显然日志这种复制出来的日志不好看
错误之处
我之所以说这个Bug让我一脸懵逼，是因为它的提示：
dishBasicController
dishServiceImpl
dishMapper
sqlSessionFactory
- 我的结构就是传统的DAO-Service-Controller,所以一层一层剥下来，是说dishMapper这个mapper出错了~，出错原因是工厂创建抛出了个异常~
- 也正因此，这四个关键词一度让我以为是配置出了问题（应为这个controller是很早之前就测试过的），于是疯狂检查配置（本来就是对的，根本不能检查出个啥玩意）,在这里作为大水比的我就不得不吐槽一下报错功能了，直接误导我往错误的方向找，虽然也有一部分懒得看日志的因素在里面
我曾经试图度娘，造成这种错误的原因五花八门，无果
无奈之下，只能硬着头皮继续读报错日志，于是就找到了第五个关键字DishCustomMapper.xml，
和一段话：
Could not resolve type alias 'DishCustomAndSource'. Cause: java.lang.ClassNotFoundException: Cannot find class:
各位可能还不知道这个词和这句话代表着什么，我在这里解释一下：
DishCustomMapper.xml，是我刚建立的一个xml文件
这句话的意思是DishCustomAndSource找不到这个类型,罪魁祸首在此... ...
<resultMap type="DishCustomAndSource" id="com.ch.home.bean.DishCustom">
<id column="custom_id" property="customId"></id>
<result column="dish_id" property="dishId"></result>
<result column="custom_content" property="customContent"></result>
