Why Don't you use a Bean with the @Scope('request')

@Component
@Scope(value="request", proxyMode= ScopedProxyMode.TARGET_CLASS)
class UserInfo {
   public String getPassword() {
      return password;
   }

   public void setPassword(String password) {
      this.password = password;
   }

   private String password;
}

and then you can Autowireed this bean in both filter and controller to do setting and getting of data.

lifecycle of this UserInfo bean is only exisits within the request so once the http request is done then it terminates the instance as well
