java - Spring Boot JOOQ 集成 - 编译问题

Question

我已经通过链接:java.lang.ClassNotFoundException: org.jooq.util.JavaGenerator和以下 https://www.javacodegeeks.com/2016/03/springboot-working-jooq.html .我正在使用 Java8 和 Spring Boot 2.2.2.RELEASE .

我使用 >mvn clean install -P mysql 构建项目，但它给了我以下错误。

Answer 1

SpringBoot 2.2.2 JOOQ starter 添加 jooq 3.12.3 和 JOOQ 代码生成移动到单独的库。添加以下依赖项:

<dependency>
    <groupId>org.jooq</groupId>
    <artifactId>jooq-codegen</artifactId>
    <version>3.12.3</version>
</dependency>

另外， org.jooq.util.DefaultGenerator 已弃用，您可以使用 org.jooq.codegen.JavaGenerator .
