因此，尽管我个人讨厌软删除，但我工作的项目中每个表都只能软删除。我不确定如何处理关联表上的软删除，其字段如下所示:
@ManyToMany(targetEntity = AdvertisementVendor.class, fetch = FetchType.EAGER)
@JoinTable(name = "advertisement_version_advertisement_vendor_association",
joinColumns = @JoinColumn(name = "advertisement_version_id"),
inverseJoinColumns = @JoinColumn(name = "advertisement_vendor_id"))
private Set<AdvertisementVendor> _advertisement_vendors = new HashSet<>();
我已经了解了如何做 soft deletes ，但我不确定如何将其应用到关联表。
更新:
采纳 Dragan Bozanovic 的建议，我将专栏更新为:
@ManyToMany(targetEntity = AdvertisementVendor.class, fetch = FetchType.EAGER)
@JoinTable(name = "advertisement_version_advertisement_vendor_association",
joinColumns = @JoinColumn(name = "advertisement_version_id"),
inverseJoinColumns = @JoinColumn(name = "advertisement_vendor_id"))
@WhereJoinTable(clause = "is_deleted = 0")
@SQLDelete(sql = "UPDATE advertisement_version_advertisement_vendor_association SET is_deleted = 1 WHERE advertisement_version_id = ? AND advertisement_vendor_id = ?", check = ResultCheckStyle.COUNT)
@SQLInsert(sql = "INSERT INTO advertisement_version_advertisement_vendor_association " +
"(advertisement_version_id, advertisement_vendor_id, is_deleted) VALUES(?, ?, 0) " +
"ON DUPLICATE KEY UPDATE is_deleted = 0")
private Set<AdvertisementVendor> _advertisement_vendors = new HashSet<>();
但这似乎不起作用。它似乎忽略了@SQLDelete并只是删除了映射。
更新2:
忽略第一次更新，它与不同的代码有关。上面的示例按原样运行。
最佳答案
您可以使用@WhereJoinTable用于过滤连接表上的条件:
Where clause to add to the collection join table. The clause is written in SQL. Just as with
Where, a common use case is for implementing soft-deletes.
