我写了一个教育项目。这是一个简单的聊天。后端技术栈是Java、Jetty（服务器、Web Socket）、Hibernate 5.3.7。最后，PostgreSQL。
我遇到了运行时异常org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: missing column [conversation_c_id] in table [conversation_reply]。这个错误让我玩了几天。我将不胜感激解决这个问题的帮助。
这是实体部分的基本结构：

@OneToMany(mappedBy = "conversation", cascade = CascadeType.ALL, orphanRemoval = true)
private List<ConversationReplyDataSet> conversationReplies = new ArrayList<>();
@Entity
@Table(name = "conversation_reply") //public class ConversationReplyDataSet
@Id
@SequenceGenerator(name = "crIdSequence", sequenceName = "cr_id_sequence", allocationSize = …
