異常原因：service在呼叫dao層，dao層在找對映mapepr檔案時報錯，就是因為沒有找到mapper對映檔案。
在Maven專案中目錄分為：
----java
----resources
----webapp
java中編寫：java程式碼
resources中編寫：各種配置檔案
webapp中編寫：表示層
解決方法：只需把mapper對映檔案放置在resources目錄下，spring配置檔案中mapperLocations的值，直接寫resources下的路徑就好，如下圖：
<property name="mapperLocations" value="classpath:MybatisMapper/*.xml"/>
其他： classpath:/xxx 和 classpath:xxx是一樣的
classpath:xxx 和 classpath*:xxx是不一樣的，前者表示引入一個，後者表示引入多個。
博主標語：如果有錯誤或者不足歡迎指正，本人也是在學習！
