写项目想用mybatis-plus+swagger3，百度最新版代码生成器都是旧版的，且官网的配置过于简洁，所以手敲一份，在官网的基础上加了一堆配置，lombok，restful，mvc三层结构目录等等等等，记录备份

    <dependencies>
        <!--lombok-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>
        <!--代码生成器构建依赖-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
            <version>3.5.1</version>
        </dependency>
        <!--mybatis-plus-starter-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.4.3.4</version>
        </dependency>
        <!--默认模板，不引入这个会报错-->
        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
            <version>2.3</version>
        </dependency>
        <!--swagger3-->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-boot-starter</artifactId>
            <version>3.0.0</version>
        </dependency>
    </dependencies>

旧版可以直接通过new对象调用方法，全局配置，包配置等需要创建三个对象，新版只用一个构建类即可完成所有配置，注意需要先调用xxxBuild()方法在调用其他方法
