org.springframework.beans.factory.BeanCreationException 与系统语言

Question

当我启动一个 spring boot 应用程序时，当我使用土耳其语系统语言时出现这个异常。但是，如果我更改为英文系统语言，spring boot 应用程序可以正常工作。我无法提供有关该问题的更多详细信息，因为更改系统语言就足够了。但我想继续使用土耳其语系统语言。

如果需要任何信息，我愿意分享。

• 操作系统：macOS 12.1
• java:jdk11

Answer 1

堆栈跟踪表明BeanCreationException 的根本原因是在尝试将某些内容转换为enum 值时失败。此外，在尝试反序列化（“再水合”）从数据库中检索到的数据时，似乎正在发生这种情况。

此外，消息文本暗示您已将枚举值 OldTradeType.DAİLY_RENT 存储在数据库中。 stacktrace 说 Hibernate 无法反序列化，因为反序列化器目前无法识别特定的枚举值。

这是我的理论。

1. 您的本地化方案包括使用 OldTradeType 枚举的不同变体，其值取决于系统区域设置；即“系统语言”。 （我不知道如何......但不知何故。）

2. 当区域设置为英语时，您已经创建并存储了对象。

3. 您现在已更改语言环境

4. 语言环境更改意味着您的应用当前使用的 thd OldTradeType 枚举版本不再与序列化时使用的版本兼容。所以它抛出一个异常，因为它不能反序列化它。

---

如果这是正确的，有几种方法可以解决这个问题。

1. 更改表示枚举值的方式，以便内存中的 enum 类型不依赖于语言环境设置。

2. 更改枚举转换器类，以便将特定于语言环境的内存中枚举映射到本地独立表示。

3. 更改枚举转换器类，使其了解数据库中所有可能的特定于语言环境的表示...并在反序列化时映射到适当的表示。

4. 当您切换系统时，系统区域设置会重置数据库；即丢弃所有数据。

我不能告诉你哪个更合适。这取决于您的应用程序。

这发生在 bean 创建期间，但这不是问题的原因。问题出在您的代码¹ 而不是 SpringBoot 或 Hibernate。

^{1 - 或者如果 com.sample 类是示例代码......问题是您使用示例的方式并非旨在应对。}
