java - How to ensure the same account is not used to log in two different people at the same time in Spring Security? -

-

i have spring mvc app not protect updates of user data transactions.

it assumes single user accessing account data account @ 1 time.

however, if 2 users log in using same authentication credentials, theoretically possible, although unlikely, 2 database updates on same user data overlap , conflict.

is there simple way protect against in spring security?

spring security supports protection against concurrent logins. see 2.3.3 session management instructions of how enable it.
