Caused by: org.hibernate.tool.schema.spi.SchemaManagementException: Unable to execute schema manag

这里通过  spring jpa 设计数据的时候，处理问题，问题如下

Caused by: org.hibernate.tool.schema.spi.SchemaManagementException:
Unable to execute schema management to JDBC target

[create table order (id integer not null, order_time datetime, shop_id integer not null auto_increment, customer_id integer not null, car_id integer not null, primary key (shop_id, id, customer_id, car_id))]

看一下，可能数据哭的版本问题，或者是建立表的结构有问题，但是，一般人，都会先怀疑，是自己的pojo 映射表出现问题，

后来，测试，最简单的ｐｏｊｏ还是有问题，于是，就怀疑是数据库的版本有问题，于是，我换了一个pojo的类名称，ｏｋ，搞定

之前，使用的是Order   ,后来，改为　Item ,可能是数据库，把这个作为，一个系统的文件，不让改．所以．．．．
