java.lang.IllegalArgumentException: Could not resolve placeholder 'crossOrigin' in value "${crossOrigin}" - spring-data-jpa

Question

I am writing test case for controller class. When I am adding cross origin on top of every methods like this #CrossOrigin(origins = "http://localhost:4200")
at that time Test cases running properly without error.
But I don't want to hard code that cross origin on top of every methods. For that I added one variable in application.property file and accessing that variable in controller on top of class.When I added cross origin like this I am able to access my services from other machine. But my test cases getting failed.
when I am comment this #CrossOrigin(origins = "${crossOrigin}") from controller class test cases are running properly.
Can any one tell me why it's happening?

Answer 1

I realize this question is over a year old, however I too ran into this issue.
The solution is one needs to provide the MockMvc with the place holder value.
So the following :
mockMvc = MockMvcBuilders.standaloneSetup(accountController).build();
Should be :
mockMvc = MockMvcBuilders.standaloneSetup(accountController).addPlaceholderValue("crossOrigin","https://some.url.com").build();
