在此项目中执行mvn deploy并在另一个从该项目导入包的项目中mvn -U clean install后，在保存实体时出现以下错误：

org.springframework.orm.jpa.JpaSystemException: Error accessing field [private java.lang.String is.godo.server.property.server.entity.Invoice.description] by reflection for persistent property [is.godo.server.property.server.entity.Invoice#description] : is.godo.server.property.server.entity.Invoice@384fb0b8; nested exception is org.hibernate.property.access.spi.PropertyAccessException: Error accessing field [private java.lang.String is.godo.server.property.server.entity.Invoice.description] by reflection for persistent property [is.godo.server.property.server.entity.Invoice#description] : is.godo.server.property.server.entity.Invoice@384fb0b8

之前已经发生这种情况，以前的员工花了很多时间才发现它与两次加载的类或者非常奇怪的东西有关。我所知道的是，它不需要修改代码就可以在上次修复它。

我已经尝试从.m2中移除这些类并进行目标和重建，但没有运气。

如果那是相关的，我也在使用Intellij。

有什么想法吗？

EDI：

我已经解决了这个问题，但我无法解释它为何有效。使用java -jar运行uberjar工作，之后它再次在Intellij中工作。

答案 0 :(得分：2)

这是你的实际例外：

Caused by: java.lang.IllegalArgumentException:
   Can not set java.lang.String field 
        is.godo.server.property.server.entity.Invoice.description
     to is.godo.server.property.server.entity.Invoice

您最近是否进行了架构更改？ Hibernate认为这个字段是一个字符串，但你试图输入一个实际的发票。你忘了运行元数据生成器了吗？您是否在会话中存储hibernate对象？如果是这样，请尝试更改序列化版本。
