Oracle字段名区分大小写的坑

遇到问题描述：

1.程序环境：spring boot data jpa
2.用powerdesigner16 从SqlServer导出了一份oracle的建表语句；在oracle中执行了该语句后，修改程序的实体类后（主要修改主键生成策略），使用jpa save(entity)时出现错误ORA-00904: “CONTENT”: 标识符无效；核对了字段名称，发现content这个字段名称并没有错误，又仔细观察了下，发现oracle库中的字段是小写的，实体类中映射的字段是大写的；恍然大悟。。。

以下是详细错误信息：

被powerdesigner导出的建表语句所坑

可以发现，字段名都有双引号引起来，经测试，oracle中建表时如果字段不加双引号，那么字段默认都是大写，加了双引号，以双引号里的为准。
