spring引导和调用存储过程注释或entityManger？

Question

有人可以告诉我调用存储过程的正确方法是什么？

1. I've seen annotations to call a procedure like : 
   @Procedure: In this case I have seen that they create the procedure in the entity,
   but I think it is not most optimal.
   @Query: I have been able to call my procedure with this option, but when I would like a
   parameter to be     null, I don't know how to do it since there is
   not much information. 
2. I've been using entityManager and I've been able to make a parameter null, but I don't know if it's 
   the best way to call a procedure with entityManager

另一件事，创建一个验证数据的程序好吗？还是没有必要，无论是实际情况还是仅在后端有效]

@ NamedStoredProcedureQueries是调用存储过程的更好选择
