将 Spring Boot 版本从 1.3.5 升级到 1.4.2 后 DB2ZOS 方言不起作用

Question

在将 Spring Boot 版本从 1.3.5 升级到 1.4.2 之后，DB2ZOS 方言似乎不适用于 Spring JPA 中的分页查询，之前它正在工作。 我将 Spring JPA 与 DB2 一起使用，当我使用分页存储库并查询第二页时，它会引发错误。这是生成的查询。

select
        * 
    from
        ( select
            inner2_.*,
            rownumber() over(
        order by

        order of inner2_) as rownumber_ from
            ( select
                componentd0_.comp_data_field_st_msg_id as comp_dat1_0_,
                componentd0_.comp_data_file_id as comp_dat5_0_,
                componentd0_.comp_data_file_field_id as comp_dat6_0_,
                componentd0_.component_serial_no as componen2_0_,
                componentd0_.controller_short_name as controll3_0_,
                componentd0_.message as message4_0_ 
            from
                cs_comp_data_field_st_msg componentd0_ 
            left outer join
                cs_comp_data_file componentd1_ 
                    on componentd0_.comp_data_file_id=componentd1_.comp_data_file_id 
            where
                componentd1_.comp_data_file_id=? 
            order by
                componentd0_.comp_data_field_st_msg_id asc fetch first 50 rows only ) as inner2_ ) as inner1_ 
        where
            rownumber_ > 25 
        order by
            rownumber_

Answer 1

org.hibernate.dialect.DB2Dialect 类生成无效查询，说明它失败的原因。我已经覆盖了我方言中的 getLimit 函数并解决了它。
