jooq 3.12.0 自定義數據類型綁定生成代碼編譯錯誤

Question

我在 3.7.3 中使用了 jooq，現在我要升級到 jooq 3.12.0。 我在生成的代碼中看到編譯錯誤。

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碼中使用了我的自定義數據綁定類（“MySqlJsonBinding”），並且生成的代碼沒有出現編譯錯誤。

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>

生成的代碼：沒有編譯錯誤

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/為例。 我在生成的代碼中沒有看到“MySqlJsonBinding”，所以我不確定它是否被包含在內。

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>

生成的代碼：沒有編譯錯誤，但沒有 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，嘗試應用我用於 3.7.3 的方法。 我確實得到了生成的代碼，它確實包含 MySqlJsonBinding，但它有編譯錯誤。

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>

生成的代碼：

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

編譯錯誤如下：

任何想法我可能做錯了什么？ 謝謝。

jOOQ 3.12 引入了新的org.jooq.JSON類型，它會自動應用於您生成的代碼。 之前，該類型無法映射，因此生成為SQLDataType.OTHER ，對應於java.lang.Object

您的綁定之前有效，因為它可能是Binding<Object, YourType> 。 您必須將此綁定更改為Binding<JSON, YourType>以解決此問題。
