为什么xml文件存在，报错却说文件不存在啊

Answer 1

autowire.xml路径不对, 你要放到src下面, 和applicationContext.xml同目录

Answer 2

找不到autowire.xml这个文件，如果你要放在包里面，路径要从src开始写，classpath:src/com/Spring/autowire/autowire.xml，要不然就放在src目录下用classpath:autowire.xml

Answer 3

类路径下找不到autowire.xml文件，也就是位置放错了，和applicationContext.xml放一起就行

Answer 4

放在src里面，所有包的最外层。
