Class YearMonthJavaType

java.lang.Object
org.hibernate.type.descriptor.java.AbstractClassJavaType<YearMonth>
io.leandev.appfuse.internal.jpa.YearMonthJavaType
All Implemented Interfaces:
Serializable, org.hibernate.type.descriptor.java.BasicJavaType<YearMonth>, org.hibernate.type.descriptor.java.JavaType<YearMonth>
public final class YearMonthJavaType extends org.hibernate.type.descriptor.java.AbstractClassJavaType<YearMonth>

YearMonth 的 Hibernate 基本型別映射：以 ISO 8601 YYYY-MM 字串存成 VARCHAR(7)。

Hibernate 沒有內建 YearMonth 映射，未處理時會退回 Java 序列化存成二進位欄位， 無法以 SQL 比較或排序。YYYY-MM 與 JSON wire format 一致，且字典序等於時間序， 區間查詢與排序可直接在資料庫進行。

刻意不用 JPA @Converter(autoApply = true)：converter 會被應用的 entity scan 掃到， 與框架自動註冊重複時 Hibernate 拒絕啟動；JavaType 不參與 entity scan。
