标签：代码生成 return else field gc blob import end MybatisPlus


一：新建springboot项目

二：导包

<dependencies>
  <dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-generator</artifactId>
    <version>3.3.2</version>
  </dependency>
  <dependency>
    <groupId>org.apache.velocity</groupId>
    <artifactId>velocity-engine-core</artifactId>
    <version>2.2</version>
  </dependency>
  <dependency>
    <groupId>org.freemarker</groupId>
    <artifactId>freemarker</artifactId>
    <version>2.3.30</version>
  </dependency>
  <dependency>
    <groupId>com.ibeetl</groupId>
    <artifactId>beetl</artifactId>
    <version>3.1.8.RELEASE</version>
  </dependency>
  <dependency>

    <artifactId>slf4j-simple</artifactId>
    <version>1.7.25</version>
    <scope>compile</scope>
  </dependency>
</dependencies>

三：复制相应的模板到\resources\templates目录下
