为什么xml文件存在，报错却说文件不存在啊

Answer 1

autowire.xml laluan salah, anda perlu meletakkannya di bawah src, dalam direktori yang sama seperti applicationContext.xml

Answer 2

Fail autowire.xml tidak ditemui Jika anda ingin memasukkannya ke dalam pakej, laluan mesti bermula dari src, classpath:src/com/Spring/autowire/autowire.xml, jika tidak, letakkannya dalam direktori src. . classpath:autowire.xml

Answer 3

Fail autowire.xml tidak boleh ditemui dalam laluan kelas, yang bermaksud lokasinya salah. Hanya letakkannya bersama applicationContext.xml

Answer 4

Letakkannya di dalam src, lapisan paling luar dari semua pakej.
