【中文标题】Jooq 强制类型未应用于列【英文标题】:Jooq forced type not being applied to column 【发布时间】:2021-11-15 04:45:36 【问题描述】:

我正在尝试将 jOOQ 与具有 tsvectors 的 postgres 数据库一起使用。我将此添加到我的配置文件中:

<forcedTypes>
    <forcedType>
        <userType>example.textsearch.TsVector</userType>
        <includeTypes>.*tsvector.*</includeTypes>
    </forcedType>
</forcedTypes>

我正在尝试将其应用于ts_message_text 列:

[DEBUG] Fetched result           : +---------------+----------------+-----------------+------------------------+-----------------+-------------+-----------+-----------+--------------+----------+--------+-----------+

但我明白了:

[WARNING] Unused forced types      : There are unused forced types, which have not been used by this generation run.
This can be because of misconfigurations, such as, for example:
- case sensitive regular expressions
- regular expressions depending on whitespace (Pattern.COMMENTS is turned on!)
- missing or inadequate object qualification
- the object to which the configuration was applied in the past has been dropped
Try turning on DEBUG logging (-X in Maven, and <logging/> in jOOQ) to get additional info about the schema
[WARNING] Unused forced type       : <priority>0</priority><userType>example.textsearch.TsVector</userType><includeTypes>.*tsvector.*</includeTypes><nullability>ALL</nullability><objectType>ALL</objectType>

【问题讨论】:

【参考方案1】:

上面应该有一条额外的日志消息:

[WARNING] Bad configuration for <forcedType/>. Either <binding/> or <converter/> 
  or <enumConverter/> or <lambdaConverter/> is required

在您的特定情况下,这条消息似乎没有在 jOOQ 3.15.3 中打印出来,不过……似乎是一个日志记录错误。
