java.lang.AssertionError:org.hibernate.exception.sqlgrammareexception:无法插入：

我在我的项目中使用Spring Mvc Jpa mysql。 我的依赖项有一些问题需要解决，我有义务创建一个新项目，并将旧项目中的代码与其他依赖项一起复制。第一次我忘记了make create in：

             <property name="hibernate.hbm2ddl.auto" value="update"/>

我真的需要你的帮助

看来你还没有在

persistence.xml中指定实体类

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_0.xsd ">

希望这有帮助。

在OP中发布您的DTO。Hibernate无法正确写入您的表，您可能在映射上有一些问题。specialite class@JasonZI能够使用相同的代码插入iv刚刚将我的数据库更改为新数据库我发现了它我忘记添加spring core依赖项。谢谢你的帮助help@KaoutarLaz：您在哪里指定了实体类？不在persistence.xml中？我在applicationContext.xml中指定了这一点
