src.main.java.com.taotao.pojo VS com.taotao.pojo

本文主要是介绍src.main.java.com.taotao.pojo VS com.taotao.pojo，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

src.main.java.com.taotao.pojo VS com.taotao.pojo

一,前言:

有些问题看似很简单, 但是有时一下没有想到或没能解决或有的同学没遇到过,就会变得非常的尴尬,但也不要着急,最好的办法就是: 站在巨人的肩膀上.

二,问题

这次在引入实体时,硬是引入不对,总是报错.

命名实体位置是在: com.taotao.pojo 中, 但是引入包是却出现src.main.java.com.taotao.pojo

三,详情

1,分析情况,这是因为引入包的方式不对,一, pom中可能没有引入自己; 二, pom可能实体的依赖不对.

2,解决方案:

在 pom 中, 必须引入自己的同时,也要有对其他包的依赖.

3,原理:

Mapper 依赖 pojo

Service 要依赖 mapper

Web 要依赖 Service
