休眠MySQL

Question

假設我有這樣的POJO，我想插入文章到MySQL數據庫。

@Entity 
@Table(name = "article") 
public class Article{ 
    private String author; 
    private String body; 
    private int commentCount; 
    private List<EntryComment> comments; 


@Entity 
@Table(name = "comments") 
public class Comment{ 
    private String author; 
    private String body; 
    private int voteCount; 

我想從另一個表中刪除字段comments從「文章」。是否可以使用hibernate註釋將註釋放在單獨的表中？

Answer 1

當然是了。我建議你使用你已經@column爲字符串的所有元素註解和詮釋然而元素的意見只是看看代碼那裏：

文章類別：

@Entity 
@Table(name = "article") 
public class Article{ 
    private String author; 
    private String body; 
    private int commentCount; 

    @OneToMany(mappedBy = "article") 
    @LazyCollection(LazyCollectionOption.TRUE) 
    private List<EntryComment> comments; 

評論類：

@Entity 
@Table(name = "comments") 
public class Comment{ 

    @ManyToOne(fetch = FetchType.LAZY) 
    private Article article; 

    private String author; 
    private String body; 
    private int voteCount;
