启动ApplicationContext时出错。若要显示条件报告，请在启用“调试”的情况下重新运行应用程序_applicationcontext报错_mango5208的博客

Error starting ApplicationContext. To display the conditions report re-run your application with ‘debug’ enabled

在启动springboot项目，突然报以下错误：

因为我自己用的是mabatisplus的自动生成代码一键生成的。总体结构如下：
 
 错误说的我 ‘customerServiceImpl’ 出错了，我去检查，并未出现任何错误，与我之前的几乎一样（之前并没有出错），因为刚生成，未写任何代码。
 
 多次检查发现，说我并没有满足
 unsatisfied dependency expressed through field ‘baseMapper’;
 字段“baseMapper”表示的不满足的依赖关系； 
随后检查启动类的mapper.发现了问题，我们常常喜欢将所有的层级都放在一个包下，所有启动类扫描包时，由于我个人将系统模块和业务模块分不同的包，所以没有扫描到。 
将sys改成 * 这样就能扫描到主路径下的所有mapper了

				在前面两篇文章中，我们已经对ApplicationContext的大部分内容做了介绍，包括国际化，Spring中的运行环境，Spring中的资源，Spring中的事件监听机制，还剩唯一一个BeanFactory相关的内容没有介绍，这篇文章我们就来介绍BeanFactory，这篇文章结束，关于ApplicationContext相关的内容我们也总算可以告一段落了。本文对应官网中的1.16及1.15小结
前面我们也提到了ApplicationContext继承了BeanFactory接口，其继承关系如下：
下面我们直接进入BeanFactory相关内容的学习
