jpa - LocalDateTime 和 JodaDate 冲突

Question

我正在使用 spring MVC、hibernate、Spring Data JPA 项目创建一个多模块 Maven 项目。 目前我已经集成了 Activiti 工作流引擎并使用 Joda 日期依赖项。但我的模型类使用 java 8 LocalDateTime。 Spring Data JPA 审核(@CreatedDate、@LastModifiedDate，...)也在单独的 Maven 模块(common-service)中启用和配置

项目结构-

模型类 -

JPA 配置文件 -

<小时/>

我的问题是，当我保存工作流对象时，发生 Joda LocalDate not present 错误

除了 JPA 审核的创建日期和修改日期之外，没有其他日期字段

Answer 1

嗯，在那条巨大的堆栈跟踪中的某个地方有一段代码在“按名称”寻找 org.joda.time.LocalDate 类，而 JVM 找不到它。

定位问题的唯一方法是通过调试 - 我将从 GenericConversionService.getRequiredTypeInfo() 开始并搜索堆栈。

但是，关于您列出的模型类......

@CreatedDate 和 @LastModifiedDate 都使用(我假设是 Java 8 的)LocalDateTime，Spring Data Auditing 可能支持它。 ，但由于 LocalDateTime 缺乏唯一性信息(即时区)，因此可能有一些(Spring Framework)代码尝试将 LocalDateTime 转换为 Joda Time 。

应该使用全世界唯一的值进行审核。

使用您的模型和 the logic I provided on a similar issue 的示例... 如果印度(印度标准时间，GMT+5:30)的用户在早上 9 点创建一个 Workflow 实例，而英国的另一个用户 ( 伦敦，GMT+0)还在早上 9 点创建一个 Workflow 实例，这两个实例将相隔 5 个半小时，但列出例如通过同时创建的应用程序向第三个用户发送信息，这是不正确的。

所以，我会尝试使用其他东西来代替 LocalDateTime，也许 check this approach .

更新

检查Spring框架的源代码fully supported date types are these但对于 LocalDateTime 它使用 a read/write converter .
