Is there a way to provide an attribute to all models in Spring?-CodePudding

Thymeleaf dropped template expressions like #session, #httpServletRequest etc. in Version 3.1 (https://www.thymeleaf.org/doc/articles/thymeleaf31whatsnew.html).

We used those a lot in relatively large applications. I wrote an interceptor to populate those attributes at every request since I don't want to add them in every Controller needed (like described in the migration guide).

Does anybody know a better way of achieving this?

CodePudding user response：

This is already the best method to populate attributes at each request, compared to the earlier methods defined in the Spring framework documentations.

CodePudding user response：

I learned that @ControllerAdvice can be used in this case (see https://spring.io/blog/2013/11/01/exception-handling-in-spring-mvc).

Classes annotated with @ControllerAdvice, can have methods annotated with @ModelAttribute to populate attributes over multiple Controllers (all of them if not specified otherwise).

In my case:

@ControllerAdvice
public class CommonDataAdvice {
     @Autowired
     private HttpServletRequest request;

     @ModelAttribute("request")
     public HttpServletRequest populateRequest(){
           return request;
     }
}
