springboot2.0+jpa+oracle 分页 ORA-00933: SQL 命令未正确结束

最近做了一个demo例子，数据库使用的是oracle 12c，用到的框架和技术如下POM：

在使用jpa做分页查询的时候报了一个错误

java.sql.SQLSyntaxErrorException: ORA-00933: SQL 命令未正确结束

查看打印的sql：select X from X where X limit ? 

oracle不支持limit的用法，需要在application.properties增加以下配置

#hibernate数据库方言配置:

#org.hibernate.dialect.Oracle9iDialect,org.hibernate.dialect.Oracle10gDialect,org.hibernate.dialect.Oracle12cDialect；

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.Oracle12cDialect

增加配置后，输出的sql为：select X from X where X fetch first ? rows only;

-----------------------------------------------------------------------

从springboot 1.X到springboot 2.X要注意的有

1.findOne(Long id) 改成 findById(Long id).get();

2.构造分页时参数时 new PageRequest(0, 10, sort) 改成 findAll(specification, PageRequest.of(0, 1, sort));
