Analyzing the causes

  • Setting global variables is not done the right way, you need to use theAtomicReferenceclass for thread-safe operations, set up as follows:
	AtomicReference<JSONArray> threadLocalShoppingCartIdList = new AtomicReference<>(shoppingCartIdList);
	("shoppingCartIdList", threadLocalShoppingCartIdList);
	(isSend, "true");

AtomicReferenceDescription:

  • Atomic Operations:AtomicReference provides atomic reference update operations. This is accomplished through the CAS
    (Compare And Swap) algorithm, which ensures atomic operations on referenced objects and avoids the use of locks.
    The performance overhead associated with the
  • Shared Variables:AtomicReference is used when the same reference object needs to be shared between multiple threads.
    scenarios, it is safe to perform read and update operations on referenced objects.
  • Inter-Thread Communication: AtomicReference is mainly used to implement the AtomicReference for shared variables in a multi-threaded environment.
    operations, a tool for concurrent programming.
  • How do I take out a safe variable after setting it? The method is as follows:
