2023-12-25后端工程搭建

1.环境确认

2.工程框架搭建
spzx-parent： 尚品甄选项目的父工程，进行项目依赖的统一管理，打包方式为pom
spzx-common: 尚品甄选项目公共模块的管理模块，父工程为spzx-parent
common-util: 工具类模块，父工程为spzx-common
common-service：公共服务模块，父工程为spzx-common
spzx-model: 尚品甄选实体类模块
spzx-manager： 尚品甄选项目后台管理系统的后端服务

3.设置maven和字符集

补充知识

• 一个项目中所涉及到的实体类往往有三种：

1、封装请求参数的实体类：这种实体类在定义的时候往往会携带到dto【数据传输对象：Data Transfer Object】字样，会定义在dto包中

2、与数据库对应的实体类：这种实体类往往和数据表名称保证一致，会定义在domain、entity、pojo包中

3、封装响应结果的实体类：这种实体类在定义的时候往往会携带到vo【视图对象：View Object】字样，会定义在vo包中
