... 50 more异常原因：service在调用dao层，dao层在找映射mapepr文件时报错，就是因为没有找到mapper映射文件。
在Maven项目中目录分为：
----java
----resources
----webapp
java中编写：java代码
resources中编写：各种配置文件
webapp中编写：表示层
解决方法：只需把mapper映射文件放置在resources目录下，spring配置文件中mapperLocations的值，直接写resources下的路径就好，如下图：
<property name="mapperLocations" value="classpath:MybatisMapper/*.xml"/>其他： classpath:/xxx 和 classpath:xxx是一样的
classpath:xxx 和 classpath*:xxx是不一样的，前者表示引入一个，后者表示引入多个。
