[Tistory] 이메일 인증 보내기 테스트 샘플링

Could not autowire. No beans of 'JavaMailSender' type found

💡

yml에 문제 없는 것 같은데...?

💡

dev에만 메일 설정해서 그렇다나봄. 쓰는데 지장은 없다. (활성화되면 JavaMailSender 빈이 정상적으로 생성됨)

1. yml 설정

[application-dev.yml]

server:
  servlet:
    session:
      tracking-modes: cookie
    encoding:
      charset: utf-8
      force: true
  port: 8080

spring:
  mail:
    host: smtp.gmail.com
    port: 587
    username: compilemate@gmail.com
    password: your-app-password
    properties:
      mail:
        smtp:
          starttls:
            enable: true
            required: true
          auth: true

[application.properties]

spring.mail.host=smtp.gmail.com
spring.mail.port=587
spring.mail.username=compilemate@gmail.com
spring.mail.password=your-app-password
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
spring.mail.properties.mail.smtp.auth=true

2. EmailController

package com.example.emailtest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import lombok.RequiredArgsConstructor;

@RequiredArgsConstructor
@RestController
public class EmailController {

    private final EmailUtil emailUtil;

    @GetMapping("/sendmail")
    public String sendMail() {
        emailUtil.sendEmail("compilemate@gmail.com", "[Tistory 인증메일]", "되는지 테스트 하는 거예요");
        return "메일 잘 보내졌어";
    }
}

3. EmailUtil

package com.example.emailtest;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Component;

import lombok.RequiredArgsConstructor;

@RequiredArgsConstructor
@Component
public class EmailUtil {

    private final JavaMailSender sender; 

    // 메일 전송하는 메소드
    public void sendEmail(String toAddress, String subject, String body) {

        MimeMessage message = sender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(message);

        String htmlContent = getCertificationMessage(body);

        try {
            // 어디로 메일 보낼거냐
            helper.setTo(toAddress);
            // 제목이 무엇이냐
            helper.setSubject(subject);
            // true로 하면 html 디자인 되어있는 콘텐트를 넣어준다
            helper.setText(htmlContent, true);

        } catch (MessagingException e) {
            e.printStackTrace();
        }

        // 내가 설정한 이메일로 날아감
        sender.send(message);

    }


		//html 꾸미기
    private String getCertificationMessage(String body) {

        String certificationMessage = "";
        certificationMessage += "<h1 style='text-align: center;'>[Tistory 인증메일]</h1>";
        certificationMessage += "<h3 style='text-align: center;'>" +
                "인증코드 : <strong style='font-size: 32px; letter-spacing: 8px;'>" + body + "</strong></h3>";

        return certificationMessage;
    }

}

HTML 꾸며서 받기

    private String getCertificationMessage(String certificationNumber) {

        String certificationMessage = "";
        certificationMessage += "<h1 style='text-align: center;'>[Tistory 인증메일]</h1>";
        certificationMessage += "<h3 style='text-align: center;'>" +
                "인증코드 : <strong style='font-size: 32px; letter-spacing: 8px;'>" + certificationNumber + "</strong></h3>";

        return certificationMessage;
    }

💡

true라고 넣으면 html을 적용 할 수 있다.

4. http://localhost:8080/sendmail 주소로 요청
