jOOQ，是一個ORM框架，利用其生成的Java代碼和流暢的API，可以快速構建有類型約束的安全的SQL語句

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命令自動生成代碼
注意事項：生成代碼時，要確保項目是可以編譯成功的，否則代碼會生成失敗，而異常信息卻也看不出來到底哪裏失敗。
生成後的目錄格式：
