两个实体之间的特定关系

Question

请帮助我设计 Spring Boot 应用程序的架构。我想创建一个字典，在其中可以放置一些带有转录、翻译和同义词集的单词。所以问题是：我有一个单词实体，每个单词都可以有一组同义词，但我无法理解如何在单词和同义词之间创建关系，因为同义词本身也是一个单词。我无法在 Word 实体中定义 Set 同义词。那么我该如何实施呢？ 我尝试过，但我知道这是愚蠢的方式：

@Table(name = "Word")
public class Word {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private int id;
    @NotBlank(message = "You should add some word here!")
    @Column(name = "spelling")
    private String spelling;
    @Column(name = "transcription")
    private String transcription;
    @NotBlank(message = "You should add translation here!")
    @Column(name = "translation")
    private String translation;
    @ManyToOne
    @JoinColumn(name = "synonyms_id", referencedColumnName = "id")
    private Synonyms synonyms;
    @ManyToOne
    @JoinColumn(name = "dictionary_id", referencedColumnName = "id")
    private Dictionary dictionary;

@Table(name = "Synonyms")
public class Synonyms {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private int id;
    @OneToMany(mappedBy = "synonyms", fetch = FetchType.LAZY)
    private Set<Word> words;

Answer 1

I think according to your use-case if a word is also a synonymsthen you don't need another entity to make relationship
        and you can create a many to many relationship means a word can be associated with synonyms and also a word can be synonyms of other words just like this

@ManyToMany
        @JoinTable(
            name = "word_synonyms", 
            joinColumns = @JoinColumn(name = "word_id"), 
            inverseJoinColumns = @JoinColumn(name = "synonym_id")
        )
     private Set<Word> synonyms = new HashSet<>();

     @ManyToMany(mappedBy = "synonyms")
     private Set<Word> synonymousOf = new HashSet<>();
