[SES] AWS Simple Email Service & Spring Boot(Kotlin)

SES 설정

1. AWS 설정

1. SES 자격 증명
   • 발신자 Email 입력 후 Email 인증
2. IAM
   • SES 사용키 발급 (access-key, secret-key)
   • 권한 : AmazonSESFullAccess

2. Spring Boot 설정

• Dependency
  • implementation("software.amazon.awssdk:sesv2:2.28.16")
    • implementation("com.amazonaws:aws-java-sdk-ses:1.12.773") // 조만간 지원 X
  • implementation("org.springframework.boot:spring-boot-starter-thymeleaf") // 메일의 Email 템플릿 사용시 필요
• Config
  • SesConfig 설정

@Bean 
fun sesV2Client():SesV2Client{ 
	val credentials = AwsBasicCredentials.create(accessKey, secretKey) 
    val provider = StaticCredentialsProvider.create(credentials) 
    
    return SesV2Client.builder() 
    		.credentialsProvider(provider) 
            .region( Region.AP_NORTHEAST_2 ) 
            .build(); 
} 

// thymeleaf 설정
@Bean 
fun setTemplateEngine(springResourceTemplateResolver:SpringResourceTemplateResolver): TemplateEngine { 
	val templateEngine = SpringTemplateEngine() 
    templateEngine.addTemplateResolver(springResourceTemplateResolver) 
    return templateEngine
}

        val destination: Destination = Destination.builder().toAddresses(toAddress).build()

        val sub = Content.builder().data(title).build()

        val content = Content.builder().data(contentHtml).build()
