Correct syntax for javax.servlet.annotation.ServletSecurity

Has anybody got a code sample for javax.servlet.annotation.ServletSecurity annotation.

I have had a look around but all I find are javadoc开发者_运维问答 pages which won´t tell you how javax.servlet.annotation.ServletSecurity and javax.servlet.annotation.HttpMethodConstraint fit together and how a correct annotation should look like.

How about this example? It uses:

@ServletSecurity(
   @HttpConstraint(rolesAllowed = {"Authorized"})
)
