How to remove the error prompt that thymeleaf uses @ {} in idea

for some reasons, properties like data-url= "" need to be rendered, but there is a red wavy line prompt in idea. Although it can be run, it looks very awkward. Can you set it without prompt? Thank you!
use version: idea 2017.3, thymeleaf 3
