classpath*:/servlet-context.xml will load every servlet-context.xml resource from the root of your application's classpath.

/myproject/WebContent/WEB-INF/spring/appServlet/servlet-context.xml, however, isn't on the classpath root at all, and so Spring will ignore your file and build an empty context.

Try moving servlet-context.xml to be directly under WEB-INF/classes (i.e. to WEB-INF/classes/servlet-context.xml).

Alternatively, move it to WEB-INF/classes/spring/appServlet/servlet-context.xml, and change your code to classpath*:/spring/appServlet/servlet-context.xml
