jooq 3.12.0 自定义数据类型绑定生成代码编译错误

Question

我在 3.7.3 中使用了 jooq，现在我要升级到 jooq 3.12.0。我在生成的代码中看到编译错误。

使用 jooq 3.7.3 版，使用https://www.jooq.org/doc/3.7/manual/code-generation/custom-data-type-bindings/。我可以看到在生成的代码中使用了我的自定义数据绑定类（“MySqlJsonBinding”），并且生成的代码没有出现编译错误。

我的 jooq.xml 的一部分：

<customTypes>
    <customType>
    <name>JsonElement</name>
    <type>com.google.gson.JsonElement</type>
    <binding>jooq.MySqlJsonBinding</binding>
    </customType>
</customTypes>
<forcedTypes>
    <forcedType>
        <name>JsonElement</name>
        <expression>board_data</expression>
        <types>JSON</types>
    </forcedType>
</forcedTypes>

生成的代码：没有编译错误

public final TableField<UserBoardRecord, JsonElement> BOARD_DATA = createField("board_data", org.jooq.impl.DefaultDataType.getDefaultDataType("json"), this, "", new MySqlJsonBinding());

使用 jooq 3.12.0 版，以https://www.jooq.org/doc/latest/manual/code-generation/custom-data-type-bindings/为例。我在生成的代码中没有看到“MySqlJsonBinding”，所以我不确定它是否被包含在内。

我的 jooq.xml 的一部分：

<forcedTypes>
    <forcedType>
        <userType>com.google.gson.JsonElement</userType>
        <binding>com.samplecompany.jooq.MySqlJsonBinding</binding>
        <includeExpression>.*JSON.*</includeExpression>
        <includeTypes>.*</includeTypes>
    </forcedType>
</forcedTypes>

生成的代码：没有编译错误，但没有 MySqlJsonBinding：

public final TableField<UserBoardRecord, JSON> BOARD_DATA = createField(DSL.name("board_data"), org.jooq.impl.SQLDataType.JSON, this, "");

最后，我使用 3.12.0，尝试应用我用于 3.7.3 的方法。我确实得到了生成的代码，它确实包含 MySqlJsonBinding，但它有编译错误。

我的 jooq.xml 的一部分：

<forcedTypes>
    <forcedType>
        <userType>com.google.gson.JsonElement</userType>
        <binding>com.samplecompany.jooq.MySqlJsonBinding</binding>
        <includeExpression>board_data</includeExpression>
        <includeTypes>JSON</includeTypes>
    </forcedType>
</forcedTypes>

生成的代码：

public final TableField<UserBoardRecord, JsonElement> BOARD_DATA = createField(DSL.name("board_data"), org.jooq.impl.SQLDataType.JSON, this, "", new MySqlJsonBinding());

编译错误如下：

任何想法我可能做错了什么？谢谢。

jOOQ 3.12 引入了新org.jooq.JSON类型，它会自动应用于您生成的代码。之前，类型无法映射，因此生成为SQLDataType.OTHER，对应于java.lang.Object

您的绑定以前可以使用，因为它可能是Binding<Object, YourType>. 您必须将此绑定更改为Binding<JSON, YourType>以解决此问题。
