今天使用AutoGenerator生成代碼，出現NoClassDefFoundError: freemarker/template/Configuration

詳細報錯為

解決的方法

引入兼容版本的freemaker依賴

<dependency>
    <groupId>org.freemarker</groupId>
    <artifactId>freemarker</artifactId>
    <version>2.3.28</version>
        <scope>compile</scope>
</dependency>

說明：

AutoGenerator 是 MyBatis-Plus 的代碼生成器，通過 AutoGenerator 可以快速生成 Entity、Mapper、Mapper XML、Service、Controller 等各個模塊的代碼，極大的提升了開發效率
