Я пытаюсь отправить электронное письмо, используя Spring Boot для этого, поэтому я создал учетную запись на mailtrap.io и добавил необходимую конфигурацию, как показано ниже
spring.mail.host=smtp.mailtrap.io
spring.mail.port=2525
spring.mail.username=0cfcf8adb32fea
spring.mail.password=20d3c0f7a44694
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
, затем я создалjava-файл конфигурации, подобный этому:
package com.example.databasedemo;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
@Component
public class Emailcfg {
@Value("${spring.mail.host}")
private String host;
@Value("${spring.mail.port}")
private int port;
@Value("${spring.mail.username}")
private String username;
@Value("${spring.mail.password}")
private String password;
public String getHost() {
return host;
}
public void setHost(String host) {
this.host = host;
}
public int getPort() {
return port;
}
public void setPort(int port) {
this.port = port;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
и контроллер Rest:
package com.example.databasedemo;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.*;
import javax.validation.ValidationException;
@RestController
@RequestMapping("/Mail")
public class mailController {
private Emailcfg emailCfg;
public mailController(Emailcfg emailCfg){
this.emailCfg = emailCfg;
}
@GetMapping
public void senddmail(){
// Create a mail sender
JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
mailSender.setHost(this.emailCfg.getHost());
mailSender.setPort(this.emailCfg.getPort());
mailSender.setUsername(this.emailCfg.getUsername());
mailSender.setPassword(this.emailCfg.getPassword());
// Create an email instance
SimpleMailMessage mailMessage = new SimpleMailMessage();
mailMessage.setFrom("elahidri.eh@gmail.com");
mailMessage.setTo("elahidri.eh@gmail.com");
mailMessage.setSubject("mail");
mailMessage.setText("this is a mail test ");
// Send mail
mailSender.send(mailMessage);
}
}
, когда я пытался его выполнить, я не получил ошибку, но не получил письмо, даже бросилнашел письмо в почтовом ящике mailtrap.io ОБНОВЛЕНИЕ это сообщение, которое я получил при отладке:
