Support Spring @Cacheable

Hi Team, First, thank you for the incredible work you’ve done on this amazing project.

Describe the bug When using Spring @Cacheable annotation within a redis implementation, I can’t see any span reported to zipkin. Spring Cloud : 2.2.6.RELEASE Spring-Boot : 2.3.5.RELEASE

Sample Here a sample and simple code for Cacheable usage The main controller…

 @RequestMapping(value = "/user/v1/{idUser}",
        produces = { "application/json" }, 
        method = RequestMethod.GET)
public ResponseEntity<String> getUser(Integer idUser) {
        Optional<String> userInformation = myService.getUserName(idUser);
        return userInformation.isEmpty() ? ResponseEntity.noContent().build() : ResponseEntity.ok(userInformation.get());
    }

The service…

 @Cacheable(value = "myCacheNameInRedis")
    public Optional<String> getUserName(Integer idUser) {
        //call repository with idUser;
    }

Hi team,

just some words to tell you that, this error is due to a custom LettuceFactory and we did not add BraveTracing when creating it.

Have nice day folks
