最近做了一個demo例子，資料庫使用的是oracle 12c，用到的框架和技術如下POM：

在使用jpa做分頁查詢的時候報了一個錯誤
java.sql.SQLSyntaxErrorException: ORA-00933: SQL 命令未正確結束
檢視列印的sql：select X from X where X limit ?
oracle不支援limit的用法，需要在application.properties增加以下配置
#hibernate資料庫方言配置:
#org.hibernate.dialect.Oracle9iDialect,org.hibernate.dialect.Oracle10gDialect,org
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.Oracle12cDialect
增加配置後，輸出的sql為：select X from X where X fetch first ? rows only;
-----------------------------------------------------------------------
從springboot 1.X到springboot 2.X要注意的有
1.findOne(Long id) 改成 findById(Long id).get();
2.構造分頁時引數時 new PageRequest(0, 10, sort) 改成 findAll(specification, PageRequest.of(0, 1, sort));
