How to secure an URL using hasRole() in Spring Security? Is it enough to hide sections of JSP to protect URL? Example?

One of the Spring security question asked to me on a recent interview was about is it enough to hide portions of JSP to protect a URL from unauthorized access in Spring security? First of all I didn't understand the question, so I ask him to clarify a bit more. He explained to me that there are different roles in his application e.g. DEVELOPER, ADMIN, TRADER, OPERATION and each role can only see the functionalities based upon their role.

The HashMap is only meant to be updated by one thread at a time, hence you don't need to pay any attention to thread-safety or concurrency, but ConcurrentHashMap can be updated by multiple threads at the same time, hence you need to pay special attention.
