使用 jooq-codegen-maven mysql-connector-javamysql maven自动生成数据库代码总结
之前使用的是jooq3.8生成数据库代码，之后很久没有使用这个功能，再次用的时候想改为jooq最新版3.11.4，发现不能生成代码了。
so 一番折腾后，重新整理了这个内容。
对于jooq的配置网上很多了，这里转一个我参考的：https://hellokoding.com/jooq-example-with-mysql/
感谢Giau Ngo的总结：
This post walks you through the process of creating a jOOQ example with MySQL.
What you'll need
- JDK 1.7+
- Maven 3+
- MySQL 5.6+
Stack
- Java
- jOOQ

Create database
Run below script to create a sample MySQL database
create_db.sql
CREATE DATABASE `library`;
USE `library`;
CREATE TABLE `author` (
`id` int NOT NULL,
`first_name` varchar(255) DEFAULT NULL,
`last_name` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
);
INSERT INTO author(1, 'Hello', 'Koding');
INSERT INTO author(2, 'jOOQ', 'Example');
Run

package com.hellokoding.jooq;

System.out.println("ID: " + id + " first name: " + firstName + " last name: " + lastName);

上面的配置是完美的，只是当JOOQ升级到3.11以后，编译时会出现以下error:
[WARNING] Type not found : Your configured org.jooq.util type was not found.
Do note that in jOOQ 3.11, jOOQ-meta and jOOQ-codegen packages have been renamed. New package names are:
- org.jooq.meta
- org.jooq.meta.extensions
- org.jooq.codegen
- org.jooq.codegen.maven
See https://github.com/jOOQ/jOOQ/issues/7419 for details

解决办法就是根据说明修改pom.xml中的 org.jooq.util 为 org.jooq.meta
org.jooq.meta.mysql.MySQLDatabase

好了，现在mvn clean compile就可以生成数据库的代码了。
