在resource目录创建mysql.properties配置文件
driver=com.mysql.cj.jdbc.Driver url=jdbc:mysql://localhost:3306/db_test?useSSL=false&serverTimezone=UTC&characterEncoding=utf8&useUnicode=true user=root password=root
代码生成需要依赖 freemarker 否则报异常:java.lang.NoClassDefFoundError: freemarker/template/Configuration
springboot:使用以下方式添加依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-freemarker</artifactId> <version>2.1.8.RELEASE</version> </dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-generator</artifactId>
<version>3.4.1</version>
</dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus</artifactId>
<version>3.0.6</version>
</dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.0.6</version>
</dependency>
最后执行main()方法
