我有一個自定義轉換器加載到加載JPA 2.1轉換爲UUID將其傳送到一個字符串,而不是一個二值:休眠失敗當與彈簧引導和彈簧數據JPA
package de.kaiserpfalzEdv.commons.jee.db;
import javax.persistence.AttributeConverter;
import javax.persistence.Converter;
import java.util.UUID;
@Converter(autoApply = true)
public class UUIDJPAConverter implements AttributeConverter<UUID, String> {
@Override
public String convertToDatabaseColumn(UUID attribute) {
return attribute.toString();
}
@Override
public UUID convertToEntityAttribute(String dbData) {
return UUID.fromString(dbData);
}
}
該轉換器(ⅰ有其他一些特別的時間/日期處理)駐留在庫.jar文件中。
然後我有一個.jar文件中的實體。像這樣:

}
@Override

if (obj == null) {
return false;
}
if (obj == this) {
return true;
}
if (obj.getClass() != getClass()) {
return false;
}
SecurityTicket rhs = (SecurityTicket) obj;
return new EqualsBuilder()
.append(this.id, rhs.id)
.isEquals();
}
@Override
public int hashCode() {
return new HashCodeBuilder()
.append(id)

}
@Override

}
}
當通過maven和testng運行集成測試時,數據庫工作得很好。但是,當我啓動應用程序(第三.jar文件),我得到一個討厭的例外,這可以歸結爲:

轉換的自動應用不起作用。我嘗試將轉換器註釋到類和屬性本身。但轉換器沒有使用。但是當我通過hibernate特定註釋hibernate添加hibernate UUID類型時,抱怨它不能爲同一個屬性提供轉換器和hibernate類型定義。所以hibernate讀取轉換器配置。
使用envers時,JPA 2.1轉換器不起作用。但我不使用我的軟件中的envers。
我希望有一個人在那裏誰知道我做錯了什麼......
JPA規範明確規定轉換不會應用於實體的id屬性。也許你可以刪除你的JPA轉換註釋,並使用Hibernate特定的方法來嘗試它? –
