代码生成器：MyBatis-Plus代码生成自定义模版

简述

AutoGenerator 是 MyBatis-Plus 的代码生成器，通过 AutoGenerator 可以快速生成 Entity、Mapper、Mapper XML、Service、Controller 等各个模块的代码，极大的提升了开发效率。

添加依赖

MyBatis-Plus 从 3.0.3 之后移除了代码生成器与模板引擎的默认依赖，需要手动添加相关依赖：

	<!-- mybatis代码生成器 -->
	<dependency>
	    <groupId>com.baomidou</groupId>
	    <artifactId>mybatis-plus-generator</artifactId>
	    <version>3.4.0</version>
	</dependency>
	<!-- mybatis核心代码 -->
	<dependency>
	    <groupId>com.baomidou</groupId>
	    <artifactId>mybatis-plus-core</artifactId>
	    <version>3.4.0</version>
	</dependency>
	<!-- 数据库连接 -->
	<dependency>
	    <groupId>mysql</groupId>
	    <artifactId>mysql-connector-java</artifactId>
	    <version>5.1.38</version>
	</dependency>
	<!-- 自定义模版引擎 -->
	<dependency>
	    <groupId>org.freemarker</groupId>
	    <artifactId>freemarker</artifactId>
	    <version>2.3.30</version>
	</dependency>
	<!-- java模版引擎 -->
    <dependency>
        <groupId>org.apache.velocity</groupId>
        <artifactId>velocity</artifactId>
        <version>1.7</version>
    </dependency>

复制maven包内的模版

maven仓库内搜索mybatis-plus-generator，打开，复制其中的templates目录至resources

由于我们后续使用的是FreemarkerTemplateEngine，仅用到.ftl文件，其他后缀文件可自行删除。
