环境是Maven管理
1.POM文件下引入插件:org.mybatis.generator

2.resources下新增配置文件generator.xml,具体配置如下：

</table>
<!--<table tableName="proceeds_log">-->
<!--<generatedKey column="id" sqlStatement="Mysql" identity="true"/>-->
<!--</table>-->
</context>
</generatorConfiguration>
3.resources下新增配置文件jdbc-generator.properties,具体配置如下：
# 数据库配置
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/taotao?useUnicode=true&characterEncoding=utf-8&autoReconnect=true&allowMultiQueries=true&serverTimezone=GMT%2B8&useSSL=false
jdbc.user=root
jdbc.password=123456
# 通用Mapper配置
mapper.plugin=tk.mybatis.mapper.generator.MapperPlugin
mapper.Mapper=tk.mybatis.mapper.common.Mapper
