org.hibernate.MappingException:无法确定类型，找到配置文件，更改属性

id类型type为Integer导致,改为hibernate映射类型integer或者改为java类型java.lang.Integer就可以了；

type类型只能写java类型或者hibernate映射类型,在储存数据时候hibernate会根据设定的类型转换成相应的数据库类型，
部分hibernate映射类型 对应java类型

integer      java.lang. Integer
string       java.lang.String
character    java.lang.String
double       java.lang. Float
long         java.lang.Long
short        java.lang.Short
float        java.lang. Float
time         java.util. Date ; java.sql. Time
date         java.util. Date ; java.sql. Date

LightDB/PostgreSQL的类型系统

在LightDB中，支持了丰富的数据类型，函数，操作符，这些功能对类型系统有很大影响，而LightDB中的操作符等价于函数，并且以重载的方式来实现，在一些场景下，重载函数的选择结果可能会造成用户的困惑。所以有必要深入了解类型系统的实现策略。

在做项目的时候遇到这个问题，原因是原本的数据类型是Date类型，由于Date类型插入数据库比较麻烦，改成了String类型，使用ctrl+f 查找替换导致的。最后网上有网友也有一样的问题，正好我看到了对于String 是java.lang.String而对于Date 是java.util.Date否者报错Could not determine type for: java.util.String,

而@TableField注解来自于MyBatis-Plus框架，用于标识一个Java类的属性与数据库表中的字段的映射关系。因为@Transient和@Entity同样来自于JPA规范，@Transient也是用来标识一个Java类的属性不需要进行持久化。原因是@Entity注解和@TableField(exist = false)是两个不同的注解，来自于不同的框架。看了网上的很多解决方法比如注解要么写在字段上，要么写在getXX上，不能混合使用，否则会报这个错误，试过不行。
