Java 软删除指令休眠

我有一个插件类。删除其实体时，我希望将记录保留在数据库中，但将其隐藏在查询中

在以下实现中，我遇到了一个异常：

@Entity
@SQLDelete(sql = "UPDATE addon SET active IS FALSE WHERE id = ?")
@Where(clause = "active = false")
public class Addon {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;
    @ManyToOne
    private Category category;
    private String name;
    private int amount;
    private int minimalAmount;
    @OneToMany
    private Set<HandOver> handOvers;
    private boolean active;

    public Addon(){
         this.setAmount(0);
         this.active = true;
    }

    @PreRemove
    public void deleteAddon() {
        this.setActive(false);
    }
}

例外情况：

@Entity
@SQLDelete(sql = "UPDATE addon SET active IS FALSE WHERE id = ?")
@Where(clause = "active = false")
public class Addon {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;

    private String name;
    private int amount;
    private int minimalAmount;
    @OneToMany
    private Set<HandOver> handOvers;
    private boolean active;

    public Addon(){
         this.setAmount(0);
         this.active = true;
    }

    @PreRemove
    public void deleteAddon() {
        this.setActive(false);
    }
}

查询（hibernate配置中的“show_sql”=true）为：

---

我使用的是Hibernate 5和MySQL 8。

试着这样写：@Where（clause=“active='false'），或者如果active=true意味着一个可访问的记录，则为true；）

我想说它应该是

active IS FALSE

而不是

active FALSE

和

SET active=FALSE

（true literal）而不是

SET active='FALSE'

（字符串值“FALSE”，尽管MySQL很可能能够正确地转换）。仍然会引发相同的异常。您可以发布生成的SQL吗？它应该作为DEBUG for

org.hibernate.SQL

记录。顺便说一句，如果你想过滤非活动的插件，我想进一步说where子句应该是

active，它是TRUE

。程序更进一步，但随后引发了另一个异常。我已经在问题中添加了异常和查询。为什么会出现这样的查询：“UPDATE addon SET active IS FALSE，其中id=？”应该是：“UPDATE addon SET active=FALSE，其中id=？”，所以写下以下内容：@SQLDelete（sql=“UPDATE addon SET active=FALSE，其中id=？”）
