springBoot+mybatis入门微信小程序
信誓旦旦学习一些新玩意，结果一上来就踩坑，
#视频讲解用的SpringBoot 版本是1.5.9 而我用的版本是2.2.2 由于springboot 2.0之前的版本一直用的是 server.context.path="/",之后则是 server.servlet.context-path="/"，这是我看见的区别（ 别丢了斜杠“/”噢）
XML的基本配置：
mybatis-config.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!--XML基本配置 -->
</configuration>
坑2：
错误信息：
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

Description:
Field areaService in com.small.wechat_small_project.controller.AreaController required a bean of type 'com.small.wechat_small_project.service.AreaService' that could not be found.
The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'com.small.wechat_small_project.service.AreaService' in your configuration.
解决办法尤为简单，只是在写实现类的时候忘记家业务的注解了“@Service” 扎心了 老铁！
