Hi @NWuensche,

For single values supplied for an array-typed attribute in an annotation, we typically prefer to omit the braces. The presence of brackets in the @Target declaration in @Repository, @Controller, and @Service is therefore likely just a copy-n-paste error.

I'll address that inconsistency in an upcoming commit.

As a side note, we typically do not accept PRs for minor formatting/style issues like this.

In any case, thanks for submitting your first pull request for the Spring Framework.
