There are many ways how you can preserve the user identity in downstream microservices. Here are two of them:

1) Use Spring Session. It gives you the ability to distribute a user session across microservices by simply adding a dependency.

2) Pass the original user's token to downstream calls and have the same Spring Security configuration there.

In both cases, you will be able to get a username from SecurityContextHolder.

@PreAuthorize("hasAnyAuthority('USER_READ', 'USER')")
@GetMapping(value = "/{id}", produces = {MediaType.APPLICATION_JSON_VALUE})
public ResponseEntity<EntityModel<UsersResponseModel>> getUserById(@PathVariable("id") String id) {
    UsersResponseModel respModel = new UsersResponseModel();
    Optional<Users> user = usersSvc.findById(id);
    if(!user.isPresent()) {
    throw new UserExceptions.UserNotFoudException(ErrorsMappings.USER_NOT_FOUND_MESSAGE);
    }
    respModel.setUser(user.get());
    respModel.setCode(HttpStatus.OK.value());

    EntityModel<UsersResponseModel> entity = EntityModel.of(respModel);
    entity = usersProcess.generateHateoas(entity, this, "view-user", user.get().getId());
    return new ResponseEntity(entity, HttpStatus.OK);
}
