Jpa分頁查詢遇到的bug

背景

1. 問題描述

使用Jpa hsql直接進行分頁查詢，查詢失敗

2. 報錯error

Caused by: java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: order near line 1, column 14 [select count(order) from xxx.xxx.DataFlow]

3. 問題位置

@Query(value = "from DataFlow order by timestamp")
Page<DataFlow> listByPage(Pageable pageable);

4. 解決方法

給表加別名

@Query(value = "from DataFlow t order by t.timestamp")
Page<DataFlow> listByPage(Pageable pageable);

5. 原因

暫時還沒有細看，簡單記錄，後續再補充
