java - How avoid calling setApplicationContext on a Spring -

i'm setting spring mvc project thymeleaf, following tutorial at: http://www.thymeleaf.org/doc/tutorials/3.0/thymeleafspring.html#spring-mvc-configuration

trying kiss code, first replaced implements applicationcontextaware , setter method @inject private applicationcontext applicationcontext. don't understand why have call setapplicationcontext() on springresourcetemplateresolver while inherits spring interface applicationcontextaware.

how avoid this?

edit: if remove templateresolver.setapplicationcontext(applicationcontext); line, exception when accessing root:

note: use latest versions: spring 4.3.3.release , thymeleaf 3.0.2.release (of course imported thymeleaf-spring4).

after re-checking missed, appears missing @configuration annotation source of spring not injecting applicationcontext springresourcetemplateresolver.
