Failed to load ApplicationContext from Unit Test: FileNotFound

try as below

@ContextConfiguration (locations = "classpath*:/spring/applicationContext*.xml")

this will load all 3 of your application context xml file.

I added the spring folder to the build path and, after clean&build, it worked.

Try with the relative path using *

  @ContextConfiguration(locations = {
"classpath*:spring/applicationContext.xml",
"classpath*:spring/applicationContext-jpa.xml",
"classpath*:spring/applicationContext-security.xml" })

If not look if your xml are really on resources/spring/.

Finally try just on without location

 @ContextConfiguration({"classpath*:spring/applicationContext.xml"})

The other error that you´re showing is because you have this tag duplicated on applicationContext.xml and applicationContext-security.xml

 Duplicate <global-method-security>
