Question

我有一个jdbc入站通道适配器，其定义如下所示。我正在使用MySQL数据源。我想更新已轮询的行的状态。我正在尝试遵循此文档：spring integration ref. mannual。我的理解是：id应该映射到SELECT查询返回的所有id的集合。

<int-jdbc:inbound-channel-adapter
    channel="targetChannel" data-source="dataSource"
    query="SELECT * FROM mytable WHERE status=''" row-mapper="myRowMapper"
    max-rows-per-poll="500"
    update="UPDATE mytable SET status='IN_PROGRESS' WHERE id in (:id)">
    <int:poller fixed-delay="60000" />
</int-jdbc:inbound-channel-adapter>

SELECT查询执行正常，我确保RowMapper按预期映射所有生成的行，但是当它尝试使用给定的UPDATE查询进行更新时，我得到以下异常：

我在这里做错了什么？

Answer 1

发现我的错误，感谢Artem Bilan。我认为：id会映射到＆＃34; id＆＃34; SELECT结果集中的列名称之间，而不是POJO上的getId（）。我的RowMapper正在映射＆＃34; id＆＃34;进入＆＃34; requestId＆＃34;在POJO中。那是错误的。
