An entity may contain some properties like id etc that I think no need to show in Frontend, so I turn to DTO that only holds the property I think useful. For example, the Article and ArticleDTO, here is the code.
Article.class
@Entity
public class Article implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String title;
private String subtitle1;
private String subtitle2;
...
private List<Block> blocks;
}
ArticleDTO.class
public class ArticleDTO implements Serializable {
private Long[] categoryIds;
private String[] keywords;
private String title;
private String subtitle1;
private String subtitle2;
...
private List<BlockDTO> blockDTOs;
}
And my question is that can I own these two properties (categoryIds and keywords) in my DTO? Because I think my Frontend will return the JSON like this:
{
"categoryIds": [
1,
2
],
"keywords": [
"amazing",
"incredible",
"easy"
],
"title": "Shock! A student from ZJNU.....",
"subtitle1": "subTitle1",
"subtitle2": "subTitle2",
...
}
If I shouldn't do this, what's the right approach? And if I can do this, could you please also tell me what's the best way to mapper my ArticleDTO to Article? Thank you so much!
