java - Spring jpa 在返回实体对象时更改实体 boolean 变量名称

Question

我有以下 Comment 实体:

@Entity
@Table(name = "comment")
public class Comment extends AbstractEntity 

还有其中一列:

@Column(name = "is_deleted")
    private Boolean isDeleted;

返回的注释对象将变量名从 isDeleted 更改为 deleted。

当我从客户端调用中保存 Comment 对象时。如果我说 isDeleted:false，我得到的是 deleted:null。如果我说 deleted:false，我得到的是 deleted:false。所以看起来列名已删除但不是 isDeleted。

不知道为什么会这样。

整个评论实体代码:

package no.nsd.archivingportal.domain.comment;

import no.nsd.archivingportal.domain.AbstractEntity;
import no.nsd.archivingportal.domain.user.User;
import org.hibernate.annotations.Type;

import javax.persistence.*;
import java.util.UUID;

@Entity
@Table(name = "comment")
public class Comment extends AbstractEntity {

    @Type(type="pg-uuid")
    @Column(name = "commented_entity")
    private UUID commentedEntity;

    @ManyToOne
    @JoinColumn(name = "user_id")
    private User author;

    @Column(name = "content")
    private String content;

    @Column(name = "is_deleted")
    private Boolean isDeleted;

    public UUID getCommentedEntity() {
        return commentedEntity;
    }

    public void setCommentedEntity(UUID commentedEntity) {
        this.commentedEntity = commentedEntity;
    }

    public User getAuthor() {
        return author;
    }

    public void setAuthor(User author) {
        this.author = author;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

    public Boolean getDeleted() {
        return isDeleted;
    }

    public void setDeleted(Boolean deleted) {
        isDeleted = deleted;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        if (!super.equals(o)) return false;

        Comment comment = (Comment) o;

        if (commentedEntity != null ? !commentedEntity.equals(comment.commentedEntity) : comment.commentedEntity != null)
            return false;
        if (author != null ? !author.equals(comment.author) : comment.author != null) return false;
        if (content != null ? !content.equals(comment.content) : comment.content != null) return false;
        return isDeleted != null ? isDeleted.equals(comment.isDeleted) : comment.isDeleted == null;

    }

    @Override
    public int hashCode() {
        int result = super.hashCode();
        result = 31 * result + (commentedEntity != null ? commentedEntity.hashCode() : 0);
        result = 31 * result + (content != null ? content.hashCode() : 0);
        result = 31 * result + (isDeleted != null ? isDeleted.hashCode() : 0);
        return result;
    }

    @Override
    public String toString() {
        return "Comment{" +
                "commentedEntity=" + commentedEntity +
                ", author=" + author +
                ", content='" + content + '\'' +
                ", isDeleted=" + isDeleted +
                '}';
    }
}

我认为问题出在 isDeleted 属性的 getter/setter 上。

因此，要么将属性名称更改为 deleted 并保持您的 getter/setter 不变，要么更改您的 getter/setter 以更准确地反射(reflect)属性的名称例如

public Boolean getIsDeleted() {
    return isDeleted;
}

public void setIsDeleted(Boolean deleted) {
    isDeleted = deleted;
}
