1.导入依赖
-
导入 mybatis-plus-generator 依赖
<dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-generator</artifactId> <version>3.5.3.1</version> </dependency> -
导入模板引擎
MyBatis-Plus 支持 Velocity（默认）、Freemarker、Beetl，用户可以选择自己熟悉的模板引擎，如果都不满足您的要求，可以采用自定义模板引擎。这里我们使用 freemarker 模板引擎。
<!-- 模板引擎 --> <dependency> <groupId>org.freemarker</groupId> <artifactId>freemarker</artifactId> <version>2.3.31</version> </dependency>
