Spring #12 : 이메일 기능 (230131)

이메일로 로그인 확인하는 기능!!

 

- 스프링에선 이메일 라이브러리를 이용해 쉽게 이메일 기능을 구현 가능

- 구글의 SMTP 서버을 이용해서 이메일 기능 구현

 

- pom.xml 파일에서 이메일 기능을 사용하기 위해 코어 스프링 라이브러리 버전을 4.1.1.RELEASE로 변경해야 한다.

		<!-- 이메일 -->
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-context-support</artifactId>
			<version>${org.springframework-version}</version>
		</dependency>
		<dependency>
			<groupId>javax.mail</groupId>
			<artifactId>javax.mail-api</artifactId>
			<version>1.5.4</version>
		</dependency>
		<dependency>
			<groupId>com.sun.mail</groupId>
			<artifactId>javax.mail</artifactId>
			<version>1.5.3</version>
		</dependency>

pom.xml에 들어가는 dependency태그 (관련 라이브러리 추가)

 

- host는 smtp를 사용

 

- 네이버 메일로 들어가 로그인 한 후, 환경설정

환경설정으로 들어가기

POP3/IMAP설정- IMAP/SMTP설정 - 사용함 체크 - 저장

pom.xml

스프링 라이브러리 버전을 4.1.1.RELEASE로 변경

라이브러리 태그 추가

 

...
<!--The definition of the Root Spring Container shared by all Servlets and Filters-->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/spring/*.xml</param-value>
	</context-param>
...

web.xml

설정 파일이 여러 개인 경우 톰캣 컨테이너 실행 시

spring폴더 안의 모든 설정파일을 읽도록 태그 추가

mail-context.xml

property의 host와 port는 위의 네이버 메일 환경설정으로 들어가서

해당 정보를 복사-붙여넣기로 하면 된다.

물결로 된 부분은 본인의 진짜 메일과 비밀번호!

}

package com.spring.promvn04.ex03;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.beans.factory.annotation.Autowired;

		request.setCharacterEncoding("utf-8");
		response.setContentType("text/html; charset=utf-8");
		PrintWriter out = response.getWriter();
		mailService.sendMail("~~~~~~~@naver.com", "testMail", "안녕하세요");
		mailService.sendPreConfiguredMail("test Mail sending");
		out.print("메일을 보냈습니다.");
	}
}

MailController.java

 

 

-- 결과 --

서버 실행 후, localhost:8080/promvn04/sendMail.do로 요청

 

이렇게 메일이 2개 온 것을 확인할 수 있다.

나머지는 동일하되, MailController와 MailService를 변경해주면 된다.

MailController.java

 

 

-- 결과 --

사진을 클릭하면 티스토리로,

블로그보기 하이퍼링크를 클릭하면 블로그로 사이트 이동이 된다.

따로 이미지를 넣어보았다.
