对于这个错误:
=============================
修改applicationContext-*.xml文件:
修改完之后:
=================================
为什么这么改？
==================================================
1.因为eclipse中Package Explorer的目录结构：
/milk-management-service
/milk-management-service/src/main/java
com.milk.service.impl
/milk-management-service/src/main/java/com/milk/service/impl/ItemCatServiceimpl.java
/milk-management-service/src/main/java/com/milk/service/impl/ItemServiceImpl.java
/milk-management-service/src/main/resources
/milk-management-service/src/main/resources/conf
/milk-management-service/src/main/resources/conf/client.conf
/milk-management-service/src/main/resources/conf/db.properties
/milk-management-service/src/main/resources/conf/resource.properties
/milk-management-service/src/main/resources/mybatis

/milk-management-service/src/test
/milk-management-service/target
===========================================
项目的加载顺序是:先进入service模块web.xml去寻找:
=================
再去根据路径去进入spring/applicationContext-*.xml，、
============================
然后，在spring/applicationContext-dao.xml中找到
看这个路径有没有配错，按这个路径去寻找一个叫做db.properties的文件，看路径错没错。
