参考 https://github.com/zhou-hao/hsweb4-examples/blob/main/hsweb4-webflux-example/src/main/java/org/hswebframework/example/crud/web/TestController.java

Test 里的用法似乎是 4.0.16-SNAPSHOT 版本才有的，4.0.15可以直接升级吗？项目已在生产环境运行了

按理说可以，你可以先本地试一试。

okok，多谢大佬

[MoonBottle]

这边测试了下，暂时没发现什么问题，请问下 4.0.16 release 版本的发布计划是什么时间

[zhou-hao]

暂时还没有具体时间。

[MoonBottle]

明白了，多谢！

@zhou-hao 大佬，发现一个问题，使用
lamda 的方式，返回的实体类，有些字段不会被映射，手写sql没有这个问题

sql返回有值

怀疑是驼峰的问题，非驼峰的字段我看有值

[zhou-hao]

完整sql看一下， 原始sql和日志中执行的sql。

日志里捞出来的

select 
       j_0."ota_id"                   as "xxx.otaId",
       alarm_record."source_id"       as "all_1.sourceId",
       alarm_record."target_name"     as "all_1.targetName",
       alarm_record."handle_time"     as "all_1.handleTime",
       alarm_record."target_id"       as "all_1.targetId",
       alarm_record."level"           as "all_1.level",
       alarm_record."alarm_time"      as "all_1.alarmTime",
       alarm_record."description"     as "all_1.description",
       alarm_record."alarm_name"      as "all_1.alarmName",
       alarm_record."target_type"     as "all_1.targetType",
       alarm_record."target_key"      as "all_1.targetKey",
       alarm_record."alarm_config_id" as "all_1.alarmConfigId",
       alarm_record."source_type"     as "all_1.sourceType",
       alarm_record."id"              as "all_1.id",
       alarm_record."source_name"     as "all_1.sourceName",
       alarm_record."state"           as "all_1.state",
       alarm_record."business_type"   as "all_1.businessType"
from public.alarm_record alarm_record
         left join public.xxx j_0 on j_0."device_id" = alarm_record."target_id"
where alarm_record."state" = 'normal'
limit 10 offset 0;

手写sql方式查询用的sql

select * from alarm_record alarm_record " +
                    "left join xxx xxx on xxx.device_id = alarm_record.target_id

表名我因为保密原因，我替换成xxx了
