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 工作流引擎并使用了 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，会发生 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，而不是使用 JPA 审计创建日期和修改日期
最佳答案
好吧，在那个巨大的堆栈跟踪中的某个地方是一段代码“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调试——我将从 GenericConversionService.getRequiredTypeInfo() 开始并向上搜索堆栈。
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 ，这可能受 Spring Data Auditing 支持，但由于 LocalDateTime 缺少唯一性信息(即时区)，因此可能有一些(Spring Framework)代码试图将 LocalDateTime 转换为 Joda Time 。
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 the logic I provided on a similar issue 的示例...
如果印度的用户( India Standard Time, GMT+5:30 )在早上 9 点创建了一个 Workflow 实例，而英国的另一个用户( London, GMT+0 )也创建了一个 Workflow例如，在早上 9 点，这两个实例相隔 5 个半小时，但列在例如由应用程序同时创建的第三个用户，这是不正确的。
所以，我会尝试使用其他东西而不是 LocalDateTime ，也许是 check this approach 。
更新
检查 Spring Framework 的源代码 fully supported date types are these 但对于 LocalDateTime 它使用 a read/write converter 。
关于jpa - LocalDateTime 和 JodaDate 冲突，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/53625838/
