Каково использование метода «Перевести» от веб -сайта в DB и наоборот в Spring Boot? ⇐ JAVA

[Anonymous]

Я запутался в этих методах в службе реализации. Требуется ли использовать эти методы? < /P>

Код: Выделить всё

private BlogEntity translateWebToDb(Blog blog) {
BlogEntity blogEntity = new BlogEntity();
blogEntity.setBlogId(blog.getBlogId());
blogEntity.setTitle(blog.getTitle());
blogEntity.setDescription(blog.getDescription());
blogEntity.setUpdatedAt(blog.getUpdated_at());

return blogEntity;
}

private Blog translateDbToWeb(BlogEntity blogEntity) {
return new Blog(
blogEntity.getBlogId(),
blogEntity.getTitle(),
blogEntity.getDescription(),
blogEntity.getCreatedAt(),
blogEntity.getUpdatedAt());
}
