Hello，good programmers！

When high concurrency, the log will be printed twice：

like this：

2019-01-01 14:11:55.*766* [INFO ] <T=L0MW82ZxY002Fupw><IP=10.55.63.113> GSOneAuthSource:111: loginName=testetsss,auth in redis,authResult=true
2019-01-01 14:11:55.*767* [INFO ] <T=L0MW82ZxY002Fupw><IP=10.55.63.113> GSOneAuthSource:111: loginName=testetsss,auth in redis,authResult=true

 

I need your help to solve this problem.

thanks!
