KotlinGenerator
适用于 ✅ 开源版 ✅ 专业版 ✅ 企业版
jOOQ 可以生成 Kotlin 代码而不是 Java 代码，这允许在生成的代码中利用一些 Kotlin 语言特性。
为了使用 KotlinGenerator，只需将以下类引用放入您的代码生成配置中
XML（独立和 Maven）
编程方式
Gradle (Kotlin)
Gradle (Groovy)
Gradle（第三方）
<configuration>
<generator>
<name>org.jooq.codegen.KotlinGenerator</name>
</generator>
</configuration>
有关更多详细信息，请参阅 configuration XSD、独立代码生成 和 Maven 代码生成。
new org.jooq.meta.jaxb.Configuration()
.withGenerator(new Generator()
.withName("org.jooq.codegen.KotlinGenerator")
)
有关更多详细信息，请参阅 configuration XSD 和 程序化代码生成。
import org.jooq.meta.jaxb.*
configuration {
generator {
name = "org.jooq.codegen.KotlinGenerator"
}
}
有关更多详细信息，请参阅 configuration XSD 和 Gradle 代码生成。
configuration {
generator {
name = "org.jooq.codegen.KotlinGenerator"
}
}

// The jOOQ-codegen-gradle plugin has been introduced in version 3.19. // Please use the official plugin instead of the third party plugin that was recommended before.
只要与生成语言无关，大多数代码生成配置都保持不变。但是有一些 Kotlin 特定的配置标志，如下所示
XML（独立和 Maven）
编程方式
Gradle (Kotlin)
Gradle (Groovy)
Gradle（第三方）

<generate>

虽然很想在生成的代码中使用从表定义派生的非空保证，但重要的是要记住，在 SQL 中，有很多原因导致基于声明为 SQLNOT NULL的列的表达式可以通过使用 SQL 运算符（例如LEFT JOIN或UNION等）变为NULL。特别是，具有DEFAULT或IDENTITY表达式的列是“写入时可为空”的，因此 jOOQ 会将其生成为可为空，即使有NOT NULL约束！
