java - 自动生成的索引名超过 MySQL 最大命名长度

Question

因此，我的表名大小相对较大，但距离 64 个字符的限制还很远。问题是，当我尝试为我的一个表创建索引时，Spring 自动生成的名称超过 64，因此由于创建索引时出现错误，我无法启动我的应用程序。

我已经尝试过：

• 手动设置索引名称：它不起作用，因为 Spring 不断为我的索引名称添加前缀（即，如果我将名称设置为“index_name”，Springs 将其更改为 table_name_class_name_more_classes_type_text_index_name ）；
• 自定义隐式命名策略：由于 Springs 不断添加前缀，它不起作用；
• 自定义物理命名策略：它不起作用，因为我将文本剪辑为 64 个字符时不断收到很多“找不到表”错误；

这里只是一个例子，大多数表的命名大小不同：

您可以使用自定义隐式命名策略来限制与此类似的字符数量：https ://github.com/hibernate/hibernate-orm/blob/main/hibernate-core/src/test/java/org/hibernate/测试/注释/命名策略/LongIdentifierNamingStrategy.java
