jpa - LocalDateTime 和 JodaDate 冲突
问题描述
我正在使用 spring MVC、hibernate、Spring Data JPA 项目创建一个多模块 Maven 项目。目前我已经集成了一个 Activiti 工作流引擎并使用 Joda 日期依赖。但是我的模型类使用 java 8 LocalDateTime。Spring Data JPA 审计（@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 -
我的问题是当我保存工作流对象时出现Joda LocalDate not present 错误
java.lang.TypeNotPresentException: Type org.joda.time.LocalDate not present

并且没有其他日期字段，而不是 JPA 审计的创建日期和修改日期
解决方案
好吧，在那个巨大的堆栈跟踪中，有一段代码正在org.joda.time.LocalDate“按名称”查找类，而 JVM 找不到它。
找到问题的唯一方法是调试——我会从堆栈开始GenericConversionService.getRequiredTypeInfo()并搜索堆栈。
但是，关于你列出的模型类......
@CreatedDate和都使用Spring Data Auditing可能支持@LastModifiedDate的（我假设是 Java 8），但由于缺少唯一性信息（即时区），可能有一些（Spring Framework）代码试图转换为 JodaTime。LocalDateTimeLocalDateTimeLocalDateTime
人们应该使用一个在世界范围内独一无二的值进行审计。
使用您的模型和我在类似问题上提供的逻辑的示例......如果印度的用户（印度标准时间，GMT+5:30Workflow ）在早上 9 点创建一个实例，而另一个用户在英国（伦敦，GMT+0）也在早上 9 点创建一个Workflow实例，这两个实例将相隔 5 个半小时，但例如由应用程序同时创建的第三个用户列出不对。
所以，我会尝试使用其他东西而不是LocalDateTime，也许检查这种方法。
更新
检查 Spring Framework 的源代码，完全支持的日期类型是这些，但LocalDateTime它使用读/写转换器。
