hibernate - 通过自定义复合用户类型的 JPADatabase 问题生成 JOOQ 代码

Question

我正在尝试使用 JPA Entity 的 JOOQ 代码生成。我已经创建了一个专用的 maven 模块，将在其中生成代码，该模块依赖于包含所有实体的模块以及带有 jooq 的代码生成插件。

为了更清楚地说明项目结构，这里是模块：（名称是组成的，但结构反映了我正在处理的当前项目）

net-example
  |- net-example-data (contains both entities and spring data repositories)
  |- net-example-jooq (where jooq plugin below is configured and should generate the code )
  |- net-example-business (business layer)
  |- net-example-api (api layer)

所以最后我想要的是，当我构建 net-example-jooq 时，它应该能够从 net-example-data 中找到的实体生成 jooq 类。

net-example-jooq 的 pom.xml

<build>
        .....
        <plugins>
            <plugin>
                <groupId>org.jooq</groupId>

...

这是包含自定义类型的实体之一。

@Entity
public class Example {

   @Id
   private UUID id;
   
   @Column(name = "NAME")
   private String name;


   @Columns(columns = {
            @Column(name = "CURRENCY"),
            @Column(name = "AMOUNT")
    })
    private Money moneyAmount; // org.javamoney.moneta.Money 

   ....

}

自定义类型使用 package.info 定义

@TypeDef(name = "money-type", typeClass = PersistentMoneyAmountAndCurrency.class, defaultForType = Money.class)
@TypeDef(name = "currency-unit-type", typeClass = PersistentCurrencyUnit.class, defaultForType = CurrencyUnit.class)
@TypeDef(name = "zone-id-type", typeClass = PersistentZoneIdAsString.class, defaultForType = ZoneId.class)
package net.example.data;

当我从根目录（包括数据模块、jooq 模块和其他）运行 mvn 编译项目时，我在构建 jooq 模块时收到以下错误。

对于一个简单的自定义类型，如果我使用 JPA 属性转换器，那么它可以正常工作。我知道没有直接支持通过 JPA 属性转换器将多个列与单个属性匹配（如果我没记错的话）

谁能在这里指导我如何使用 JPADatabase 处理 JOOQ 代码生成的复合类型？谢谢。

更新：

关于代码生成的问题是关于投影结构以及类路径中缺少类的位置。但是，关于复合类型的处理，请参阅接受的答案。

Answer 1

关于错误

我假设您缺少对代码生成类路径的依赖项。一旦你更新你的问题，我会更新我的答案。

关于 jOOQ 代码生成支持@TypeDef等。

jOOQ 不会在开箱即用的生成代码中支持您生成的复合类型，您仍然必须为此添加强制类型配置，可能是可嵌入的类型配置：

• https://www.jooq.org/doc/latest/manual/code-generation/codegen-advanced/codegen-config-database/codegen-database-forced-types/
• https://www.jooq.org/doc/latest/manual/code-generation/codegen-embeddable-types/

请注意，JPADatabase通过非常快速地与简单的 JPA 定义的模式集成，它提供了快速的胜利。它有它的警告。为获得最佳结果，我建议先使用 DDL（并从中生成 jOOQ 代码和 JPA 模型），因为将模式更改管理置于版本控制之下会容易得多，例如通过 Flyway 或 Liquibase。
