Java Spring存储库Rest资源-未保存子对象的问题
我一直在尝试使用SpringBoot实现RESTful接口，但遇到了一个问题 在发布以下JSON时，我得到一个org.hibernate.TransientObjectException异常（请参见下文），表明未保存子对象 在手动跟踪中，JSON似乎正确地呈现到域对象中，但当调用save（）方法（SimpleJPepository）时，它不会尝试通过任何子对象向下递归。这是故意的吗？如果是这样，配置@RepositoryRestResource以保存子对象的正确方法是什么 我有一个最小的spring.boot应用程序，如果它有助于诊断的话，我很乐意提供它 我一直在寻找一个有子对象（关系）的工作示例，但还没有找到。spring.io的例子对我来说非常有用，但我在扩展它时遇到了一些困难 代码片段如下所示：Java Spring存储库Rest资源-未保存子对象的问题,java,spring,spring-data,spring-data-jpa,spring-data-rest,Java,Spring,Spring Data,Spring Data Jpa,Spring Data Rest,我一直在尝试使用SpringBoot实现RESTful接口，但遇到了一个问题 在发布以下JSON时，我得到一个org.hibernate.TransientObjectException异常（请参见下文），表明未保存子对象 在手动跟踪中，JSON似乎正确地呈现到域对象中，但当调用save（）方法（SimpleJPepository）时，它不会尝试通过任何子对象向下递归。这是故意的吗？如果是这样，配置@RepositoryRestResource以保存子对象的正确方法是什么 我有一个最小的spri
