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/test
/milk-management-service/target

===========================================

项目的加载顺序是:先进入service模块web.xml去寻找:

        contextConfigLocation
        classpath:spring/applicationContext-*.xml

=================

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。
