认真是一种态度,坚持是一种品格,优秀是一种习惯！
掰着手指头算算，从15年毕业到现在，已经是工作的第四个年头了。都说程序猿3年是个坎，我也不知道算是个坎还是不是坎。反正工作还在继续，学习不能停止。越工作越觉得自己啥也不会<><ganga .....扯远了，说回正题。
自打用了Mybatis-Plus觉得开发快了不止一星半点。但是每次新增一个业务时总要从bean到mapper再到service搞一遍总还是有些不爽的，还在mp有diamante生成器，简单记录一下这个代码生成器怎么玩。
1 基础框架
SpringBoot 2.0.6、JDK 1.8、mybatis-plus 3.1.1、mybatis-plus-generator 3.1.1、velocity 1.7、MySQL 5.7
因基本都称mybatis-plus为mp,后面我都简称mp
2.具体实现
- 创建项目我就不在描述了，学习第一天记录过了坚持学习第一天
- 因为mp 3.1.1版本把代码生成单独拎出来了，所以需要在原项目基础上加上generate相关包。
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-generator</artifactId>
<version>3.1.1</version>
</dependency>
<dependency>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity</artifactId>
<version>1.7</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.34</version>
</dependency>
因为代码生成的模板我这里选择用velocity，所以将velocity 包引入了。语法参考：https://jzhua.iteye.com/blog/311405
默认可以直接使用mp提供的默认模板文件。
这里先简单通过执行main方法的形式使用该代码生成器，mp的代码生成器很完善，基本上满足开发的基本需要。
基础表
create database demo_generate;
use demo_generate;
create table if not exists t_equipment (
equipment_id int(11) not null AUTO_INCREMENT comment '设备ID',
device_name varchar(50) comment '设备名称',
modnum varchar(50) comment '设备编号',
picture varchar(255) comment '设备图片',
create_time date comment '创建时间',
enabled tinyint(4) default 0 comment '1启用/0禁用',
primary key (equipment_id)
)ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='设备信息';
先简单看一下执行效果：

通过执行日志，我们基本上能看到整个生成执行过程，先读取数据相关信息，将读取到信息通过流输出到模板，模板解析生成对应得bean,mapper等文件。
