Answer 1

我想你的對象映射/ HQL語句不正確，因此導致無效的SQL。嘗試通過配置啓用SQL（show_sql = true），並查看生成的SQL中的錯誤。這會讓你更好地理解這個問題。

Answer 2

這裏是你的問題：

Caused by: com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'long, lat, is_found, missing_name, missing_age, is_person) values ('immfarag@gam' at line 1 

，Hibernate對產生了對你的SQL語法不正確。

這是使用Hibernate的危害之一：如果您不喜歡或理解它爲您生成的SQL，可能會發現自己陷入一片混亂。

這不是完整的SQL語句。我建議讓它看看問題是什麼。
