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）

mpg.execute(); } }

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
