MyBatis Plus中代码生成器使用

按照官网上实例尝试了一下，感觉MyBatis plus中代码生成器还是很强大的，以下是测试的总结：

使用MybatisPlus的主要依赖

• 引入plus依赖（苞米豆）

<dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.1.1</version></dependency>

• 生成器依赖

<dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-generator</artifactId><version>3.1.1</version></dependency>

• 模板依赖

<dependency><groupId>org.freemarker</groupId><artifactId>freemarker</artifactId><version>2.3.28</version></dependency>

测试的pom依赖（也有我测试别东西的依赖，多余的请忽略）

}

注意：测试时输入的表名必须和数据库中一致，区分大小写。

疑问：生成的实体类当中没有id。求解
