Redis distributed lock practice

1, Prevent multiple threads from operating on the same object

		//  Add distributed lock  --  Use optimistic locks , Increase throughput 
        try {
    
            if(redisService.setNx("aisport:joinTeamByInvitationCode")){
    
                
            }
        } catch (Exception e){
    
            e.printStackTrace();
            TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
        } finally {
    
            //  Remember to release the lock 
            redisService.del("aisport:joinTeamByInvitationCode");
        }

2, Prevent the same user from operating the same method multiple times （ Interface idempotence ）

if(!redisService.setNx("removeSportUserToTeam："+aiSportUser.getId(),3)){
    
           return ResultData.error(" Frequent operation , Please try again later !");
       }
