Java Hibernate框架在数据库中保存记录
我开始使用Hibernate框架。我试图在数据库中保存一些记录。在保存时，我遇到了这个错误。在解决这个问题时需要专家评审 错误：所需的Expanditure参数“Expanditure”不存在 我不知道怎么解决这个问题。若我从控制器类中删除这些参数，则字段变为空，若将这些expanditure参数放入，则返回错误 这里是实体类Java Hibernate框架在数据库中保存记录,java,spring,hibernate,Java,Spring,Hibernate,我开始使用Hibernate框架。我试图在数据库中保存一些记录。在保存时，我遇到了这个错误。在解决这个问题时需要专家评审 错误：所需的Expanditure参数“Expanditure”不存在 我不知道怎么解决这个问题。若我从控制器类中删除这些参数，则字段变为空，若将这些expanditure参数放入，则返回错误 这里是实体类 package com.bvas.insight.entity; /** * * @author shoaib */ import java.io.Serial
