Java 嵌套异常无法执行语句：在Hibernate中获取HTTP状态500

我在Spring中一直在做这个项目，我试图添加一些功能，在本例中，这些功能会将int标记添加到我的MySQL数据库中，但在单击按钮后，我出现了以下错误：

HTTP状态500-请求处理失败；嵌套异常为org.springframework.orm.hibernate5.hibernatejdbceexception:JDBC-exception-on-Hibernate-data-access:SQLException-for-SQL[n/a]；SQL状态[HY000]；错误代码[1364]；无法执行语句；嵌套异常为org.hibernate.exception.genericjdbception:无法执行语句

这是控制台中的日志：

SEVERE: Servlet.service() for servlet [dispatcher] in context with path [/eschool] threw exception [Request processing failed; nested exception is org.springframework.orm.hibernate5.HibernateJdbcException: JDBC exception on Hibernate data access: SQLException for SQL [n/a]; SQL state [HY000]; error code [1364]; could not execute statement; nested exception is org.hibernate.exception.GenericJDBCException: could not execute statement] with root cause
