jOOQ，是一个ORM框架，利用其生成的Java代码和流畅的API，可以快速构建有类型约束的安全的SQL语句

2. 配置类
/**
* 按照{@link JooqAutoConfiguration}仿写
*/
@Configuration
@EnableTransactionManagement
@Slf4j
public class JooqConfiguration {
/**
* 创建DSL的上下文，
* DSLContext可以去拼接sql信息。
*/

//配置信息

}
}
3. 配置文件
mysql:
master:
datasource:
name: master_test
url: jdbc:mysql://localhost:3306/test
username: root
password: root
driver-class-name: com.mysql.jdbc.Driver
salve:
datasource:
name: salve_test
url: jdbc:mysql://localhost:3306/jooq
username: root
password: root
driver-class-name: com.mysql.jdbc.Driver
4. 使用mvn命令自动生成代码
注意事项：生成代码时，要确保项目是可以编译成功的，否则代码会生成失败，而异常信息却也看不出来到底哪里失败。
生成后的目录格式：
