Spring MVC 5.xx 프레임워크를 사용하여 이메일을 보내는 간단한 방법 – org.springframework.mail. javamail.JavaMailSenderImpl
게시 됨: 2018-10-23
Spring MVC 프레임워크 소개, Hello World Spring MVC, Spring MVC를 사용하여 여러 파일 업로드 등과 같은 Spring MVC의 Crunchify에 대해 읽었을 수 있는 기사가 꽤 있습니다.
이 튜토리얼에서는 Spring MVC 5.1.3.RELEASE를 사용하여 이메일을 보내기 위해 org.springframework.mail.javamail.JavaMailSenderImpl 라이브러리를 활용하는 방법을 다룰 것입니다.
시작하자:
다음은 최종 프로젝트 구조입니다. 그에 따라 파일을 생성해야 합니다.
1 단계
간단한 Maven 프로젝트 CrunchifySpringMVC4SendEmailTutorial 을 만듭니다.
- "
Create a simple project (skip archetype selection)" 옵션에 대한 확인란을 선택합니다. - 다음 단계에서 사용할 그룹 ID, 아티팩트 ID, 이름 및 설명과 같이 아래 다이어그램과 유사한 모든 정보를 제공하십시오.
2 단계
pom.xml 파일을 열고 3개의 종속성을 추가합니다.
- 스프링 컨텍스트
- 스프링 컨텍스트 지원
- javax.mail
여기 내 전체 pom.xml 파일이 있습니다.

3단계
src/main/resources 폴더에 Spring Bean 파일 crunchify-bean.xml 을 생성합니다.
Spring Bean은 전통적인 XML 접근 방식을 사용하여 구성됩니다. Spring MVC 프레임워크에서 bean 은 instantiated , assembled 및 Spring IoC(Inversion of Control) 컨테이너에 의해 managed 되는 객체입니다.

username 및 password 필드 값을 실제/실제 값으로 업데이트했는지 확인하십시오.
4단계
src/main/java 폴더 아래 @Service (org.springframework.stereotype.Service)로 API 클래스 CrunchifyEmailAPI.java 주석을 생성합니다.

5단계
src/main/java 폴더 아래에 테스트 클래스 CrunchifyEmailTest.java 를 생성합니다.

ClassPathXmlApplicationContext ; /** * @author Crunchify.com * */ public class CrunchifyEmailTest { @SuppressWarnings ( "resource" ) public static void main ( String args [ ] ) { // Spring Bean file you specified in /src/main/resources folder String crunchifyConfFile = "crunchify-bean.xml" ; ConfigurableApplicationContext context = new ClassPathXmlApplicationContext ( crunchifyConfFile ) ; // @Service("crunchifyEmail") <-- same annotation you specified in CrunchifyEmailAPI.java CrunchifyEmailAPI crunchifyEmailAPI = ( CrunchifyEmailAPI ) context . getBean ( "crunchifyEmail" ) ; // email subject String subject = "Hey..

Let's understand details on how Spring MVC works -- By Crunchify Admin" ; crunchifyEmailAPI . crunchifyReadyToSendEmail ( toAddr , fromAddr , subject , body ) ; } } |
위의 toAddr 및 fromAddr 을 업데이트했는지 확인하십시오.
