Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [www.csdn.spring.autowire.DeptBean] is defined: expected single matching bean but found 2: deptBean,deptBean1
这两种错误原因:都是spring配置文件中自动装配按byType时出的问题,配置文件, 红色部分为错误的解释和导致错误的原因如下:

乍一看，有些许没有头脑，但是放下心仔细看看，提示说什么users属性怎么怎么滴；还有一点提示就是说是spring-collection.xml配置文件中的错误，这就好找，找到改配置中有关users的地方，
。。。。。
这样的代码肯定不会出错了，如果是这里的错报的就不是这个错了，可能就是第一条或第二条错了；再找下一块有users的地方，找到了这里：
仔细一看真是这里的错，红色部分最开始忘了写，注释掉了上面的list注入值的方式，后面的uti标签注入值有没有写，这是在测试类中取值遍历的时候就会遍历一个空的users，这是因为是没有注入值的错，所以没有报空指针的错，报的是这种莫名其妙的错。
