
email.setSubject("Shop-Ufes - New User");
email.setText(url + message);
email.setFrom(env.getProperty("support.email"));
return email;
}
}
我进入控制台的错误是:
2020-10-03 16:57:22.256 ERROR 6952 --- [nio-8080-exec-7] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.MessagingException: Unknown SMTP host: smtp.hmail.com;

答案 0 :(得分:1)
您的设置似乎是有效的
spring.mail.host=smtp.hmail.com
似乎有一个与主机名有关的错字。我相信应该是
spring.mail.host=smtp.gmail.com
