Spring Simplify hasText and containsElement methods for better clarity

• In the containsElement method, I replaced the null check with the isEmpty method to enhance readability.
• In the hasText method, I substituted the length check with isEmpty to reduce code duplication.

Hi @dukbong,

Thanks for the proposal; however, we are happy with the current implementation of these internal utility methods.

In light of that, I am closing this PR.
