can me? stuck...

thymeleaf or neither framework doesn't encourage write logic inside views. poor coding practice.

you can following instead.

create bean method logic below

@bean("urlutil") class urlutil {     string dosomthing() {        newurl.removeparameter("page");        newurl.addparameter("page", "0");        return newurl.tostring();     } } 

access bean inside thymeleaf layout

<a th:href="@{__${@urlutil.dosomthing()}__}">first</a>
