JPA save()方法插入数据成功后，返回值对象中一个字段默认值返回为null

[上虞区张学友]

实体类如下

package com.hzzh.mybook.book.model;

import org.hibernate.annotations.DynamicInsert;
import org.hibernate.annotations.DynamicUpdate;

import javax.persistence.*;

@DynamicUpdate
@DynamicInsert
@Entity
@Table(name = "mybooks")
public class book {
    @Id
    @GeneratedValue
    @Column(name = "GUID")
    Integer id;
    @Column(name = "BOOK_NAME")
    String bookName;
    @Column(name = "TYPE_")
    String type;
    @Column(name = "LIST_NAME")
    String listName;
    @Column(name = "USER_NAME")
    String userName;
    @Column(name = "PICTURE_URL")
    String pictureUrl;
    @Column(name = "shot")
    Integer shot;

    public void setShot(Integer shot) {
        this.shot = shot;
    }

    public Integer getShot() {
        return shot;
    }

    public void setType(String type) {
        this.type = type;
    }

    public void setBookName(String bookName) {
        this.bookName = bookName;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getType() {
        return type;
    }

    public String getBookName() {
        return bookName;
    }

    public Integer getId() {
        return id;
    }

    public String getListName() {
        return listName;
    }

    public String getPictureUrl() {
        return pictureUrl;
    }

    public String getUserName() {
        return userName;
    }

    public void setListName(String listName) {
        this.listName = listName;
    }

    public void setPictureUrl(String pictureUrl) {
        this.pictureUrl = pictureUrl;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }
}

Service实现类

  @Override
    public book save(book book) {
        return myBooksRepository.save(book);
    }

输入参数


返回后参数


实际传入后数据库数据


这里可以看到我数据已经传到数据库并写入了，也成功返回，但返回值中shot却为null，实际数据库是默认值1000。
shot字段我是设置了默认值。

有人吗 来大佬啊

已找到原因，因为缓存原因，数据库数据没更新到实体类中，用entityManager.refresh(Entity)方法更新下就好
