Abstract

The application provides a multithreading service exit method, a multithreading service exit device, a storage medium and computer equipment. The method comprises the steps of initializing a record atom variable to enable a counting bit of the record atom variable to be cleared and a state bit to represent that a target service is in an operation state, responding to a call request of any thread to the target service to obtain the state bit, judging whether the state bit represents that the target service is in a stop state, feeding back error call information if yes, enabling the counting bit to be increased by a first numerical value, executing business logic corresponding to the target service, enabling the counting bit to be decreased by the first numerical value after the business logic is executed, and updating the state bit to enable the state bit to represent that the target service is in the stop state in response to a stop service request aiming at the target service, and executing exit logic corresponding to the target service under the condition that the counting bit is cleared. The method solves the problem of service exit logic conflict through a lock-free scheme, and improves the operation efficiency.
