mybatis-plus代码生成器

一、新建maven项目

二、配置pom.xml

<properties>
    <mysql.version>8.0.17</mysql.version>
</properties>

<dependencies>
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-generator</artifactId>
        <version>3.2.0</version>
    </dependency>
    <dependency>
        <groupId>org.apache.velocity</groupId>
        <artifactId>velocity-engine-core</artifactId>
        <version>2.1</version>
    </dependency>
    <dependency>
        <groupId>org.freemarker</groupId>
        <artifactId>freemarker</artifactId>
        <version>2.3.29</version>
    </dependency>
    <dependency>
        <groupId>com.ibeetl</groupId>
        <artifactId>beetl</artifactId>
        <version>3.0.11.RELEASE</version>
    </dependency>
    <!--mysql数据库驱动-->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>${mysql.version}</version>
    </dependency>
</dependencies>

 

三、使用方法
