MailService 수정
📝 개요
MailService를 수정하였습니다.
⚙️ 구현 내용
기존에 메일을 전송하는 템플릿을 받을 때
String htmlContent = Files.readString(resource.getFile().toPath(), StandardCharsets.UTF_8);와 같이 했지만resource.getFile()은 일부 환경 (JAR로 빌드된 배포 환경)에서 FileNotFoundException이 발생할 수 있다.
따라서
String htmlContent = new String(resource.getInputStream().readAllBytes(), StandardCharsets.UTF_8);와 같은 방식으로 수정함.
